How to Interpret Your Blood Test Results

As patient self-education grows with access to information online, more people are taking charge of their health by buying their own blood tests that they can access online without visiting a doctor. Large blood testing networks located all over the United States make it easy for empowered and educated patients to find a lab location near them where they can have their blood drawn or provide a blood sample, urine sample, or saliva sample. Discounted Labs makes it easy for those consumers to buy and learn how to read blood test results, including the results of conventional blood tests, which can provide valuable insights into human health, including the effects of drugs and environmental contaminants, so that they can have more educated discussions with their physicians.

After people buy their own blood tests and receive their results, it is sometimes difficult to make sense of what high or low blood test values mean when compared with the “normal” ranges provided by blood testing companies. Searching on the Internet may only give people a limited explanation of the health consequences of these high or low blood test values. We will attempt to include the most common blood tests, their normal ranges, and the meaning of high or low values, including the lower limits, as well as individual tests or collections of related tests called panels, to help people understand and monitor their ongoing health conditions. It is important to note that when interpreting blood test results, your clinician will likely focus on test trends relative to their normal ranges and not just the numerical results themselves. This means that if you have results for a given test from different labs, your clinician will look at how your results compare to the normal ranges for that specific test, rather than just the numerical values listed on your lab report. Additionally, these normal ranges are based on statistical analyses of tests from a large number of patients, providing a more accurate understanding of what is considered a healthy range for each test. https://www.discountedlabs.com/blog/how-to-read-blood-test-results

It is produced in a pulsatile fashion and most of it is secreted during periods of deep sleep. Normal Growth Hormone Range 2-5 ng/ml for men and women When GH Blood Test Is High Too much growth hormone can cause gigantism in children or acromegaly in middle-aged adults. Both these conditions are characterized by excessive growth of the bones in the hand and feet. It can be caused by growth hormone therapy or a GH producing pituitary tumor. When GH Blood Test Is Low Growth hormone deficiency might be present at birth and caused by a poorly developed pituitary gland Later on in life, too little growth hormone might signify a tumor or serious disorder with the pituitary that prevents it from secreting growth hormone normally

21. HEMOGLOBIN A1C Hemoglobin a1c is also known as glycated hemoglobin and it measures your average blood sugar levels from the last 2 to 3 months. Although it's not an efficient indicator of diabetes, hemoglobin a1c can be used to monitor its evolution over time. Normal A1C Range 3.8-6.4% for men and women When A1c Blood Test Is High Increased levels of this substance are associated with hyperglycemia in adults Having low levels of hemoglobin a1c is usually not a cause of concern. This can happen if the patient consumes little to no sugar over an extended period of time or fasts for more than 12-24 hours.

22. HIGH-DENSITY LIPOPROTEIN CHOLESTEROL, HDL HDL cholesterol is also known as "good cholesterol". It is usually calculated and interpreted in combination with either total cholesterol values or LDL cholesterol. Studies indicate that for every 5% decrease in HDL, the risk of coronary artery disease increases by 25%. The HDL test is part of the Lipid Panel. Normal HDL Ranges Over 40 mg/dl for men Over 50 mg/dl for women When HDL Blood Test Is High Although too much HDL is a rare occurrence and shouldn't be a problem, it can increase the risk of serious heart disease in people who already had a heart attack When HDL Blood Test Is Low Especially if the triglycerides and LDL cholesterol levels are high, a low HDL cholesterol can significantly increase the risk of heart disease such as arrhythmia, myocardial infarction, etc. The use of higher dose testosterone or anabolic steroids can decrease HDL. Obesity and sedentary lifestyle are known to contribute to low HDL.

23. INSULIN Insulin is a substance produced by the pancreas to help stabilize blood sugar levels. This substance acts as a "key" that opens up the cells in your body, allowing them to absorb glucose and use it for energy production. Normal Insulin Range 2-20 U/ml for men and women When Insulin Blood Test Is High Too much insulin can be caused by a pancreas tumor that triggers an increased secretion When Insulin Blood Test Is Low This can be a sign that diabetes type 1 was treated improperly Might also be a sign of insulin resistance syndromes or endogenous hyperinsulinemia

It can also be caused by very high doses of statins.

26. IRON Iron is an important element in the human body. It helps with the production of red blood cells and prevents the onset of anemia, a condition characterized by permanent fatigue and lack of energy. Iron also helps to transport oxygen to the various cells and tissues in the body. Normal Iron Range 45-180 ug / dL for men and women When Iron Blood Test Is High This might indicate conditions such as hemolytic anemias, poisoning with lead, acute leukemia, hepatitis or a deficiency of vitamin B6 Too much iron can also be associated with hemochromatosis and nephritis Taking higher doses of iron supplements can also cause high iron When Iron Blood Test Is Low This can signify severe anemia, acute or chronic infection in the body, carcinoma or hypothyroidism Low amounts of iron in the blood are also associated with nephrosis , shortness of breath, paleness, and heart palpitations Other causes of low iron are frequent blood donations, or internal bleeding.

27. LUTEINIZING HORMONE (LH) The luteinizing hormone (LH) plays a vital role in the reproductive organs for both men and women.

Mean corpuscular hemoglobin (MCH) is a calculation of the amount of oxygen-carrying hemoglobin inside your red blood cells (RBCs). A high MCHC indicates an increased level of hemoglobin in your RBCs. Normal MCH Range 27.5 and 33.2 picograms ( pg ) per cell When MCH Blood Test Is High A high MCH indicates an increased level of hemoglobin, the oxygen-carrying protein, in your RBCs. Increases can be associated with anemia. Often, increased MCH occurs in conjunction with a high mean corpuscular volume—or large red blood cells-which suggest macrocytic anemia. High MCH can also be linked to low blood levels of B-12 or folate. When MCH Blood Test Is Low A low MCH indicates that you have a decreased level of oxygen-carrying protein in your red blood cells. Decreases can be associated with certain types of anemia. Often, decreases occur in conjunction with low mean corpuscular volume—or small RBCs—which suggest microcytic anemia. Hypochromic anemia, resulting from hemoglobin deficiency, can be a possibility as well.

30. MEAN CORPUSCULAR VOLUME (MCV) Mean Corpuscular Volume (MCV) is the average size, or volume, of individual red blood cells. Normal MCV Range 80–100 femtoliters When MCV Blood Test Is High A high MCV indicates large, or macrocytic, RBCs.

When MCV Blood Test Is Low A low MCV indicates small, or microcytic, red blood cells. A low MCV is associated with anemia, and can indicate an iron deficiency, chronic illness or the hereditary disease, and thalassemia.

31. PHOSPHORUS, INORGANIC (ADULT) Phosphorus is the second most common mineral in the body. It makes up for about 1% of a person's weight and its main role is to help in the formation of bones and teeth. The highest levels of phosphorus in the bloodstream usually occur in the morning and they gradually drop to lower levels in the evening. Normal Phosphorus Range 2.6-4.5 mg/dl for men and women When Phosphorus Blood Test Is High This can be a sign of intoxication with vitamin D, bone tumors or even leukemia Too much phosphorus might also be a sign that some bones are healing inside the body as well as hypoparathyroidism or renal failure In some cases, it can be associated with respiratory acidosis or pulmonary embolism When Phosphorus Blood Test Is Low You might experience severe fatigue, muscle weakness, and lack of energy It might contribute to the development of joint pain or bone disorders

32. POTASSIUM Potassium is one of the most important electrolytes in the body. Electrolytes help to transport electrical impulses to and from organs and tissues. Potassium is not produced in the body, so it must be taken from various foods such as bananas, nuts, beans, whole grains, and lean meats. Normal Potassium Range 3.4-4.8 mmol /liter for men and women When Potassium Blood Test Is High This is also known as hyperkalemia and it's usually associated with a poor excretion of potassium through the kidneys It can also be a sign of anorexia nervosa, dehydration, tissue damage or hemolysis The most common cause of high potassium is kidney disease. Some blood pressure medications can increase serum potassium Uncontrolled diabetes Injuries that cause severe bleeding Some rare diseases can cause high potassium When Potassium Blood Test Is Low This might be a sign of an adrenal disorder such as the Cushing syndrome Low potassium (hypokalemia) has many causes. The most common cause is excessive potassium loss in urine due to prescription medications that increase urination. Also known as water pills or diuretics, these types of medications are often prescribed for people who have high blood pressure or heart disease.

33. PROGESTERONE Progesterone is produced in the ovary and it plays a vital role in maintaining a pregnancy. It also plays an important role in brain function in men and women and it can be used as a medication to treat different hormonal disorders. It's important to note that the levels of progesterone in a woman's body vary throughout the month, depending on her ovulation phase. The progesterone levels skyrocket if the woman is pregnant. Normal Progesterone Ranges Less than 1 ng/ml for men More than 1 ng/ml for a female during the follicular phase 3-20 ng/ml during the mid-luteal phase When Progesterone Blood Test Is High If the woman is not pregnant, this can be a sign of an ovarian problem such as an ovarian cyst or ovarian cancer. If the woman is pregnant, high levels are normal High progesterone can also be caused by hormone replacement therapy (HRT) When Progesterone Blood Test Is Low Low progesterone levels in women are usually associated with infertility problems and might lead to poor ovarian function Low progesterone in men may be caused by testosterone or anabolic steroid use. It can be linked to sleep issues and anxiety.

34. PROLACTIN Prolactin is a hormone produced by the pituitary gland. It influences the lactation process, but it also plays an important role in the functioning of the immune system. In some cases, it can also influence the behavior of the individual. Normal Prolactin Ranges 0-15 ng/ml for men 0-20 ng/ml for premenopausal women 0-15 ng/ml for postmenopausal women When Prolactin Blood Test Is High In men, too much prolactin might lead to impotence, galactorrhea , low libido, and even infertility. It can be caused by pituitary adenomas (tumors). High prolactin can decrease testosterone production and cause erectile dysfunction. It can also cause nipple discharge in some men. Caution: Blocking prolactin may cause heart issues. In women, too much prolactin might interfere with the ovulation process and reduce the secretion of estrogen and progesterone When Prolactin Blood Test Is Low Although very rare, this might reduce the production of milk in women who just gave birth. It might also be a sign of a poorly functioning pituitary gland Low prolactin in men can be caused by higher doses of cabergoline or other prolactin antagonists.

35. PROSTATE-SPECIFIC ANTIGEN (PSA) The prostate-specific antigen is a type of protein produced by both healthy and unhealthy prostate tissue. It acts as a marker for detecting prostate cancer as well as monitoring the recurrence of prostate-related diseases like prostatitis. Normal PSA Range 0.0-2.0 ng/ml for men under 40 years of age 0.0-4.0 ng/ml for 40 years old men or older When Psa Blood Test Is High It might be a sign of prostatitis or benign prostatic hyperplasia A high PSA level might also be caused by vigorous exercise or surgery In some cases, high PSA levels are associated with prostate cancer When Psa Blood Test Is Low It might indicate prostate tumors, but usually, more tests are required to confirm the diagnosis

36. PROTEIN, TOTAL Potassium is one of the most important electrolytes in the body. Electrolytes help to transport electrical impulses to and from organs and tissues. Potassium is not produced in the body, so it must be taken from various foods such as bananas, nuts, beans, whole grains, and lean meats. Normal Protein Range 6.0-8.0 g/dl for men and women When Protein Blood Test Is High Too much protein in the bloodstream might be associated with anabolic steroid use High serum protein can also be a sign of insulin progesterone, epinephrine or corticosteroids preparations When Protein Blood Test Is Low This can signify malnutrition, malabsorption syndrome or a chronic liver disease

Normal Sodium Range 135-145 mmol /liter for men and women When Sodium Blood Test Is High This can be a sign of Cushing's syndrome Too much sodium might also be a sign of increased renal sodium retention in hyperaldosteronism When Sodium Blood Test Is Low Also known as hyponatremia, too little sodium in the blood might signifies diuretics abuse, salt-losing nephropathy or excessive sweating Low sodium might also be caused by excessive vomiting or diarrhea

38. SOMATOMEDIN C (INSULIN-LIKE GROWTH FACTOR I , IGF-1) IGF-1 plays a vital role during childhood and it can have anabolic effects in adults. This hormone acts like insulin as it helps to control the blood sugar level. It's produced by the liver and it can be influenced by growth hormone. It increases with hunger as Ghrelin is produced by the stomach. Normal IGF-1 Ranges 182-780 ng/ml for people between 16 and 24 years 114-492 ng/ml for people between 25 and 39 years 90-360 ng/ml for people between 40 and 54 years 71-290 ng/ml for people older than 54 years When It's Too High This might be a sign of acromegaly, especially if the growth hormone levels are also high. This may be caused by a pituitary tumor. High IGF-1 can be caused by high growth hormone therapy doses. When It's Too Low Low IGF-1 might be caused by hypothyroidism, liver disease or uncontrolled diabetes. It can slow down height in children.

39. TOTAL TESTOSTERONE TEST Testosterone is the most important male sex hormone. It starts the development of primary and secondary sex characteristics in pubertal boys and it helps to produce sperm in adult men. It is linked to libido, lean body mass, and motivation in men and women. You can find a cheap testosterone test on discountedlabs.com Normal Testosterone Ranges (Depends On Laboratory) 350-1070 ng/dl for men 6-86 ng/dl for women When Testosterone Blood Test Is High This can be a sign of high testosterone doses.

When Testosterone Blood Test Is Low It can lead to hypogonadism and low sex drive in men It can be caused by illness, head injuries, opiate or anabolic steroid use, exposure to environmental toxins, high prolactin caused by pituitary adenomas, testicular dysfunction, malnutrition, certain medications, or low LH produced by the pituitary gland. In women, low testosterone can be caused by illness, ovarian or adrenal dysfunction, opiate or anabolic steroid use, excessive exercise, and other factors

40. FREE TESTOSTERONE TEST Free or unbound testosterone makes up for about 1% to 2% of the total testosterone people have in their bodies. This type of testosterone is not bound to proteins such as albumin or sex hormone-binding globulin. It is responsible for most of the functions attributed to testosterone (libido, mood, etc.) Normal Free Testosterone Ranges for Men & Women 15.0-40.0 pg /ml for males between 20 and 40 years 13.0-35.0 pg /ml for males between 41 and 60 years 12.0-28.0 pg /ml for males between 61 and 80 years 0.6-3.1 pg /ml for females between 20 and 40 years 0.4-2.5 pg /ml for females between 41 and 60 years 0.2-2.0 pg /ml for females between 61 and 80 years When Free Testosterone Blood Test Is Low It's usually associated with hypogonadal symptoms in men and women. Low free testosterone is usually caused by low total testosterone, or by high sex hormone binding globulin (SHBG). When Free Testosterone Blood Test Is High High free testosterone is usually caused by high total testosterone (high TRT doses), anabolic steroid use, or low SHBG.

41. THYROID-STIMULATING HORMONE (TSH) TEST The TSH is produced by the pituitary gland. It directly stimulates the thyroid and makes it secrete different types of thyroid hormones that are involved in energy production and other metabolic processes. Normal TSH Range 0.5-5.0 U/ml for men and women (some physicians treat based on a range of 0.5-2.5) When TSH Blood Test Is High High TSH levels can mean your thyroid is not making enough thyroid hormones, a condition called hypothyroidism, especially when it's associated with fatigue, depression, and constipation High TSH can also be caused by iodine supplementation When TSH Blood Test Is Low It might be a sign of an overly active thyroid or hyperthyroidism. It can be accompanied by irregular heartbeats, nervousness, and muscle weakness Low TSH can be caused by thyroid hormone replacement

42. THYROXINE (T4) AND TRIIODOTHYRONINE (T3) Hormonal production of the thyroid gland is constituted of thyroxine or T4 (80%) and triiodothyronine or T3 (20%). In the circulation, whole T4 originates from thyroid secretion but most of T3 (80%) is produced outside the thyroid from T4 deiodination . Conversion of T4 to T3 may be influenced by various conditions and circulating T3 is a less reliable reflection of thyroid hormone production than T4. In blood most of T4 and T3 is bound to binding proteins and only 0.02% of T4 and 0.3% of T3 is free. Because of their higher diagnostic performance, free T4 (FT4) and free T3 (FT3) measurements have superseded total (free + bound) hormone determination.

43. Free T3 Measures the free T3 hormone levels. This test can be really useful for finding out what amount of active thyroid hormones are available for the thyroid receptor sites. Free T3 blood test is high in hyperthyroid conditions and low in hypothyroid conditions. May also be high in thyroid toxicosis . Free T4 Used to measure the amount of free or active T4 in the blood. High with hyperthyroidism, low with hypothyroidism. The drug Heparin can also cause elevated free T4 as can some acute illness. It’s also high in an overdose of thyroid hormone. Normal Total T4 Range 4.5-10.9 g/dl for men and women When T4 Blood Test Is High Too much thyroxine is commonly associated with hyperthyroidism When T4 Blood Test Is Low This can be a sign of a poorly functioning thyroid gland or hypothyroidism

44. When these antibodies are present, it means that your immune system is attacking your own tissue. When your body produces thyroid autoantibodies it could create a hypo- or hyper- thyroid state. They may also be elevated if there is thyroid cancer. Some antibodies can attach to TSH receptors, but they don’t cause a response in the thyroid. These patients will complain of low thyroid symptoms, but the TSH might not change at all. In other cases, the antibodies bind to receptor sites and cause the thyroid to be overactive. Here you will see high T4, low TSH and high antibodies. Thyroid Antibody Tests Thyroid Peroxidase Antibody (TPO Ab): Thyroglobulin Antibodies ( TgAb ): This antibody is the one that is usually high in autoimmune thyroid conditions like Hashimoto’s. It is also known as microsomal antibody. These aren’t seen high as often as TPO Ab. They are usually ordered when thyroid lab results seem strange because these antibodies can interfere with thyroid hormone production. TgAb is also used to monitor progress after surgery for removing the thyroid in thyroid cancer. You can buy thyroid tests on DiscountedLabs.com
