2. D –Dimer Blood Test
D-Dimer Test
A D-dimer test looks for D-dimer in blood. D-dimer is a protein fragment
(small piece) that's made when ablood clotdissolves in your body.
Blood clotting is an important process that prevents you from losing too much
blood when you are injured. Normally, your body will dissolve the clot once
your injury has healed. With ablood clotting disorder, clots can form when you
don't have an obvious injury or don't dissolve when they should. These
conditions can be very serious and even life-threatening. A D-dimer test can
show if you have one of these conditions.
Other names: fragment D-dimer, fibrin degradation fragment
USED FOR
A D.DIMER test is most oftern used to find out the whether you have blood
clot disorder. These disorder include

3. DEEP VAIN THRODEEPMBOSIS (DVT)
A blood clot that’s deep inside a vein. These clots usually affect the lower legs, But they
can also happen in other pars of the body.

4. Pulmonary Embolism (PE)
A blokage in an artery in lungs. It usually happens when a blood clot in another part of
the body breaks loos and travel to the lungs. DVT clot are a commen couses of PE.

5. Disseminated intravascular coagulation(DIC)
A condition that causes too many blood clot to form.
They can form throughout the body, causing a organ
damage and other serious complications. DIC may be
caused by traumatic injuries or certain types of infection
or cancer.

6. Stroke
A blockage in the blood supply to the brain.

7. Risks Factors D-dimer test
You may have slight pain or bruising at the spot where the needle was put in,
but most symptoms go away quickly.
results mean
If your results show low or normal D-dimer levels in the blood, it means you
probably don't have a clotting disorder.
If your results show higher than normal levels of
D-dimer, it may mean you have a clotting disorder.

But it cannot show where the clot is located or what type of clotting disorder
you have. Also, high D-dimer levels are not always caused by clotting
problems. Other conditions that can cause high D-dimer levels
includepregnancy,heart disease, and recentsurgery.If your D-dimer
results were not normal, your provider will probably order more tests to make a
diagnosis.
If you have questions about your results, talk to your health care provider.
Learn more aboutlaboratory tests, reference ranges, and understanding results.

8. Testing Purpose
Blood clotting disorder, such as deep vein thrombosis (DVT) or a
pulmonary embolism (PE).
Symptoms of DVT include:
Leg pain or tenderness
Leg swelling
Redness or red streaks on the legs
Symptoms of PE include:
Trouble breathing
Cough
Chest pain
Rapid heartbeat

10. Is there anything else I need to know about a D-dimer test?
If your D-dimer test results were not normal, your provider may
order one or more imaging tests to find out if you have a clotting
disorder. These include:
Doppler ultrasound, a test that uses sound waves to create
images of your veins.
CTangiography.In this test, you are injected with a special dye
that helps your blood vessels show up on a special type ofx-
raymachine.
Ventilation-perfusion (V/Q) scan.These are two tests that may
be done separately or together. They both use small amounts of
radioactive substances to help a scanning machine see how well
air and blood move through your lungs.
