Before a diagnosis or treatment, a health professional should conduct a thorough diagnostic evaluation, including an interview and a physical examination. In some cases, a blood test might be done to make sure the depression is not due to a medical condition like a thyroid problem or a vitamin deficiency (reversing the medical cause would alleviate the depression-like symptoms).
