Blood Tests Directory
Blood tests are laboratory tests that analyze various parts of your blood. The blood is usually extracted from a vein or from a finger tip via a finger prick. The blood tests can analyze physiological and chemical balances in the body and can determine types of diseases a person may have, how effective drugs are and organ function.
