Blood tests show whether the levels of different substances in your blood fall within a normal range.

• For many blood substances, the normal range is the range of levels seen in 95 percent of healthy people in a certain group. For many tests, normal ranges vary depending on your age, gender, race, and other factors.

• Your blood test results may fall outside the normal range for many reasons. Abnormal results might be a sign of a disorder or disease. Other factors—such as diet, menstrual cycle, physical activity level, alcohol intake, and medicines (both prescription and over the counter)—also can cause abnormal results.

• Your doctor should discuss any unusual or abnormal blood test results with you. These results may or may not suggest a health problem.

• Many diseases and medical problems can't be diagnosed with blood tests alone. However, blood tests can help you and your doctor learn more about your health. Blood tests also can help find potential problems early, when treatments or lifestyle changes may work best.
