Common types of blood tests that your doctor might order include:
Complete Blood Count (CBC)
This blood test is the one that is most commonly ordered by doctors. By measuring the types and numbers of cells in your blood, including your red and white blood cells and platelets, this test will give your doctor a good determination of your overall health status. It can be a helpful tool in screening for disorders and evaluating your nutritional status. When you have symptoms such as fatigue, weakness and bruising, your doctor can use this test to help diagnose whether these symptoms could be a condition such as anemia, leukemia, malaria, or another type of infection.
Basic Metabolic Panel
Your doctor will order this kind of blood test to measure your blood chemistry. The test measures certain compounds in your blood including glucose, sodium, potassium, calcium, chloride, carbon dioxide, blood urea nitrogen and creatinine. The test is used to monitor the effects of certain medications you are taking, such as those to prevent high blood pressure. It can also determine your blood sugar level and fluid balance, and it will tell your doctor how your kidneys are functioning. When additional testing is needed, your doctor will order a...
Comprehensive Metabolic Panel (CMP) to further evaluate organ systems and metabolic functions. The CMP measures additional proteins and substances in the blood related to liver function.
C-Reactive Protein (CRP) Test
When tissues in your body are inflamed, your liver produces C-Reactive Proteins. This test measures the level of CRP present in your blood. High levels of this protein can indicate a higher risk of heart disease. CRP can be caused by a variety of things, including:
Hemoglobin is a protein in red blood cells that carry oxygen throughout the body. This test determines the body’s average blood sugar level over a period of 2-3 months by measuring what percentage of hemoglobin is coated with sugar. The test is used to measure your risk for diabetes and is also used to monitor the disease.
The thyroid panel, or thyroid function test, checks the function of the thyroid gland. It measures the amount of the thyroid-stimulating hormone (TSH) in your blood. TSH stimulates the thyroid gland to produce and release thyroid hormones into your blood. These hormones stimulate the metabolism of nearly every tissue in the body.
This test, also called PT or Pro Time, is used to measure the presence and activity of different clotting factors in the blood, and how long it takes plasma (liquid portion of the blood) to clot. It can be used to screen for bleeding abnormalities and is also used to evaluate the effectiveness of treatments using medications to prevent the formation of blood clots.
Doctors recommend that routine blood tests be done at least once a year. The risks of routine blood tests are low. Some people experience pain or discomfort from the needle puncture. Fainting from blood loss or a vein puncture can also happen. Blood tests are an important way for your doctor to determine your overall health. They can identify illness or disease in the early stages and help your doctor know how you are responding to treatments. Overall, the benefits of routine blood tests far outweigh the risks.
