Blood chemistry tests/basic metabolic panel
The basic metabolic panel (BMP) is a group of tests that measures different naturally occurring chemicals in the blood. These tests usually are done on the fluid (plasma) part of blood. The tests can give providers information about your organs, such as the heart, kidneys, and liver.
The BMP includes blood glucose, calcium, and electrolyte tests, as well as blood tests that measure kidney function. Some of these tests require you to fast (not eat any food) before the test, and others don't. Your provider will tell you how to prepare for the test(s) you're having.
Used for:
Blood enzyme tests
Blood enzyme tests may be used to check for heart attack. Enzymes are chemicals that help control chemical reactions in your body. There are many types of blood enzyme tests. The ones for heart attack include troponin and creatine kinase (CK) tests.
Blood levels of troponin go up when a person has muscle damage, including damage to the heart muscle. In addition, an enzyme called CK-MB is released into the blood when the heart muscle is damaged. High levels of CK-MB in the blood can mean that you've had a heart attack.
Used for:
- Heart Attack
Lipoprotein panel
A lipoprotein panel, also called a lipid panel or lipid profile, measures the levels of LDL and HDL cholesterol and triglycerides in your blood. Cholesterol and triglyceride levels that are higher or lower than normal may be signs of higher risk of coronary heart disease.
A lipoprotein panel gives information about your:
- Total cholesterol
- LDL ("bad") cholesterol, which is the main source of cholesterol buildup and blockages in the arteries
- HDL ("good") cholesterol, which helps decrease cholesterol blockages in the arteries
- Triglycerides, which are a type of fat in your blood
Most people will need to fast for 9 to 12 hours before a lipoprotein panel.
Used for:
- Atherosclerosis
- Blood Cholesterol
- Coronary Heart Disease
- High Blood Triglycerides
Blood clotting tests
Blood clotting tests are sometimes called a coagulation panel. These tests check proteins in your blood that affect the blood clotting process. Levels that are higher or lower than normal might suggest that you're at risk of bleeding or developing clots in your blood vessels.
Blood clotting tests also are used to monitor people who are taking medicines to lower the risk of blood clots. Warfarin and heparin are two examples of such medicines.
Used for:
- Bleeding Disorders
- Blood Clotting Disorders
- Platelet Disorders
Bone marrow tests
Bone marrow tests check whether your bone marrow is healthy and making normal amounts of blood cells. The two bone marrow tests are aspiration and biopsy.
- Aspiration collects a small amount of bone marrow fluid through a larger needle.
- Biopsy tests are often done at the same time as the aspiration test. A biopsy test collects a small amount of bone marrow tissue through a larger needle.
These tests can help find the cause of low or high blood cell counts. They also play an important role in checking how well treatments for certain types of cancers, such as leukemia or lymphoma, are working.
Before this procedure, be sure to tell your provider about current medicines you are taking, known allergies to medicines, if you are pregnant, or if you have a bleeding disorder.
Bone marrow tests can be done in a hospital or doctor’s office or clinic. You may be awake for your test and may be given medicine to relax you during the test. You may also be under anesthesia for this test, if recommended by your care team. You will lie on your side or stomach or back, depending on where your provider obtains the samples from. Your provider will clean and numb the top ridge of the hipbone or rib bone, where the needle will be inserted. You may feel a brief, sharp pain when the needle is inserted and when the bone marrow is aspirated. The bone marrow samples will be studied in a laboratory.
After your test, you will have a small bandage on the site where the needle was inserted. Most people go home the same day. You will need a ride home if you received medicines to relax you during the test. You may have mild discomfort but likely won’t have any pain after the test. Your doctor may have you take an over-the-counter pain medicine. Call your provider if you are in serious pain or if you develop symptoms including:
- Fever
- Redness
- Swelling
- Discharge at the needle injection site
Used for:
- Anemia
- Platelet Disorders
