The Creatine Kinase-MB (CK-MB) test is a blood test used to measure the level of a specific enzyme called creatine kinase-MB in the blood. CK-MB is primarily found in heart muscle cells. When heart muscle is damaged, such as in a heart attack, CK-MB levels rise in the blood.

A DHEA sulfate test measures the levels of dehydroepiandrosterone sulfate (DHEA-S) in your blood. DHEA-S is a hormone produced by your adrenal glands.

A Direct LDL Cholesterol test measures the amount of low-density lipoprotein (LDL) cholesterol in your blood. LDL cholesterol, often referred to as “bad” cholesterol, can build up in your arteries and increase your risk of heart disease.

A creatinine test measures the level of creatinine in your blood. Creatinine is a waste product produced by your muscles. Your kidneys filter creatinine from your blood and remove it from your body through your urine.

Creatine Kinase (CK) is an enzyme found primarily in muscle tissue. It helps to recycle energy in the body. When muscle cells are damaged, CK levels can rise in the bloodstream.
