Creatine kinase (CK) is an enzyme that occurs naturally in your muscle cells, while CK-MB mainly occurs in your heart's muscle cells. Damage to heart muscle cells causes CK-MB to leak into your blood. This test helps detect how much CK-MB enzyme is in your blood. If there’s more CK-MB in your blood than there should be, it can be a sign you’ve had a heart attack.
D-dimer is a protein fragment produced when a blood clot dissolves in your body. Blood clots prevent you from losing too much blood when injured. Normally, your body will dissolve the clot once your injury heals. With a clotting disorder, clots form when you aren't injured or don't dissolve when they should. These conditions are serious and potentially life-threatening. A D-dimer test can show if you have one of these conditions.
Homocysteine is an amino acid that your body uses to make proteins. Normally, vitamin B12, B6, and folic acid (also called folate or vitamin B9) quickly break down homocysteine and change it into other substances your body needs. High levels of homocysteine in your blood may indicate that this process isn't working properly or that you lack certain B vitamins. This test can suggest vitamin B6, B12, and folic acid deficiency, or assess risk factors for heart disease and stroke.
Troponin-I is a protein found in your heart muscles. When these muscles become damaged, troponin is released into the bloodstream. High levels of troponin in the blood may mean you are having or recently had a heart attack. Quick diagnosis and treatment can save your life.
Troponin-T is a protein found in your heart muscles. When the muscles become damaged, troponin is sent into the bloodstream. High levels of troponin in the blood may mean you are having or recently had a heart attack which happens when blood flow to the heart gets blocked. This blockage can be deadly. However, quick diagnosis and treatment can save your life.
C-reactive protein (CRP) is a protein from your liver. Typically, you have low levels in your blood. The high-sensitivity C-reactive protein (hs-CRP) test can detect CRP at lower levels than standard tests. This assesses heart disease and stroke risk in individuals suspected to be at risk of disease.
Lactate Dehydrogenase (LDH) is an enzyme which plays an important role in making your body's energy. It is found in almost all the body's tissue, including those in the blood, heart, kidneys, brain, and lungs. When these tissues are damaged, they release LDH into the bloodstream or other body fluids. If your LDH blood or fluid levels are high, it may mean certain tissues in your body have been damaged by disease or injury.
NT-proBNP is produced by the heart. An elevated NT-proBNP suggests that the heart is not pumping enough blood, known as heart failure or congestive heart failure. The test is used to diagnose or rule out heart failure. In patients with heart failure, testing helps assess disease severity, make decisions, and evaluate treatment effectiveness.
