Individual tests

The aPTT is one of several blood coagulation tests. It measures how long it takes your blood to form a clot. When one of your blood vessels is damaged, proteins called clotting factors come together to form clots and quickly stop the bleeding. The aPTT test helps assess how well those clotting factors work, often in conjunction with other tests that monitor clotting factors.
A blood smear is a sample spread on a glass slide and treated with a special stain. Previously, all blood smears were examined under a microscope by laboratory professionals. Now automated digital systems can help examine blood smears. A blood smear helps diagnose and monitor conditions such as blood disorders, sudden kidney failure, and certain cancer treatments.
A blood type can be classified into four common groups known as the ABO system: A, B, AB, or O. A second system, the Rh system, determines if the blood type is Rh-positive or -negative. Blood typing is a common test before blood transfusions, tissue transplants, and during pregnancy.
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.
A complete blood count is a common blood test that is often part of a routine checkup. This test can help detect a variety of disorders, including infections, anemia, immune system disease, and blood cancers.
A complete blood count is a screening test for various disease states including anemia, leukemia, and inflammatory processes. This test is analyzed based on blood from the cord.
A complete blood count is a common blood test in routine checkups. This test can help detect various disorders, including infections and anemia. A reticulocyte count measures the number of immature red blood cells (reticulocytes) in your bone marrow to find out if you are producing enough red blood cells.
Creatine Kinase is an enzyme found in heart, brain, and skeletal muscle. This test detects muscle inflammation or damage due to muscle disorders.
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.
The direct Coombs test detects antibodies stuck to the surface of red blood cells. Many diseases and drugs can cause this to happen. These antibodies sometimes destroy red blood cells, causing anemia. Your healthcare provider may recommend this test if you have signs or symptoms of anemia or jaundice (yellowing of the skin or eyes).
Glucose-6-phosphate dehydrogenase (G6PD) deficiency is a genetic disorder affecting red blood cells, which carry oxygen from the lungs to tissues throughout the body. The disease can cause hemolysis, where red blood cells are destroyed faster than the body can replace them.
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.
