Lab tests for leukemia

Lab tests for leukemia

A complete blood count is one of several common tests for leukemia. It measures the amount of red blood cells, white blood cells and platelets in the blood, which are often lower than normal from the disease.

Another lab test used for leukemia is a liver function test. A liver function test is a group of blood tests used to measure the amounts of certain enzymes released by the liver in response to damage or disease. An abnormal liver function test may indicate the presence of leukemia.

What are lab tests?

A complete blood count (CBC) is a common laboratory test used to measure blood counts (or the number of blood cells circulating in the bloodstream). A CBC measures the level of red blood cells (which carry oxygen throughout the body), white blood cells (which fight infection) and platelets (which help with blood clotting) in a blood sample. A CBC also measures hemoglobin (a protein in red blood cells that carries oxygen) and hematocrit (the ratio of red blood cells to plasma).
