Tests
A bacteria culture test can determine if you have a bacterial infection and, if so, which type of bacteria is causing it. To do a bacterial culture test, you will need to give a sample of your blood, urine, skin, or other tissue. The type of sample depends on where the infection is located.

Tests
A basic metabolic panel (BMP) measures eight different substances in your blood. It provides important information about your body's fluid balance , your metabolism (the process your body uses to make energy from food you eat), and how well your kidneys are working. This test is often used to check your general health.
Tests
A BCR-ABL1 genetic test uses a sample of blood or bone marrow to look for an abnormal gene called BCR-ABL1. This abnormal gene is found in certain types of blood cancer , such as chronic myeloid leukemia (CML).
Tests
A beta-2 microglobulin tumor marker test measures the amount of a protein called beta-2 microglobulin (B2M) in your body fluids. The test usually uses a sample of your blood. It may also be done using urine (pee) or in rare cases cerebrospinal fluid (CSF).
Indicators
Beta-2-microglobulin protein (119 aa, ~14 kDa) is encoded by the human B2M gene. This protein plays a role in immune responses and is a key component of major histocompatibility complex class I molecules. The protein is localized to the surface of cells and is utilized as a prognostic marker in persons with cancers that involve white blood cells. The polypeptide is also used as a marker in kidney damage diagnosis and in the detection of viral infection.
Tests
An assay designed to standardize measurement of serum inhibitors of blood clotting in a factor VIII neutralization assay.
Article
Research record from Clin Chim Acta, 2026-10-09. PMID 42855111.
Indicators
A dark orange, yellow pigment that is the product of the breakdown of iron in the blood; it is conjugated in the liver and excreted in the bile.
Tests
A bilirubin blood test measures the levels of bilirubin in your blood. Bilirubin is a yellowish substance made during your body's normal process of breaking down old red blood cells. Bilirubin is found in bile, a fluid your liver makes to help you digest food.
