Tests
An ANA test is a blood test that looks for antinuclear antibodies in your blood. Antibodies are proteins that your immune system makes to fight foreign substances, like viruses and bacteria. But an antinuclear antibody attacks your healthy cells instead. It's called "antinuclear" because it targets the nucleus of the cells, which is in charge of sending signals that are needed for important cell functions.
Tests
The determination of the amount of a complex comprised of angiopoietin-related proteins 3 and 8 in a sample.
Tests
Antibody serology tests look for specific antibodies in your blood. Antibodies are proteins your immune system makes to fight disease-causing germs (also called pathogens), such as viruses and bacteria .
Tests
An ANCA test looks for antineutrophil cytoplasmic antibodies (ANCA) in a sample of your blood. Antibodies are proteins that your immune system makes to fight foreign substances, such as viruses and bacteria. ANCAs, however, are autoantibodies, which are antibodies that attack your own healthy tissues and organs by mistake. This can lead to the development of an autoimmune disease .
Tests
Autoantibody testing checks a sample of your blood for autoantibodies, proteins made by the immune system .
Tests
The determination of the amount of B-cell lymphoma 6 protein in a sample.
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).
Tests
The determination of the amount of the 1-42 amino acid beta amyloid protein isoform present in a sample.
Tests
The determination of the ratio of beta-1 globulin compared to beta protein present in a sample. The measurement may be expressed as a ratio or percentage.
Tests
The determination of the ratio of the beta-1 globulin to albumin in a biological specimen.
Tests
A quantitative measurement for assessing the amount of protein present in a blood sample.
Tests
The determination of the amount of breast cancer type 1 susceptibility protein present in a sample.
