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.

An anion gap blood test gives a measurement of the acid-base balance (pH balance) in your blood. This lets you know whether your blood is too acidic or not acidic enough. The test also checks for an electrolyte imbalance in your blood. To do the measurement, an anion gap test uses the results of an electrolyte panel or other blood tests that measure your electrolytes.

An anti-müllerian hormone (AMH) test measures the amount of AMH in a blood sample. In males, the testicles (or testes), which are glands that make sperm and hormones, make AMH. In females, the ovaries, which are glands that store and develop eggs and make hormones, make AMH.

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 .

An arterial blood gas (ABG) test measures the amount of oxygen and carbon dioxide (CO2) in a sample of your blood. The blood oxygen measurement shows how well your lungs move oxygen from the air into your blood when you breathe in. The carbon dioxide measurement shows how well your lungs remove carbon dioxide from your blood when you breathe out.
