Tests

Ammonia Levels

An ammonia levels test measures the amount of ammonia in a sample of your blood. Ammonia is also called NH3. It is a normal waste product in your body. Healthy bacteria in your intestines make ammonia when you digest protein in the foods you eat.

Tests

Amylase Test

An amylase test measures the amount of amylase in your blood or urine (pee). Amylase is an enzyme, a protein that speeds up chemical reactions in your body. Amylase helps you digest carbohydrates . Most of the amylase in your body is made by your pancreas and salivary (spit) glands.

Tests

ANA (Antinuclear Antibody) Test

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.
