Consuming fewer than 20 grams of carbs daily is known as a ketogenic diet, or a very low-carb diet. The brain only uses glucose or ketone bodies for energy. When you restrict your glucose intake due to a low carb intake, your body converts fats into ketone bodies.
The mononucleosis test is used to help determine whether a person with symptoms has infectious mononucleosis (mono). The test is used to detect proteins in the blood called heterophile antibodies that are produced by the immune system in response to an Epstein-Barr virus (EBV) infection, the most common cause of mono. A mono test is frequently ordered along with a complete blood count (CBC).
Mono tests include: 1  Monospot test (heterophil test). This quick screening test detects a type of antibody (heterophil antibody) that forms during certain infections. 2  EBV antibody test. For this test, a sample of blood is mixed with a substance that attaches to antibodies against EBV. A series of tests can detect different types of antibodies to help determine whether you were infected recently or sometime in the past.
