Tests
An immunoglobulins blood test measures the amount of immunoglobulins in your blood. Immunoglobulins are also called antibodies. Antibodies are proteins that your immune system makes to fight germs , such as viruses and bacteria . Your body makes different kinds of antibodies to fight germs in different parts of the body and at different stages of an infection.
Tests
Clinical laboratory tests that examine antigen-antibody reactions in whole blood or its cellular and/or fluid components that may impact natural processes, such as fertility, and clinical procedures affected by tissue and blood compatibility, such as transplants and transfusions.
Tests
An insulin in blood test measures the amount of insulin in a sample of your blood. Insulin is a hormone that your pancreas makes. Hormones are chemical messengers in your bloodstream that control the actions of certain cells or organs.
Tests
Iron tests measure different substances in the blood to check iron levels in your body. Iron is a mineral that your body needs for growth and development. Your body uses iron to make hemoglobin, a protein in red blood cells. It carries oxygen from the lungs to all parts of the body, Iron is also important for healthy muscles, bone marrow, and organ function. Your body also needs iron to make some hormones .
Tests
A ketones in blood test measures the level of ketones in your blood. Ketones are acids that your body makes when it breaks down fat for energy.
Tests
A ketones in urine test measures ketone levels in your urine. Normally, the cells in your body use blood glucose (also called blood sugar) for energy. It comes from the food you eat. Your body breaks down most of that food into glucose and releases it into your bloodstream. If your cells can't get enough glucose, your body breaks down fat for energy instead. This produces an acid called ketones, which can build up in your blood and urine.
Tests
This test measures lactate dehydrogenase (LDH) isoenzymes in a sample of your blood. It's a general test that can help find out if you have tissue damage from disease or injury. It can also help show which organs and other tissues are likely to be damaged. But an LDH isoenzymes test alone cannot diagnose what's causing the damage.
Tests
A lactate dehydrogenase (LDH) test usually measures the level of lactate dehydrogenase (LDH) in a sample of your blood. In certain cases, LDH levels are measured in samples of other body fluids. This includes testing fluid from the spine ( cerebrospinal fluid ), the belly ( peritoneal fluid ), and the chest ( pleural fluid ).
Tests
This test measures the level of lactate, also called lactic acid, in a sample of your blood. In certain cases, cerebrospinal fluid (CSF) may be used. Normally, you have low levels of lactate in your blood and CSF. High levels of lactate may be a sign of a wide variety of medical conditions.
Tests
Legionella is a type of bacteria . When it affects your lungs, it can cause a severe form of pneumonia known as Legionnaires' disease . Legionella tests look for these bacteria in urine, sputum, or in some cases in lung tissue. A blood test may be done to check if you have been exposed to the bacteria, but it cannot diagnose a Legionella infection.
Tests
A lipase test measures the level of lipase in your blood. Lipase helps your body digest fats . It's a type of digestive enzyme. An enzyme is a protein that speeds up certain chemical reactions in your body. Most of your lipase is made in your pancreas, an organ located behind the lower part of your stomach. Lipase is also made in your salivary (spit) glands and in your stomach.
Tests
A lipoprotein (a) test measures the level of lipoprotein (a) in your blood. A high level of lipoprotein (a) may mean you have a high risk for heart disease and stroke .
