Glossary Term
A study that compares two groups of people: those with the disease or condition under study (cases) and a very similar group of people who do not have the disease or condition (controls). Researchers study the medical and lifestyle histories of the people in each group to learn what factors may be associated with the disease or condition. For example, one group may have been exposed to a particular substance that the other was not. Also called retrospective study.

Tests
This test looks for CCP (cyclic citrullinated peptide) antibodies in your blood. CCP antibodies, also called anti-CCP antibodies, are a type of antibody called autoantibodies. Antibodies and autoantibodies are proteins made by the immune system :

A CD4 count is a blood test that measures the number of CD4 cells in a sample of your blood. CD4 cells are a type of white blood cell that circulates throughout the body in the blood. They're also called CD4 T lymphocytes or "helper T cells." That's because they help fight infection by triggering your immune system to destroy viruses, bacteria, and other germs that may make you sick.

A celiac disease screening is a blood test that looks for signs that you may have celiac disease , an autoimmune disorder that causes a serious allergic reaction to gluten. Gluten is a protein found in wheat, barley, rye and other grains. It may also be found in other products like vitamins and supplements , hair and skin products, toothpaste, and lip balm.

Glossary Term
A process where a rotating machine exposes a specimen to centrifugal force. This process can be used to remove moisture from a specimen, to subject an organism to increased gravitational forces, or to separate the components of heterogeneous mixtures based on density differences.

Tests
A cerebrospinal fluid (CSF) analysis tests a sample of your CSF for diseases that affect the brain and spinal cord, which make up your central nervous system. Your central nervous system controls and coordinates everything you do, including your ability to move, breathe, see, think, and more.

Tests
A ceruloplasmin test measures the amount of ceruloplasmin in a sample of your blood. Your liver makes ceruloplasmin by attaching copper to a protein. Your liver releases the ceruloplasmin into your bloodstream so it can carry copper to the parts of your body that need it.

Glossary Term
Chi-square test is a statistical test for testing the null hypothesis that the distribution of a discrete random variable coincides with a given distribution. It is one of the most popular goodness-of-fit tests.

Tests
A chloride blood test measures the amount of chloride in your blood. Chloride is a type of electrolyte. Electrolytes are electrically charged minerals that help control the amount of fluids and the balance of acids and bases (pH balance) in your body. You have electrolytes in your blood, urine, tissues, and other body fluids.

Indicators
A chlorine anion that forms the negatively charged part of certain salts, including sodium and hydrogen chloride salts, and is an essential electrolyte located in all body fluids responsible for maintaining acid/base balance, transmitting nerve impulses and regulating fluid in and out of cells.
Indicators
An animal sterol found in the body tissues (and blood plasma) of vertebrates. It can be found in large concentrations within the liver, spinal cord, and brain. Cholesterol is an important component of the membranes of cells, providing stability. It is the major precursor for the synthesis of vitamin D, of the various steroid hormones, including cortisol, cortisone, and aldosterone in the adrenal glands, and of the sex hormones progesterone, estrogen, and testosterone. Cholesterol also has an important role for the brain synapses as well as in the immune system. In conditions featuring elevated low density lipoproteins (LDL), cholesterol often forms plaque deposits in the walls of arteries, a condition known as atherosclerosis, which is a major contributor to coronary heart disease and other forms of cardiovascular disease.
