Tests
A cholesterol test is a blood test that measures the amount of cholesterol and triglycerides (a type of fat) in your blood. Cholesterol is a waxy, fat-like substance that's found in your blood and every cell of your body. Your body needs some cholesterol to make hormones , vitamin D , and substances that help you digest foods.
Indicators
Cholinesterase (602 aa, ~68 kDa) is encoded by the human BCHE gene. This protein plays a role in choline metabolism.
Tests
This test measures the amount of chymotrypsin in a stool (poop) sample. Chymotrypsin is an enzyme, a protein that speeds up certain chemical reactions in your body. It is released by your pancreas (an organ behind your stomach) to help break down the protein in your food during digestion. If your pancreas is working as it should, there will be some chymotrypsin in your stool sample.
Glossary Term
Neoplasm-derived DNA fragments found in the bloodstream or other bodily fluids that have been released from cells.

Tests
Coagulation factors are proteins in your blood. They help form blood clots to stop bleeding when you have an injury. These proteins are also called clotting factors. You have several different types of clotting factors that are all important for making blood clots.
Glossary Term
The ratio of standard deviation to mean, expressed as a percentage or fraction.
Glossary Term
A research study that compares a particular outcome (such as lung cancer) in groups of individuals who are alike in many ways but differ by a certain characteristic (for example, female nurses who smoke compared with those who do not smoke).
Article

Tests
A complement blood test measures the levels and/or activity of a group of proteins that are part of the complement system. This system "complements" or enhances your body's defenses against infections and other diseases. Your immune system makes antibodies, which are proteins to fight disease-causing substances like viruses and bacteria. The proteins in the complement system will also help fight the infection or disease. These proteins work together in a sequence, with one protein activating the next.
Indicators
Complement C3 (1663 aa, ~187 kDa) is encoded by the human C3 gene. This protein plays a role in complement-mediated immunity.
