Tests
A blood test done near the end of the first trimester of pregnancy to screen for common chromosomal defects. This test screens for blood levels of both free beta-human chorionic gonadotrophin (beta-hCG) and pregnancy-associated plasma protein A (PAPP-A) and can detect trisomies of chromosomes 21 (Down's syndrome), chromosome 18 (Edward's syndrome), and chromosome 13 (Patau's syndrome).

Indicators
A fibrillar protein present in blood plasma; it converts to fibrin during the process of blood clot formation.
Tests
A free light chains test measures the level of free light chains in your blood. Light chains are proteins made by plasma cells, a type of white blood cell. Light chains usually link up with other proteins called heavy chains. Together, the light and heavy chains make immunoglobulins, also called antibodies. Antibodies are proteins that your immune system makes to fight germs such as viruses and bacteria .
Tests
This test measures the amount of glucagon in your blood. Glucagon is a hormone made by your pancreas. Hormones are chemical messengers in your bloodstream that control the actions of certain cells or organs. Glucagon works with other hormones, like insulin, to help maintain your body's level of blood glucose , also called blood sugar. Glucagon increases your blood glucose levels, while insulin decreases your blood glucose levels.
Tests
A hematocrit test is a blood test that measures the amount (percent) of your blood that is made up of red blood cells. Red blood cells carry oxygen from your lungs to the rest of your body. The other parts of your blood include white blood cells (to help fight infection and other diseases), platelets (to help make blood clots to stop bleeding ), and a liquid called plasma.
