Tests
A vitamin E test measures the amount of vitamin E in your blood. Vitamin E (also known as tocopherol or alpha-tocopherol) is a nutrient that is found in every cell of your body. It helps your nerves and muscles work well, prevents blood clots, and boosts your immune system so it can fight off infections from germs .
Indicators
The term "vitamin K" refers to a group of chemically similar fat-soluble compounds called naphthoquinones: vitamin K1 (phytonadione) is found in plants and is the primary source of vitamin K for humans through dietary consumption, vitamin K2 compounds (menaquinones) are made by bacteria in the human gut, and vitamin K3 (menadione) is a water-soluble preparation available for adults only. Vitamin K is necessary for the liver to produce the coagulation factors II, VII, IX, and X, as well as the clotting factors protein C, protein S, and protein Z; vitamin K deficiency can result in deficiencies of these coagulation factors and excess bleeding. An injection of vitamin K is routinely given to newborn infants to prevent vitamin K deficiency bleeding, also known as hemorrhagic disease of the newborn. Vitamin K deficiency is rare in adults but may result from chronic malnutrition or an inability to absorb dietary vitamins.
Indicators
von Willebrand factor (2813 aa, ~309 kDa) is encoded by the human VWF gene. This protein is involved in platelet adhesion and blood coagulation.
Indicators
WAP four-disulfide core domain protein 2 (124 aa, ~13 kDa) is encoded by the human WFDC2 gene. This protein may play a role in both proteinase inhibition and spermatogenesis.
Tests
Blood tests are used to measure or look at cells, chemicals, proteins, or other substances in your blood . Blood testing, also known as blood work, is one of the most common types of lab tests. Blood work is often included as part of a regular checkup . Blood tests are also used to:
Tests
This test looks for white blood cells in a sample of your stool (poop). White blood cells are also called leukocytes, so this test is sometimes called a leukocytes in stool test.
Tests
A white blood count measures the number of white blood cells (WBCs) in your blood. White blood cells, also called leukocytes, are part of your immune system . They are a type of blood cell made in your bone marrow and found in your blood and lymph tissue (part of your immune system). If you are injured or get sick, the white blood cells will travel through your bloodstream and tissues to where they are needed. There, they will help your body fight off infections and other diseases.
Glossary Term
A procedure that can determine the DNA sequence for nearly the entire genome of an individual.
Indicators
This gene plays a role in regulation of transcription. It is involved in the control of both cell differentiation and proliferation.
Indicators
This gene plays a role in the regulation of nuclear export.
Tests
Xylose, also known as D-xylose, is a type of sugar ( carbohydrate ) that is normally easily absorbed by your intestines. A xylose test checks the level of xylose in both your blood and urine to see how well you absorb carbohydrates.
Glossary Term
A method for converting an individual score into a standard form. The z-score indicates how far and in what direction an item deviates from its distribution's mean, expressed in units of standard deviation. Calculation of a z-score requires knowledge about the population's standard deviation and mean.
