Tests
The determination of the amount of vanillyl mandelic acid metabolite present in a sample.
Glossary Term
A measure of the variability in a sample or population. It is calculated as the mean squared deviation (MSD) of the individual values from their common mean. In calculating the MSD, the divisor n is commonly used for a population variance and the divisor n-1 for a sample variance.
Glossary Term
The relative rate of occurrence of a specific variant allele compared to the total number of alleles at that locus in the sample. This measurement may be reported as a ratio or percentage.
Indicators
Vascular endothelial growth factor A (232 aa, ~27 kDa) is encoded by the human VEGFA gene. This protein plays a role in both cell proliferation and angiogenesis.
Tests
The determination of the ratio of viable cells to total cells present in a sample. The measurement may be expressed as a ratio or percentage.

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.
