Tests
The determination of the number of the transitional 3 B-lymphocytes in a sample.
Tests
The determination of a sub-population of transitional B-lymphocytes in a sample.
Tests
The determination of the ratio of transitional B-lymphocytes compared to B-lymphocytes present in a sample.
Tests
The determination of the ratio of the IgM+ class-switched unconventional memory B-lymphocytes to total class-switched unconventional memory B-lymphocytes present in a sample. The measurement may be expressed as a ratio or percentage.

Tests
A vitamin B test measures the amount of one or more B vitamins in your blood or urine (pee). B vitamins are nutrients that your body needs to work well and stay healthy. There are eight different types. All together, they are called the “B vitamin complex.”
Indicators
A group of water-soluble vitamins essential for metabolism and normal physiological functions. B6 vitamins, including pyridoxine, pyridoxal, and pyridoxamine, are converted in vivo to pyridoxal phosphate, a cofactor necessary for the synthesis of amino acids, neurotransmitters, and sphingolipids. More than 100 enzymes involved in protein metabolism require vitamin B6 as a cofactor. Vitamin B6 is essential to red blood cell, nervous system, and immune systems functions and helps maintain normal blood glucose levels. Vitamin B6 is found in a wide variety of foods including cereals, beans, meat, poultry, fish, and some fruits and vegetables. (NCI04)
Tests
The determination of the amount of the apolipoprotein B in the very low density lipoprotein fraction of a biological specimen.
