As a natural water-soluble substance, folic acid is involved in carbon transfer reactions of amino acid metabolism, in addition to purine and pyrimidine synthesis, and is essential for hematopoiesis and red blood cell production. (NCI05)
Tests
The determination of a sub-population of helper follicular T-lymphocytes to a sub-population of helper follicular T-lymphocytes present in a sample. The measurement may be expressed as a ratio or percentage.
Tests
The determination of the amount of formaldehyde in a sample.
Glossary Term
Refers to a process where a sample is preserved with formalin and then embedded into a paraffin block for sectioning.
Indicators
This gene plays a role in the modulation of gene expression.
Indicators
This gene is involved in transcriptional regulation and may play a role in myogenic growth and differentiation.
Glossary Term
A mutation occurring within the protein-coding region of a gene which results in a shift in the reading frame of the encoded protein. Frameshift mutations often result in the premature truncation of a gene product.
Tests
The determination of the amount of free complement C5 present in a sample.
Tests
The determination of the amount of free tau protein present in a sample.
Tests
The determination of the ratio of free testosterone compared to total protein present in a sample. The measurement may be expressed as a ratio or percentage.
