Folate (serum)

The Architect folate assay is a chemiluminescent microparticle folate binding protein assay for the quantitative determination of folate
Clinical details: 
Folates (vitamin B9) serve as cofactors in the enzymatic transfer of single carbon units in a variety of metabolic pathways. Folates are necessary for nucleic acid and mitochondrial protein synthesis, amino acid metabolism, and other cellular processes that involve single carbon transfers. Folate deficiency can be caused by low dietary intake, malabsorption due to gastrointestinal diseases, inadequate utilization due to enzyme deficiencies of folate antagonist therapy, drugs, and excessive folate demand, such as during pregnancy. Low serum folate levels reflect the first stage of folate negative balance, and can precede tissue depletion.
