It thus is also a biomarker for intracellular levels of folate. The FIGLU test is used to identify vitamin B₁₂ deficiency, folate deficiency, and liver failure or liver disease. [1] [2] It is elevated with folate trapping, where it is accompanied by decreased methylmalonic acid, increased folate and a decrease in homocysteine. [3]
The control line of this pregnancy test is blank, making the test invalid. The control line on the left of this pregnancy test is visible, suggesting that the test result is valid. A pale purple line has also appeared on the right hand side (the test line) which clearly signifies that the subject is pregnant.
Folic acid, which is the synthetic form of the vitamin folate, is critical both in pre- and peri-conception. [7] Deficiencies in folic acid may cause neural tube defects (NTDs). Women who had 0.4 mg of folic acid in their systems due to supplementing 3 months before childbirth significantly reduced the risk of NTDs. [29]
[2] [3] Use in pregnancy or breastfeeding is generally regarded as safe. [2] When used for anemia it is recommended that pernicious anemia as a cause be ruled out first. [3] Folinic acid is a form of folic acid that does not require activation by dihydrofolate reductase to be useful to the body. [3] Folinic acid was first made in 1945. [5]

The un-methylated form, folic acid (vitamin B 9), is a synthetic form of folate, and must undergo enzymatic reduction by dihydrofolate reductase to become biologically active. [1] It is synthesized in the absorptive cells of the small intestine from polyglutamylated dietary folate. It is a methylated derivative of tetrahydrofolate.
The expiration date of pharmaceuticals specifies the date the manufacturer guarantees the full potency and safety of a drug. Most medications continue to be effective and safe for a time after the expiration date. A rare exception is a case of renal tubular acidosis purportedly caused by expired tetracycline. [7]
