Formic Acid, Serum
Use
The Formic Acid test is used to measure the concentration of formic acid in serum. Formic acid is a metabolite of methanol, formaldehyde, and methyl formate among others. This test helps in identifying elevated levels which may indicate metabolic acidosis due to methanol or other exposures. It can also be helpful in assessing exposure in environmental and occupational settings and understanding variations in biological levels due to pregnancy, diet, and nutritional conditions.
Special Instructions
Specimens must be submitted individually for each order; they cannot be shared among multiple orders.
Limitations
Results may be affected by environmental and occupational exposures, diet, nutritional status, and pregnancy. The test does not distinguish between sources of formic acid.
