FOLS

Folate is a vital B vitamin needed for energy production, DNA repair, and healthy blood formation. The Serum Folate test measures the level of folate circulating in the blood, reflecting your recent dietary intake. Low levels can cause fatigue, mouth sores, anaemia, and in severe cases, complications during pregnancy.

Why Folate Testing Via Serum Matters?

The Serum Folate test helps identify whether your daily diet provides enough folate. Detecting deficiency early allows for dietary adjustments or supplementation, preventing health problems linked to low folate.
