High values may indicate

High folate levels are usually not harmful but may mask vitamin B12 deficiency. Very high levels from supplementation may be associated with certain health concerns under investigation.

Low values may indicate

Low folate levels may indicate folate deficiency anemia, poor dietary intake, malabsorption, alcoholism, or pregnancy-related depletion. Deficiency during pregnancy increases the risk of neural tube defects.
