Folate (Folic Acid): what this test measures

This test measures the level of folate (vitamin B9) in your blood. Folate is essential for producing and maintaining new cells, particularly during periods of rapid cell division such as pregnancy and growth phases.

Folate (Folic Acid): why this value matters

For women, folate is considered particularly important during reproductive years. It may help support healthy pregnancies, hormonal balance, and red blood cell production. Women planning pregnancy are often advised to ensure adequate folate intake.

Folate (Folic Acid): when is testing worthwhile?

Testing may be considered if you are planning a pregnancy, experiencing symptoms of anaemia, following a restricted diet, or taking medications that may affect folate absorption. Your healthcare provider can recommend when testing is appropriate.

Folate (Folic Acid): symptoms of a high or low value

Low Levels

Some people with low folate levels may experience fatigue, weakness, mouth sores, changes in skin or hair pigmentation, irritability, and shortness of breath. Persistent symptoms should be discussed with a healthcare provider.

High Levels

Very high folate levels are uncommon from diet alone and may sometimes mask a vitamin B12 deficiency. Excess supplementation should be discussed with your healthcare provider to ensure it is appropriate for your situation.

Folate (Folic Acid): what to do about an abnormal value

Female

If Low

Low folate may cause anemia and is critical during pregnancy. Consider folate supplementation (400-800 mcg daily) and increase leafy green vegetables.

If High

High folate may mask B12 deficiency. Ensure adequate B12 levels and reduce supplementation if excessive.

Folate (Folic Acid): lifestyle and this value

Leafy green vegetables, legumes, citrus fruits, and fortified cereals are considered good dietary sources of folate. Cooking may reduce folate content, so including raw vegetables could be beneficial. Discuss supplementation with your healthcare provider if needed.

Folate (Folic Acid): frequently asked questions

What is the difference between folate and folic acid?

Folate is the natural form of vitamin B9 found in foods, while folic acid is the synthetic form used in supplements and fortified foods. Both are converted to the active form in your body, though some individuals may process them differently.

Why is folate important during pregnancy?

Folate is considered essential for proper neural tube development in the early stages of pregnancy. Healthcare providers often recommend supplementation before and during early pregnancy to help reduce the risk of neural tube defects.

Can I get enough folate from my diet alone?

Many people can obtain adequate folate from a varied diet rich in vegetables, legumes, and fruits. However, certain individuals, particularly those planning pregnancy, may benefit from supplementation. Discuss your needs with your healthcare provider.
