Folic Acid Test
A folic acid test is used to determine the amount of folic acid present in the blood at a specific time. Folate is the general term used for various forms of vitamin B9, including folic acid. Folates can be obtained naturally from numerous food sources, including fruits, vegetables, nuts, beans, peas, dairy products, chicken, meat, seafood, and grains.
Folic acid is also added to vitamin supplements and fortified foods. There is a wide selection of folic acid supplements available in the market. The test is a safe procedure with minimal risks, such as slight bruising at the needle insertion site.
What is the folic acid test used for?
The folic acid test can be used to determine:
- Identify the underlying cause of anaemia.
- Evaluation of malnutrition or difficulties in absorbing folic acid.
- Monitor medication efficacy for treating Vitamin B12 or folic acid deficiency.
- Assess the levels of folic acid in women to prevent certain birth abnormalities and ensure proper foetal development.

Folic acid can be detected by utilizing methods like UV-visible spectroscopy, TLC (Thin Layer Chromatography), and colorimetric reactions with particular reagents such as potassium permanganate or iron (III) chloride.
Why do I need a folic acid test?
If you are experiencing symptoms such as diarrhea, fatigue, constipation, headache, swollen tongue, loss of appetite, numbness, and memory loss, it is advisable to undergo a folic acid test to determine if you have a deficiency in Vitamin B9. These symptoms may indicate a lack of folic acid in the bloodstream, and a proper diagnosis can help in identifying the underlying cause of the health issues.
What happens during a folic acid test?
When you go for a blood test, a healthcare provider will apply an elastic band to the upper arm to limit blood flow to the area. They will then clean the injection site to reduce the risk of infection. To extract the blood sample with minimal discomfort, the healthcare provider carefully draws the blood from the arm. After taking the required amount of blood, the lab technician will remove the needle and place a bandage or cotton wool over the injection site to prevent bleeding and promote healing.
The folic acid test procedure involves a blood test to measure the level of folic acid (vitamin B9) in the blood. This test helps identify deficiencies or excess levels of folate, both of which can impact health.
Procedure:
- Preparation: Typically, no specific preparation is needed, but fasting for 8-12 hours before the test may be advised in certain situations.
- Blood Collection: A healthcare provider will draw a blood sample from a vein, often in the arm, using a needle.
- Lab Analysis: The blood sample is sent to a lab for processing to determine the folate concentration.
- Results: Results usually take a few days. Low folate levels may suggest a deficiency, while high levels could indicate excessive folic acid intake, often from supplements.
This test is commonly used to diagnose folate deficiency, which can lead to symptoms such as fatigue, irritability, anaemia, or birth defects during pregnancy.
What is the normal range for folic acid?
Folic acid levels in the blood should be between 2.7 and 17.0 nanograms per millilitre.

If your folic acid levels are low, it could indicate various health issues, such as dietary deficiencies, or an eating disorder like anorexia nervosa. Additionally, it may be a sign of liver disease, celiac disease, sprue, or Crohn's disease. However, seeking medical advice before making any conclusive diagnosis is important. The doctor will assess the condition and develop an appropriate diagnosis and treatment plan based on the individual needs.
Symptoms of folic acid deficiencies are
- A lack of energy.
- Extreme tiredness.
- Pins and needles (paraesthesia)
- A sore and red tongue.
- Mouth ulcers.
- Muscle weakness.
- Disturbed vision.
- Psychological problems, which may include depression and confusion.
What does a high folic acid test mean?
Having high levels of folic acid in your blood may be a result of consuming a diet rich in folate or taking folic acid supplements or vitamins. However, it's important to note that the recommended upper limit for folic acid intake for adults is 1000 mcg per day. Exceeding this limit may lead to elevated levels of unmetabolized folic acid in the bloodstream. Therefore, it's essential to be mindful of folic acid intake to avoid any potential health risks.
Can folic acid affect pregnancy Tests?
Folic acid is essential for women aiming to get pregnant as it plays a crucial role in preventing birth defects, particularly neural tube defects. Significantly, folic acid does not influence the results of a pregnancy test. Pregnancy tests work by detecting the hormone human chorionic gonadotropin (hCG) in urine, which is not affected by folic acid levels. This means that consuming folic acid while trying to conceive or throughout pregnancy does not affect the accuracy of a home pregnancy test. It is crucial to adhere to the recommended folic acid dosage during pregnancy to promote healthy fetal development.
