What's this test for?

This test is ideal if you're experiencing unexplained fatigue, weakness, or difficulty concentrating that might be related to a vitamin deficiency. It's especially important for pregnant women, people who consume alcohol regularly, or anyone whose diet lacks fresh fruits and vegetables. Many people use this test when they suspect nutritional deficiencies are affecting their energy levels and overall well-being.

How should I prepare for this test?

No biotin: 72 hours

If you're taking high-dose biotin supplements (vitamin B7 or B8), you should stop taking them at least 72 hours before your blood draw, as biotin can interfere with test accuracy. If you're receiving treatment with certain medications like methotrexate or leucovorin, let your healthcare provider know, as these can affect folate test results. Otherwise, no special preparation like fasting is typically required for this test.

What's included in this test?

Folate, Serum

This test measures your serum folate levels, which reveal how much of this essential B vitamin is circulating in your blood. Folate is crucial for making red blood cells, supporting brain and nerve function, and preventing certain birth defects during pregnancy. Low folate can cause fatigue, weakness, irritability, and difficulty concentrating, making this test valuable for identifying hidden nutritional gaps affecting your daily energy and wellness.

What happens after I get my results?
You'll receive detailed doctor notes in simple language explaining what your folate levels mean for your energy, brain function, and overall health. These notes include personalized recommendations like dietary changes, supplement suggestions, or whether you should check other related vitamins like B12. You'll also get the standard lab report and can track your folate levels over time using our trends feature to see how dietary changes or supplementation are working.
Who should consider getting this test?
This test is especially important for pregnant women or those planning to conceive, as folate prevents neural tube defects in developing babies. It's also valuable for people who drink alcohol regularly, have digestive disorders affecting nutrient absorption, follow restrictive diets, or take medications that interfere with folate. Anyone experiencing unexplained fatigue, weakness, or memory issues should consider checking their folate levels.
What symptoms indicate I may need this test?
Common symptoms of low folate include persistent fatigue, weakness, pale skin, shortness of breath, and difficulty concentrating or remembering things. You might also experience irritability, mouth sores, tongue swelling, or premature graying of hair. If you're experiencing these symptoms along with poor diet, digestive issues, or increased alcohol consumption, a folate test can help identify if deficiency is the underlying cause.
How can I naturally increase my folate levels?
The best way to boost folate naturally is by eating more folate-rich foods like leafy green vegetables (spinach, kale, romaine lettuce), legumes (lentils, beans, peas), asparagus, broccoli, and citrus fruits. Many grain products are fortified with folic acid, which can help too. Since folate can be destroyed by heat, try to include some raw or lightly cooked vegetables in your diet, and limit alcohol consumption as it interferes with folate absorption.
What is folate and why does it matter?
Folate, also called vitamin B9, is an essential nutrient that your body needs to make new cells, produce DNA, and create red blood cells that carry oxygen throughout your body. It's especially critical for brain function, nerve health, and during pregnancy for proper fetal development. Unlike some nutrients your body can store, folate needs to be replenished regularly through diet, making deficiency fairly common in people with poor nutrition.
What does low folate mean?
Low folate levels indicate your body doesn't have enough of this essential B vitamin, which can lead to anemia, fatigue, and impaired cell production. This deficiency is often caused by poor diet, excessive alcohol use, digestive disorders, or certain medications. It can also sometimes be secondary to vitamin B12 deficiency, which affects how your cells absorb and use folate, so your doctor may recommend testing B12 as well.
How often should I retest my folate levels?
If your folate is low and you start taking supplements or making dietary changes, retesting in 8-12 weeks helps confirm your levels are improving. For pregnant women or those with chronic conditions affecting absorption, your doctor may recommend testing every few months. Once your levels are stable and optimal, annual testing is usually sufficient unless you experience symptoms or major dietary changes.

What this means

Your folate levels are below the optimal range, which may explain symptoms like fatigue, weakness, or difficulty concentrating. While not severely deficient, this level suggests your body isn't getting enough of this essential B vitamin to function at its best, and addressing it can significantly improve your energy and well-being.

* Regular blood test results (e.g., CBC) typically start arriving the next business day after sample collection. More complex tests, such as hormone panels, may take up to 10–15 business days due to their complexity.
