What Is A Folate Test?
The folate test measures the level of folate (vitamin B9) in the body. Folate is essential for the production of red blood cells, DNA synthesis and proper nerve function. It also plays a critical role during pregnancy, supporting fetal development and preventing neural tube defects.
This test is often done to:
Diagnose folate deficiency, which can lead to anemia and other health issues.
Monitor nutritional status, especially in individuals with conditions affecting absorption, such as celiac disease or Crohn’s disease.
Check folate levels in pregnant women to ensure proper fetal development.
A folate deficiency can result in symptoms such as fatigue, weakness and memory problems. Detecting and addressing low folate levels can prevent complications and improve overall health.
How is the Test Performed?
Folate test requires a blood sample:
Sample Collection
Blood is drawn from the vein of your arm.
Lab Analysis
The sample is analyzed at Genex Lab where folate levels are measured using advanced diagnostic equipment.
Preparation
You may be asked to fast for 6-8 hours before the test to ensure accurate results. Proper instruction will be provided to you when you book the test.
What are the symptoms that prompt this test?
The most common symptoms that prompt this test are:

What are Normal Ranges for This Test?
1 to 17.5 ng/mL (or 7 to 39.7 nmol/L)
Pregnant women may have slightly higher folate levels due to increased diet and supplementation of folic acid which is commonly given during the first trimester.

What Happens if Test Results Show Abnormal Levels?
Low Folate Levels
- May indicate folate deficiency due to poor diet, malabsorption or excessive alcohol use.
- Your doctor may recommend dietary changes, increasing folate-rich foods (e.g. leafy green vegetables, beans, citrus fruits) or taking folic acid supplements.
- Further testing like vitamin B12 test, complete blood count may be ordered to rule out deficiencies or underlying conditions.
High Folate Levels
- Rare condition but may occur due to excessive supplementation or certain medical conditions.
- Your doctor will interpret the results and based on your medical history will adjust supplementation when necessary.
