What is a Folate test?
A folate test
helps to see folate levels in the liquid part of your blood, known as serum or red blood cells. Folate is the natural type of vitamin B-9 that has vital functions in the body. It plays several roles, such as
- Developing DNA, a unique genetic code present in all cells of a person.
- Production of red blood cells that carries oxygen throughout the body.
- Help to make, utilize, and decompose protein.
- Growing tissues and cells in the body.
- Increases cells in babies during pregnancy
- Help to protect from changes in the cells that may result in cancer.
Folate is a water-soluble nutrient. If you take large amounts of folate, it will be released from your body through urine. A low folate level or folate deficiency may result in anemia and other diseases. Low folate levels may lead to brain or spine disorders in the fetus during pregnancy.
What is the purpose of this test?
A folate test
measures the healthy folate levels in your body. This test identifies and monitors the condition if you experience a deficiency of folate. Your provider may suggest this test after an abnormal blood test. You may also need this test if you have megaloblastic anemia. A type of anemia in which your body cannot produce enough red blood cells. A folate serum test is a routine test for people having inflammatory bowel disease. It is because they cannot digest nutrients from foods that contain folate.
When do I need a folate test?

There are two methods available to measure folate levels in a blood sample. One of the general methods is to see folate levels in serum. The second method observes the folate levels in the red blood cell, a component of your blood.
The recommended range for the folate serum, or blood plasma
, is from 2.5 to 20 nanograms per milliliter or 4.5 to 45.3 nanomoles per liter (nmol/L). The recommended values for red blood cells are 140 to 628 ng/mL or 317 to 1,422 nmol/L.
Low folate levels
than recommended can indicate a deficiency of folate. Your healthcare provider gives your folic acid supplements. The folate deficiency will disappear within a short time when you take supplements. You can set an online appointment
with a doctor to discuss the quantity of folate you need. The folate values depend on your age and if you are pregnant or breastfeeding.
Low folate levels
may generally occur due to several problems, such as
- Low white blood cells levels
- Low platelets
- Defects in the birth during pregnancy
High folate levels in your body do not indicate any problems. Excess folate will excrete from the body through urine.
The folate test results depend on age, gender, medical history, and other factors. The test results may differ slightly among laboratories. It is because each lab may use different methods for examination.
