  • Information


Folate, folic acid or a vitamin B test checks for the serum levels of folate in the blood. Folate is essential in the healthy creation and regulation of your body's red blood cells. A typical folate rate is considered 2.7 to 17 nanograms per milliliter (ng/mL). A result lower than 2.7 ng/ml can mean you have a deficiency. 

Symptoms of a folate deficiency

Abnormally low vitamin B levels is often referred to as anaemia and can lead to unusually large red blood cells that cannot function correctly. A deficiency in folate or vitamin B can display itself with the following symptoms:

  • Fatigue
  • Ulcers
  • Weakness, especially in the muscles
  • Vision problems
  • May cause psychological issues such as depression and confusion
  • Reduce energy levels

Additional Information

Vitamin B12 is an important nutrient that helps keep your red blood cells healthy and your nervous system functioning properly. A lack of vitamin B12 can lead to anaemia and other serious health problems.

The B12 blood test is often recommended for people who have a history of anaemia, nerve damage, or other problems related to vitamin B12 deficiency. It can also help determine if someone is at risk for developing a deficiency.

The folate blood test is often recommended for pregnant women, people who have a history of anaemia, and people who have a history of miscarriage. It can also help determine if someone is at risk for developing a deficiency.

If you are planning to have a B12 blood test, be sure to tell your doctor if you are taking any supplements that contain vitamin B12. This will help ensure that the test results are accurate.

If your blood test results indicate that you have a deficiency, your doctor may recommend that you take supplements or make changes to your diet. Getting enough vitamin B12 is essential for good health, so it's important to follow your doctor's recommendations if you are diagnosed with a deficiency.

Vitamin B12 is found in many foods, including meat, poultry, fish, eggs, and dairy products. It is also added to some breakfast cereals and energy bars. If you are not sure if you are getting enough vitamin B12, talk to your doctor or a registered dietitian. They can help you create a diet that will meet your needs.

A folate blood test is a simple blood test that measures the level of folate in your blood. Folate is a water-soluble vitamin and is found naturally in many foods. It is also known as folic acid or vitamin B9.

Folate is important for the production of red blood cells and for the development of the neural tube. A lack of folate can lead to anaemia and other health problems.

Experts Opinion on Folate Tests

"Folate is an important mineral that can lead to anaemia if levels are low. Low levels may be due to an immune disease or nutritional deficiency but can be easily corrected with tablets."
