Bluecrest crestVitamin B9 (Folic Acid) Home Test Kit


Vitamin B9 is commonly known as folate or folic acid, and plays an important role in the formation of DNA, as well as maintaining healthy blood cells and nerves. A deficiency in this vitamin can cause the body to make abnormally large and malfunctioning red blood cells (megaloblastic anaemia). This can happen after a few weeks of folate deficiency, and can result in tiredness and weakness.

What we test

  • Folate (Vitamin B9/Folic Acid)
    Folate is a type of B vitamin, also called vitamin B9 or Folic Acid. It helps your body with creating red blood cells, repairing cells and forming DNA. If left untreated, folate deficiency may result in folate deficiency anaemia. It is especially important during pregnancy for foetal development.

Who is this test for?

  • Anyone who wants to check their B9 levels
    This test can check that your folate level is in the expected range and you are getting enough vitamin B9 in your diet. Increased risk factors such as pregnancy, digestive disorders that interrupt absorption, excessive alcohol consumption or genetic factors can impact your folate levels.
  • If you are pregnant
    Folic acid supplements are also advised during pregnancy as it is an important nutrient for foetal development. This test can show whether your level is staying in the expected range.

What are the symptoms of vitamin B9 deficiency?

It should be possible for most adults to get enough vitamin B9 through their diet, but sometimes it is not the case.

Signs of deficiency can include:

  • Tiredness
  • Pins and needles
  • Muscle weakness
  • Mouth ulcers
  • Memory problems

What our Chief Medical Officer has to say

As Chief Medical Officer of Bluecrest, Dr Toby Donati oversees clinical operations, leads on quality improvement and assists the MD with CQC and regulatory compliance. Here’s what he has to say about our Vitamin B9 test:

Vitamin B9, or folate, is a water-soluble vitamin found in many foods including leafy green vegetables, whole grains and beans. Folic acid is the synthetic version, used as a supplement or found in fortified foods.

Most people are able to maintain healthy levels through diet alone but sometimes a deficiency can occur with or without symptoms. It’s important for everyone to get enough vitamin B9 to support red blood cells and DNA development. Folate deficiency may result in folate deficiency anaemia.

Our home vitamin B9 test kits are a highly convenient option to test your folate level at home by measuring the level of folate in the blood. If a deficiency was found it is usually easily treated by dietary changes and/or supplementation.

Frequently Asked Questions

  • Why take a folate test?

    A vitamin B9 test is taken to assess whether a person is suffering from folate deficiency. Symptoms of folate deficiency are varied, and may include the following:

    • Tiredness
    • Pins and needles
    • Muscle weakness
    • Mouth ulcers
    • Memory problems

    However, it is important to note that many people who have a folate deficiency do not experience symptoms. Folate deficiency can affect people of all ages, although it is more commonly seen in older people.

  • How do you prepare for a vitamin 9 blood test?

    There is minimal preparation required with a Bluecrest vitamin B9 home test kit. You can continue to eat and drink as normal beforehand. Full preparation instruction will be disclosed in your confirmation email once you buy your home test kit online.

  • What is the difference between vitamin B12 and B9?

    Vitamin B9, also known as folate or folic acid, is often grouped with vitamin B12 as they both play an important role in keeping the blood and nervous system healthy. Vitamin B9 also has an important role in reducing the risk of certain birth defects such as spina bifida.

    Because of the relationship between vitamins B9 and B12 it is usual to test the levels of both of them together at the same time. This is also usually done in combination with a blood test to look at the red blood cells themselves.

  • What is a vitamin B9 deficiency test normal reading?

    The normal level of vitamin B9 varies between laboratories but as a guide it is above around 4.5μg/L. Levels that are lower than this may indicate a deficiency, and your doctor may need to undertake additional tests to assess whether this is the case.

    Treating someone for vitamin B9 deficiency, without treating a vitamin B12 deficiency they also have, can cause neurological damage. Therefore it is essential that you do not try to diagnose the cause of any vitamin B9 deficiency yourself or try to treat it.

  • What do vitamin B9 blood test results mean?

    It is possible to have low folate levels without a clinical issue. However, your GP may need to undertake further testing to rule out the following potential issues including:

    • Poor diet – a deficiency can be caused by a diet lacking B12 and B9. This is particularly common for people following a strict vegetarian or vegan diet, or those not eating a balanced diet including plenty of vegetables. This can easily be rectified with a better meal plan and / or supplements.
    • Digestive disorders – your digestive system may not be absorbing folate properly.
    • Blood conditions – certain blood conditions such as sickle cell anaemia or spherocytosis mean your body needs more folate than normal and can result in a folate deficiency.
    • Liver damage – such as from drinking too much alcohol.
  • How can I maintain a healthy vitamin B9 level?

    Maintaining a healthy, balanced diet is essential to avoiding deficiencies and maintaining good health in general.  Most people can get the amount of folate they need through eating a healthy balanced diet.  Folate can be found in small amounts in many different foods including:

    • Brussel sprouts
    • Broccoli
    • Leafy greens
    • Chickpeas, peas and kidney beans
    • Fortified breakfast cereals
    • Liver (to be avoided during pregnancy)
