Vitamin B9 (Folate) Testing

How to check your Vitamin B9 levels with a home fingerprick blood test kit

What Is A Vitamin B9 Test For?

A Vitamin B9 test is also known as a Folate or Folic Acid test.

The Vitamin B9 (Folate) Test allows you to accurately check your levels of Vitamin B9 in a fingerprick blood sample.

Vitamin B9 (also known as Folate) is an important B vitamin. It helps utilise amino acids which are the building blocks of proteins, in order to form blood cells, tissue and aid cellular repair.

Vitamin B9 must be consumed regularly in the diet - typically from green vegetables and fruits. All pregnant women need increased amounts of folate for proper fetal development.

What If Vitamin B9 Test Levels Are Low?

What If Vitamin B9 Test Levels Are Low?

Vitamin B9 is not stored by the body so deficiencies can occur quite quickly if it is lacking in your diet. Other risk factors can also contribute to a Vitamin B9 deficiency including if you:

  • have a poor overall diet
  • drink too much alcohol
  • are pregnant
  • have certain inherited genetic conditions, or diseases like Chrohn's disease


Vitamin B9 levels can be increased by eating foods rich in vitamin B9 including:

  • animal livers
  • dried nuts like hazelnuts, walnuts, almonds, chestnut etc.
  • green leafy vegetables such as spinach, salads, broccoli etc.
  • eggs
  • seafood

Many breakfast cereals are fortified with B vitamins, and B9 supplements are also available. Taking supplements for 3 - 4 months is usually enough for levels to return to normal.
