Red Cell Folate Blood Test

Red Cell Folate Blood Test

Last updated: 29 November 2017

What is red cell folate?

Red cell folate (RCF) is a measure of the body’s store of the vitamin, folate - also known as folic acid.

How an RCF blood test performed?

The red cell folate (or RBC folate) is a blood test which requires a few millilitres of blood from a vein.

When would you need an RCF blood test?

An RCF may be requested by your doctor if you have anaemia (low blood count), particularly of the macrocytic variety, where the red blood cells are increased in size. Anaemia tends to cause paleness of the skin, tiredness, decreased energy, shortness of breath on minimal exertion, and postural light-headedness or faintness when standing up.

RCF blood test results explained

A low RCF level means a deficiency of the vitamin folate (folic acid). Folate is important for the normal production of red blood cells, and in prevention of neural tube defects such as spina bifida, in the unborn babies of pregnant women.
