A bood test (Purple Top Vacutainer) to measure red cell folate levels.
Red Cell Folate (RBC Folate) is a measure of the body’s store of the vitamin Folate also known as Folic Acid.
Folate is a water-soluble vitamin, which means you need it in your diet every day because it can’t be stored in the body.
Folate is important for the normal production of red blood cells, and in prevention of neural tube defects such as spina bifida in unborn babies.
Folate is found in small amounts in many foods. Good sources include broccoli, Brussels sprouts, asparagus, peas, chickpeas and brown rice. Other useful sources include fortified breakfast cereals, some bread and some fruit (such as oranges and bananas).
Most people should be able to get the amount they need by eating a varied and balanced diet with plenty of green leafy vegetables.
