A bood test (Gold Top Vacutainer) to measure serum folate levels.
Serum Folate is a measure of the folate in the serum.
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 (folic acid) is important for the normal production of red blood cells and deficiency may cause anaemia. It is also important in the 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.
