Folate - Serum

Ordering Information
SERUM FOLATE LEVELS ARE MOST ACCURATE IF PATIENT IS FASTING.
 
Folate levels will no longer be available unless clinical notes indicate specifically that the patient is at risk.
Serum folate (fasting) will be tested preferentially.  Red cell folate testing is not  routinely available.
The clinical indications are either malabsorption (including coeliac disease) or macrocytic anaemia.
Please discuss requests outside of these indications or the need for a red cell folate with a haematologist or haematology registrar by ringing 9496 3100 or 9496 5981.
