Subject:  Discontinued Red blood cell folate order

 

The current Red cell folate level at AMS Laboratory is being discontinued, June 1, 2020. 

According to Ascension’s National Stewardship Standards, Red blood cell folate testing should be retired because it has “limited clinical utility”.   RBC folate measurements demonstrate analytical variation due to pretreatment and analytical issues around hemoglobin, hematocrit and specimen stabilities.   

 We recommend that a Serum Folate be ordered instead of the RBC folate.  Serum folates similarly increase in response to folic acid supplementation and is influenced by fewer analytical variables.  The serum folate also provides an assessment of folate status that is superior to the RBC folate. 

 

Folate, serum is run daily 24/7.   

If you have more questions regarding this change please call Odette Walker, Laboratory Manager at 316-268-5361.
