Discontinuation of Tests MET22 and MET25, Folate Receptor Antibody Assay, in Plasma/Serum and CSF

Due to a manufacturer reagent change, MNG will discontinue testing for Folate Receptor Antibodies.
Alternative diagnostic testing is available at MNG for cerebral folate deficiency, characterized by a lack of B-vitamin folate (vitamin B-9) in the brain; see 5-methyltetrahydrofolate analysis in CSF (NC01) and FOLR1 gene sequencing (MOL166).
MNG will discontinue MET22 in plasma/serum and MET25 in CSF; testing will not be performed on samples received after October 31, 2019.
