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.
