PLA2A – “Phospholipase A2 Receptor AB, S” replaced by PMND1 – “Primary Membranous Nephropathy Diagnostic Cascade, Serum”

Testing Algorithm
The phospholipase A2 receptor (PLA2R) enzyme-linked immunosorbent assay (ELISA) is initially
performed. [3800289]

If the PLA2R ELISA result [3800289] is less than 20, then the PLA2R immunofluorescence testing
will be performed at an additional charge. [3800290]

If the PLA2R immunofluorescence result [3800290] is Negative, thrombospondin type-1 domaincontaining 7A (THSD7A) antibody testing [3800291] will be performed at an additional charge.

If not performed, [3800290] and [3800291] will be reported as “TNP”.
