Phospholipase A2 Receptor, Immunofluorescence

Abbrev Code:MMMISC   
Order Code:LAB4909Order Name:Laboratory Miscellaneous Order
Order Instructions:Can be used in conjunction with a quantitative ELISA (LAB8270) to confirm a positive result, especially for a low-level titer. Since the IFA is more sensitive, it can also be used to detect/follow patients with low level antibodies not detected by ELISA.
Synonyms:PLA2R; Anti-PLA2R
Methodology:Indirect Immunofluorescence Assay (IFA)
CPT Codes: 86255 x1
Turnaround Time:Specimens sent to reference laboratory Monday-Friday; results are reported within 8 days.

This test was developed and its performance characteristics determined by Laboratory Medicine and Pathology, Mayo Clinic. This test has not been cleared by the U.S. Food and Drug Administration.

Referral Lab number:PLA2I


Reference Range:Negative
Limitations:Absence of circulating anti-phospholipase A2 receptor autoantibodies does not rule out a diagnosis of primary MN.

Screening for anti-PLA2R antibodies.
Monitoring patients with membranous nephropathy at very low antibody titers.
