Reference Range Information
Performing Location Reference Range
​Mayo Medical Laboratories ​ ELISA: Negative: <14 RU/mL
Borderline: > or =14-<20 RU/mL
Positive: > or =20 RU/mL 
 
IFA: Negative
Interpretation
Therapy outcome can be monitored by measuring the anti-phospholipase A2 receptor (PLA2R) antibody titer. A titer increase, decrease, or disappearance generally precedes a change in clinical status. Thus, the determination of the antibody titer has a high predictive value with respect to clinical remission, relapse, or risk assessment after kidney transplantation.
