Interpretation
Therapy outcome can be monitored by measuring the anti-phospholipase A2 receptor 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.
