In this case-control study of children with PANS and idiopathic OCD and/or tic disorders, abnormal laboratory findings were common in both groups and did not differ significantly. The full set of recommended medical investigations rarely identified underlying somatic conditions in children with PANS. These findings question the clinical utility of the comprehensive and costly medical investigations currently recommended for children with suspected PANS.
Vasiljevic et al. (Fri,) studied this question.
