The laboratories at Cincinnati Children’s Hospital Medical Center perform a variety of genetic, biochemical and functional assays for atypical hemolytic uremic syndrome and thrombotic thrombocytopenic purpura (both familial and acquired forms). 

Physicians do not need to be affiliated with Cincinnati Children's to order tests.

Physicians Ordering Tests 

When ordering tests, physicians must complete and sign the test requisition and enclose it with the sample. All information must be completed before the sample can be processed.
