Indicator Explainer
Prostaglandin-H2 D-Isomerase
Prostaglandin-H2 D-isomerase (190 aa, ~21 kDa) is encoded by the human PTGDS gene. This protein is involved in the conversion of prostaglandin H2 (PGH2) to prostaglandin D2 (PGD2).
This page explains what the indicator is and how results are interpreted in general terms. Reference ranges depend on the laboratory, the method, and your own situation — no single “normal value” applies to everyone. This page is health information, not a diagnosis. For symptoms, treatment, or urgent concerns, contact a healthcare professional.
