Regan isoenzyme has the same properties as alkaline phosphatase originating in the:

Explanation:
Alkaline phosphatase has several tissue-specific isoenzymes, and the Regan isoenzyme is the placental form. That means its origin and properties match placental alkaline phosphatase rather than the bone, liver, intestine, or kidney isoenzymes. Clinically, detecting the Regan (placental) isoenzyme points to placental tissue—such as pregnancy or placental tumors like choriocarcinoma or certain germ cell tumors—rather than bone or liver sources. So the Regan isoenzyme is best understood as originating from the placenta.
