The words this week I want to define are alkaline phosphatase.
Alkaline phosphatase (ALP) is an enzyme that is released by the bile ducts cells ( among other organs). The release of ALP is a marker of stress or injury. So the more injury or stress to the bile duct cells, the higher level of ALP is seen. It is used as a marker of the disease statis and when to begin treatment with Urso. Certainly the lower the number the better. Right now, as of 2023, the ideal targets are under 217. Hopefully in the near future the target number will be under 130.
An elevated ALP can also, as I mentioned, come from other sources - like bone. We will discuss this as well in the future Wednesday posts.
