I recently had a set of "health screening" {*filter*} tests through work.  All the
tests (CBC, {*filter*} chemistry, LDL and HDL) came out in the normal range, except
for one test, alkaline phosphatase, where I had a "score" of 144 compared to
a normal range of 30-128.

I'm taking tetracycline, so I looged on the Medline through CompuServe and
looked up the intersection of alkaline phosphatase and tetracycline.  There
are some articles on the topic, but the abstracts aren't available online.

I'll be seeing my doctor next month, and will ask him about it, but can anyone
on the net supply information?  Is this a bad sign, or just a normal reaction?
Are there side effects of having high levels of this chemical?  I've noticed
that my right hand (finger joints) and left ankle have been feeling sorta
creaky recently.  Any relationship there?
