Q: What does it mean if my child's Alkaline Phosphate level is high?
Dear Ms. H' --
Hmm, tough one without more info'. There are 3 liver enzymes we monitor
with routine blood testing to see if there's anything wrong there. Two are
associated with cells busting from toxins like alcohol and some drugs (including
occasionally drugs we're giving). These are the "transaminases",
usually listed as SGOT and SGPT. Then there's Alkaline Phosphatase
(AP). Sometimes that goes up a little when the transaminases do, but if
it's up all by itself, in theory that's supposed to be more associated with
problems in the bile system -- the channels from the liver to the
intestine that carry away waste products the liver has filtered from the blood
However, there are other sources of AP, like bone -- so
you'll have to ask the doctor who ordered the test what she/he was looking for
and what this means.
