Okay, so we ran the porphyrin test thru Lab Corp. It all came
back negative and it even came back as low in the coproporphyrins.
(result was 5, rr 15-75) Should I assume it was mishandled, or do I
need to rethink my son's mercury status? (we will start chelation
next week) He has no mercury on hair/blood/urine, but high levels of
just about everything else on hair--aluminum, arsenic, antimony, etc,
plus his hair minerals are a holy mess. He meets and exceeds all 3
counting rules by far. He is 5.

I read Andy's posts on how the sample should be handled. They
did give us a light-proof container, but I have no idea if
preservative was added. This same lab has screwed up several other
very basic tests for us before, so I wouldn't be surprised. Also,
they did not measure his creatinine that I can see.

I was looking forward to getting a big fat positive so I could
say
SEE-- THERE'S THE MERCURY!!! For all the people who think I'm nuts
(and for myself , I must admit)

Anyone else get a negative porphyrin but still get mercury out?
Or know anything about LabCorps accuracy with this test??

thanks, Becky
