And you can do all that and still come out with a false negative, Some

folks show nothing at all until they start chelation............and even if it

does show stuff you can;t do much about it until you have the fillings out

so I would save your money for that

maybe Metametrix because I prepare the aliquot myself so i would know not to

We did the Labbio test for my 3 kids. I collected the kids' first-morning urine

using an opaque cup in a dark bathroom (no window but there was some light from

a window outside the door), and had pre-labeled the sample tube so I could put

it into the UV bag right away. It then went right into the padded mailer

envelope and got sent off. We got moderate to 'remarkable' porphyrin readings,

no false negative. But I have heard of several false negative reports from

friends.

I agree it's not an essential test and the danger is that it convinces parents

not to chelate when in fact there are gains to be had.
