How come he didn't pee 50 times the normal amount of any other metal?
Because that's the rate for lead.

Why would the NIH use urine collection for any of their research studies if it's so completely meaningless?
I dunno, what are they looking for?

(What's the level in his blood?) I don't know, and I don't care. He didn't eat a lead toy, he's been slowly accumulating for years. It's not in his blood.
By what magic, then, did it get into his pre-chelation pee?

Analysis of lead in whole blood is the most common and accurate method of assessing lead exposure in human. Erythrocyte protoporphyrin (EP) tests can also be used to measure lead exposure, but are not as sensitive at low blood lead levels (<0.2 mg/L). Lead in blood reflects recent exposure. Bone lead measurements are an indicator of cumulative exposure. While measurements of urinary lead levels and hair have been used to assess lead exposure, they are not reliable.

Elevated lead in the body can be detected by the presence of changes in blood cells visible with a microscope and dense lines in the bones of children seen on X-ray. However, the main tool for diagnosis is measurement of the blood lead level; different treatments are used depending on this level.
An x-ray and a drop of blood on a slide. Those are the reliable tests, for decades. Proven, cheap and readily available.

But you prefer pseudoscience. So your evidence is a measurement known to be unreliable and inaccurate; and then you make major mistakes and generous leaps of logic in your interpretation of the results.

Without being rude, I urge you to change your thinking about this. Let's put it this way. If cheap, proven, reliable tests show long-term lead accumulation in your son, a battery of specialists will suddenly turn their attention to improving him. Covered by insurance -- probably using chelation to do it -- and you will be proven right. What do you have to lose?
