Page "Morbidity and Mortality Weekly Report" Paragraph 12

On March 30, 2004, an " MMWR dispatch ", Blood Lead Levels in Residents of Homes with Elevated Lead in Tap Water --- District of Columbia, 2004 was made available on the MMWR web site.

It was then published by CDC as " MMWR Weekly, April 2, 2004 / 53 ( 12 ); 268-270 ".

Its principal author was Mary Jean Brown, who was the head of the lead poisoning branch of CDC.

The report " summarizes the results of the preliminary investigations, which indicated that the elevated water lead levels might have contributed to a small increase in blood lead levels ( BLLs )".

The report describes the background, and the various kinds of blood tests it employed, and explicitly states: " All blood tests were used in this analysis.

" There is no mention at all of any test results not being available, not even in the caveat section, where other potential sources of error are discussed.
