The only thing that is clear, Assuming that the sampling and analysis have been even approximately correct, is that the determination of the lead content of the plasma of the blood, bay these methods, provides no useful information relevant to the diagnosis or prognosis in lead poisoning.

Shortly ofter mot arrieie hod gone to the printer, another Bill, also containing amendmenrs to the Lead Based Paint Poisoning Prevention Act was introduced, by number H.R. 3743.

Moreover, these samples of blood could not be expected to yield any useful information on microscopic examination since there are no hematological abnormal1ties in association with tetraethyl lead poisoning.
