P. H. A. meeting you were kind enough to allow us to '..rite you for advice. The present stage of ny lead program consists of only blood leads with no urinary lead determinations at all. I would bo very grateful if you would send me information concerning the type of container, precautions of sampling and interpretations of results, I presume the container should be pyrsx, as are our tubes for blood saiTcles. As vou know, we offer not only A ^agnostic service to small plants, but a laboratory service to t;hhee plant physician- or physician on call. For economy, we send them simple petroff needles with pyrex oxalated tubes, Y/e would like1 to include urine determinations for them as well.
