Harnet Material: Submitted Required: Urine and Blood 9-23,26,60 by Dr; Kehoe Lead Analyses O URINE Analysis Number Volume Specific Gravity Mg; Pb/Liter 60A-7189 127 ml. 1,024 0.09 BLOOD Analysis Number Grams Kg. pb/100 Grams 60A-717 Soectrographio Dithizone 18.3 18.7 0.09 0.07 I The concentration of lead in the urine is lower than it has been found to be previously, in probable indication of the reduced level of lead in the tissues. The concentration of lead in the blood is indicated most faithfully by the lower of the two results reported (because of the greater variability of the results of spectrographic analysis). While the concentration in the blood has not subsided as rapidly as might be hoped and expected, it is not at a level which should excite concern at this time considering the symptomatic response of Mr. Avery. Further analyses are Indicated after an Interval of two or three weeks (at the time of obtaining further samples from Mrs. Avery), at which time it is to be expected that a decrease in the concentration in the blood will have occurred. If it has not occurred by that time, consideration should be given to chelative therapy. K i 000844: ) Signed: V A ^-vrv^ . Reported : 9-28-60 Robert A.Kehoe,M.i>
