RESULTS OF BLOOD ANALYSES
A sample of your blood was taken in August for a test program to compare two analytical methods for measuring organic fluorine in blood. The Torch method burns the blood in a special torch and the combustion products are scrubbed
and analyzed for fluorine. It measures organic fluorine plus
inorganic fluorocompounds that burn in the torch. The C-8/GC method measures the C-8 by gas chromatography (GC) which separates the C-8 from other fluorocompounds.
We believe that C-8/GC results are the best
measurements of organic fluorine in blood samples. We plan
to use the C-8/GC method for analyzing blood samples because
it measures C-8 and is less subject to interference than the
Torch method.
.
We are reporting the C-8/GC measurement for your blood sample expressed as ppm organic fluorine. This method gives results about 25% higher than the method used for the 1979 samples. The difference may result from incomplete recovery of organic fluorine in the 1979 analyses.
If you have questions please contact Medical Division.

The recent comparison of Torch and C-8/GC results
for 27 blood samples made at ESL indicated that C-8/GC
results were about 25% above uncorrected Torch results. This
