Stan, et al,
Many years ago, I served in the US Air Force in the Medical Service Corps. My 
job was to manage a clinical laboratory that analyzed blood, urine, and other 
specimens of human origen. The military policy at the time was to conduct 
periodic proficiency testing of laboratories to determine their proficiency.
The results of these proficiency tests were then distributed to all 
participating laboratories so they could ascertain how well they were doing, as 
compared to other laboratoris and known standards. As I recall, the variation of 
results from different laboratories on the same samlples were considerable and 
often at significant variance with the known sample. From this experience, I was 
impressed with the need for surveillance of testing laboratories to assure that 
they were proficient in their analyses. I believe it would be a good policy to 
conduct  periodic proficiency testing  at all clinical laboratories, both 
military and civilian.

Congress passed the Clinical Laboratory Improvement Amendments (CLIA) in
1988 establishing quality standards for all laboratory testing to ensure the
accuracy, reliability and timeliness of patient test results regardless of
where the test was performed.  The Centers for Medicare & Medicaid Services
(CMS) regulates all laboratory testing (except research) performed on humans
in the U.S. through the Clinical Laboratory Improvement Amendments (CLIA).
The objective of the CLIA program is to ensure quality laboratory testing.
CLIA requires all facilities that perform even one test, including waived
tests, on "materials derived from the human body for the purpose of
providing information for the diagnosis, prevention, or treatment of any
disease or impairment of, or the assessment of the health of, human beings"
to meet certain Federal requirements. If a facility performs tests for these
purposes, it is considered a laboratory under CLIA and must apply and obtain
a certificate from the CLIA program that corresponds to the complexity of
tests performed.

FDA 'approval' remains a cloud concept whose origin seems to be unknown.  I
do know that FDA has implemented new quality control regulations concerning
the preparations of all PET nuclides produced by accelerator technology.

Stan, what's the difference between "CLIA certification" and "FDA approval"?

It is my personal opinion that the analysis of excreta material is only a
part of the dose-evaluation process.  As long as the laboratory reporting
the analytical results does not provide a dose estimate, there is no reason
to require FDA 'approval' should it exist.  It should be understood that the
laboratory be required to participate in the appropriate
performance-evaluation programs (i.e., DOELAP, NAVLAP, Oak Ridge, etc.) that
determine ability to provide an acceptable result.  I agree the laboratory
should be CLIA certified. 

Most HP/MDs that provide dose estimates employ computer programs as part of
the process, i.e. IMBA , DCAL, etc.  I know of no program within the FDA
that has the ability to evaluate these codes, or do I know of a program
within FDA that can issue 'approval' to an analytical laboratory to perform
radiobioassay work.  In fact, I know of no program in any form that
evaluates the entire dosimetric assessment process.  One can see a need.
