Action 8.7. The Secretary undertook to produce a new version of the SOR
and distribute.
b) There was some discussion about how to interpret the results from the
extended pilot exercise, particularly with regard to the need for a specialist
statistician. The Chairman stated that he would consider the issue of
analysing the results and whether specialist advice should be sought. George
Etherington and Peter van Calsteren mentioned a number of contacts who
might be able to offer advice and undertook to investigate this. The point was
made that the method of analysing the data should be clearly defined by the
time the laboratory measurements from the pilot exercise become available.
Action 8.8. Chairman to formulate an analysis method for the pilot study
results.
Action 8.9. George Etherington and Peter van Calsteren to talk to contacts
regarding interlaboratory analysis
c) There was considerable discussion about how a laboratory which had not
taken part in the pilot study would provide validation of its method when
tendering for the main testing contract.
d) There was further discussion about splitting samples, whether this was
required and where it should be done if needed. Among other things, this
would depend on the findings of the extended pilot exercise.
e) Brigid Rodgers asked what would happen if a veteran was unhappy with his
test result and requested another test. It was generally agreed that should a
veteran request a re-test, this would have to be considered on its individual
merits. Each individual would, of course, be free to have another test at
another laboratory at their own expense.
f) There was also discussion regarding the number of laboratories that would be
involved in the main testing contract. The advantage of using more than one
laboratory would be that some samples could be tested by both laboratories to
provide an intercomparison. Members discussed how samples might be
divided between a number of laboratories. It was generally agreed that each
laboratory would receive batches of say 50 samples i.e. Lab 1 gets 50
samples to test and then Lab 2 get 50 samples.
Post meeting note: The number of laboratories taking part in the testing
programme has been discussed a number of times without resolution. The
Secretary will issue an email canvassing further views on this subject so that a
decision can be made at the next meeting.
Action 8.11. Secretary to email board members regarding the number of labs
to be involved in the main contract.
