Double Blind Testing

0:21 …As to why ICPMS I am sure must be very easily available in the west… like a country like the US I am sure almost every university will have it why not do it there?  And if you did get something abnormal will NAA why did you not get it retested with ICPMS or ICPAES ?  I would have done that.  Because especially when you get some unexpected result, so many times the normal.. you are saying 40 times or something…in cadmium.. there are a lot of factors that can make that possible yet that person many not be actually poisoned with cadmium at all.  In other words there are a lot of false positives in metal analysis. And we need to be very careful when we interpret and we need to screen out all those false positives before we jump to the conclusion that there is some significance to this result

0:55 With the numbers so high would it be possible for a person to live so long and die a natural death?

What I said earlier… How is it that you have such abnormally high levels you are not only surprised but flabbergasted?  How is it a person survive with such a concentration in his system?  So  you should have as a toxicologist have it done a second time.   We do it as a routine in our laboratory…at all toxicology laboratories regardless of the analysis have a policy of double testing. When it comes with an unexpected result or when it comes with an unexpected concentration of something.  We have to double test that is a process of accreditation. so if it is an accredited laboratory double testing should have been done, and preferably the 2nd test should not have been done by the same laboratory, but by another accredited laboratory where I told you the thing should have been blind. 

2:00 In saying that we are sending you a sample and we would like you to analyze and tell us…what did you get from this?  You can even provide a clue.. as to what they should be testing. like for heavy metals or whatever it is,  or that this from this person who had this kind of manifestation so you please tell us whether there is something in this or not.  If that second report also comes as in this case with cadmium very high positive it is significant, but I don’t find double testing has been done, I don’t find that a second laboratory was involved,

2:30 I am not sure anything of that sort has been done, so again I am not very convinced that this is actually reflective of high concentration of cadmium of this kind of person’s body which contributed to his death.   Was it an incidental finding, was it a finding of contamination, was it from some other factor?  These are hear to be elucidated,

4) How is it that you have such abnormally high levels (of cadmium) and you are not only surprised but flabbergasted?  How is it a person survive with such a concentration in his system?…   Double testing should have been done, and preferably the 2nd test should not have been done by the same laboratory, but by another accredited laboratory where I told you the thing should have been blind. … I don’t find that a second laboratory was involved, … I am not very convinced that this is actually reflective of high concentration of cadmium of this kind of person’s body which contributed to his death.
