As I said in my original e-mail, both samples carried
the correct details of the patient and the general
biochemical tests were remarkably similar on both of
them. Therefore we concluded that the samples must
have come from the same patient. Somebody has also
mentioned carry over, which I can't see it as a
problem here when both samples were double checked
neat and diluted on two different immunoassy
platforms.
