Hi Helmut

❝ ❝ One subject TCA show positive in the test. In this situation what should we do test again or exclude? if test again, what's the interval is proper?

❝

❝ If a positive result is part of the exclusion criteria – exclude the subject. Otherwise, why did you test for it and state it in the protocol? BTW, I never saw a protocol which allows retesting. Given the half-lives of TCAs likely you will get another positive result anyway.

You mean no retesting in drug abuse or other clinic exam also? I saw hematology can be retested.
TCA isn't listed in protocol, but can be test out in our drug abuse test card. So here is a pratical operated problem. The protocol writer didn't combine the reality with protocol. So all the things just refer to the protocol, then ignore the positive result of TCA?
