Expired consumables and reagents
whether blood collection tubes used outside of their manufacturers expiry date can be assumed to be fit for purpose in the absence of validation in a forensic or anti doping analysis?

No. Blood collection tubes used after the manufacturer’s expiry date cannot be considered fit for purpose without appropriate validation or documented justification.
After expiry, there is no confirmation that the tube remains sterile, that the vacuum and closure system remain functional, or that any anticoagulant, preservative or additive present in the tube remains effective and stable. In forensic and anti-doping testing, where sample integrity and evidentiary reliability are critical, the use of expired tubes may compromise the validity of the sample and the defensibility of analytical results. Therefore, expired tubes should not be used unless their suitability for the specific intended purpose has been scientifically demonstrated and documented.
thnak you for this response. Following on from this, the lab in question is continuing to maintain that the tubes can be used. They have not done any validation , nor have they completed any documented justification. They are now attempting to rely on the result for the purposes of an anti doping test and sanction the person for the result. Who can we complain to about this conduct of the lab?
Probably a national institution or a laboratory specialising in diagnostics, biology, or a related field.
