Why a dead-clean sterile filter can pass pyrogen straight through
Bacterial endotoxin is a heat-stable lipopolysaccharide from the outer membrane of Gram-negative organisms. It survives sterilisation, passes a sterilising filter, and is…

The health authority in Spain has issued a warning on falsified dulaglutide injection pens found in the legitimate supply chain. The Journal has reviewed the notice and the accompanying photographs; the distinguishing features are a batch-number font difference and a needle-shield colour, neither of which a patient could reasonably be expected to detect.
Comparison of 24 certificates supplied by the reseller against the laboratory’s public archive matched 9 of them to reports commissioned by other parties, in some cases more than a year earlier. The reseller did not respond to two written requests for comment.
The document is the weakest link in this trade. A certificate is a PDF; a laboratory letterhead is an image; a lot number is a string. Nothing in the ordinary transaction allows a buyer to confirm that a given report was issued for a given vial, and the four independent services differ in whether they offer any lookup at all.
Havel Novotný, independent laboratory quality manager, said the underfill finding was the more consequential one. "Nobody is being poisoned by a low content figure. Everybody using that vial is out by a fifth in every calculation they make."
The Journal has referred the cloned document to the laboratory named on it and has asked all four independent services whether they will offer a public report-number lookup. Two have replied.

The report states the gradient, the wavelength and the integration threshold, which is more than most.

The observation that closes a facility is rarely the dramatic one.
Documentation practice is the only part of vendor quality a buyer can assess before purchase.
The header identifies the batch, the table records the tests, and the footer says who is answerable. Two of the three are usually incomplete.
