Important Customer Notice Field Safety Notice

Ref: 2021/1422 ICN Number: 1422

MHRA TBA
NHSSC Ref: 52

Alert:

  • Copan has received some reports of Bordetella parapertussis false positives observed at high cycle threshold values (Ct, Cycle threshold) when combining eSwab® with some in-house PCR protocols and the Pathofinder BV-RealAccurate Quadruplex Bordetella PCR kit.
  • The investigation revealed the presence, inside the eSwab® device, of non-viable Bordetella parapertussis nucleic acid residues derived from raw materials used in the production process. These fragments can potentially be amplified with PCR methods, and in some cases, they could be detectable, giving false-positive results (weak positive at high Ct) depending on the analytical sensitivity of the commercial kit or the in-house protocol used.
  • Since it is not currently possible to exclude the presence inside the eSwab® device of nucleic acid fragments coming from non-viable microorganisms other than Bordetella parapertussis, nor to exclude that these fragments are amplifiable and detectable with the combined use of eSwab® with PCR protocols, Copan considered it appropriate to integrate the instructions for use with a number of warnings and precautions. See our Downloads section to refer Field Safety Notice for full details.
