CellPath VFM Slides and Coverslips


ICN number:119

  • Date:05/07/2017
  • Product area:


  • CellPath Ltd has issued an urgent field safety notice following a reported incident of a rise in crystals being reported in joint fluid.
  • Further investigation revealed that there appeared to be strongly negatively birefringent debris that can sometimes resemble crystals in the current batch of slides / coverslips being used.


  • Some patient samples originally thought to have monosodium urate crystals present were found to be negative on review. These ‘pseudo-crystals were visible when just examining saline and reduced if the slide and coverslip were pre-washed in alcohol.
  • These products are available via NHS Supply Chain as NPC  KTH002 mpc SAH-2222-03 and KTH110 mpc MAE-1000-03P
