Pathology standards for confirmed and ?COVID-19 samples

All samples from infected patients can potentially contain the coronavirus (COVID-19) and need to be handled in the laboratory in such a way as to minimise the risk of infection for laboratory staff. It is therefore vital that all samples are labelled and packaged correctly to assist lab staff in identifying high risk samples.

Labelling samples

Please ensure correct specimen type is selected on ICE e.g. nose & throat, sputum, BAL etc…

All confirmed and ?COVID-19 samples should have the high risk sample box ticked on ICE.

Both confirmed and ?COVID-19 samples and forms must be labelled with yellow ‘danger of infection’ stickers.

Danger of Infection labels can be obtained from the print unit-Code WRN502 or from Pathology Supplies
(email leedsth-tr.pathologysupplies@nhs.net).

Packaging samples

All confirmed and ?COVID-19 samples are double-bagged as there is a risk that the samples could leak during transport to the lab. This is an important health and safety issue to protect staff.

Transporting samples

Samples that must be walked/ transported to the lab: (Not sent by POD / airturbe)

  • Nose & throat swabs
  • MRSA screens
  • Any swab for bacterial culture
  • Urine
  • Faeces
  • Sputum
  • Bronchoalveolar lavage (BAL)
  • Nasopharyngeal aspirate (NPA)

Samples that can be sent by POD (airtube):

  • Any blood sample e.g. FBC, U+E, LFT etc.
  • Blood cultures
***REMEMBER: ALL SAMPLES MUST HAVE A DANGER OF INFECTION STICKER AND BE DOUBLE-BAGGED, ONE request label per bag and only listed samples in that bag***
