The way that H.pylori testing is performed has changed within the Microbiology department. A H.pylori stool antigen test is now in place, and is awaiting UKAS accreditation which will be assessed in January. Therefore users must be aware that this test is currently unaccredited. Tests are accredited to internationally recognised standards for medical laboratories ISO 15189. The previous H.pylori Ab test which utilised patient serum is no longer available.
Additionally, the methods for Cryptococcal antigen detection have changed. Previously, an antigen agglutination test was performed which is now no longer utilised within the department. The department now utilises a lateral flow test which is currently unaccredited: UKAS are assessing the extension to scope in January.
The department has also applied for an extension to scope for CPE testing, to include the chromogenic agar which we utilise and a PCR platform. This means that currently the CPE testing is unaccredited. The extension to scope is being assessed by UKAS in January.
