Viapath Service Changes

08/04/2021: We have been experiencing delays with our Procollagen-3 N-Terminal Peptide (P3NP) assay. This is due to a sudden and substantial increase in the volume of P3NP requests we are reciving combined with periodic assay failure. We have a planned program of actions to increase our throughput and capacity. We apologise for any inconvenience caused and would like to reassure you that we will be processing all the remaining samples as soon as possible. For further information please see the attached communication letter that was sent out.

26/04/2021: Please see attached letter that details changes to our current platforms for Haematology & Haemostasis at Denamrk Hill. This is due to an analytical upgrade for our equipment at the Deanmark Hill site. 

13/05/2021: This letter serves to inform users of the delay to vitamins A, E and warfarin turnaround times within the Viapath Analytics Nutristasis Department at St. Thomas’ Hospital, due to analyser breakdown.

15/05/2021: This assay will be moved from the Immunochemistry Laboratory using the Human sTfR Quantikine IVD ELISA Kit (Bio-Techne Brands R&D Systems) to the Roche Cobas 8000 in the Blood Sciences Laboratory, both based at King’s College Hospital (Viapath). This has been done in response to the manufacturer of the previous assay discontinuing it, however this change will mean results will be available the next working day. For further information please see attached letter. 

20/05/2021: We are writing to you to update you/clarify the testing procedure for latent TB infection (LTBI) performed in Clinical Immunology Laboratory at KCH/Viapath. In 2019, the Laboratory introduced the Quantiferon TB Plus (QFT-Plus) test for investigation of LTBI. Prior to the introduction of the QFT-Plus assay, all samples for LTBI investigations were sent to Oxford Diagnostics for the T-SPOT assay. For full details please see attached letter.  

20/05/2021: Please find attached letter clarifying the procedure for requesting and reporting of urgent immunosuppressant results (tacrolimus, cyclosporin, sirolimus and everolimus) by this laboratory at weekends and on bank holidays.

02/06/2021: We want to inform you of some changes to the Levetiracetam service at King’s College Hospital, Denmark Hill. This assay will be moved from the Blood Sciences Laboratory analysed on the Roche, to a sendaway for the Therapeutic Drug Monitoring Unit at the Chalfont Centre for Epilepsy. For further information please see the attached letter. 

05/07/2021: We are contacting you as current users of our androstenedione service at Viapath’s Reference Biochemistry laboratory at King’s College Hospital to notify you of a method change. From 26th July 2021, the method will change from immunoassay to analysis using liquid chromatography-tandem mass spectrometry (LC-MS/MS). For further details please see attache letter. 

22/07/2021: This letter is to provide an update on the Stones Service within the Viapath Analytics Reference Chemistry Department at St. Thomas’ Hospital. The department has been experiencing an increase in demand for the service whilst also managing reduced staffing levels and prioritisation of critical services. This has resulted in delays with the Stones service and an increase in turnaround time

24/08/2021: We are writing to inform you of changes in the cutoff concentrations for reporting selected drugs of abuse analytes. This is to bring our service in line with the current European Workplace Testing Guidelines (EWDTS, 2015). These changes will take effect from 1st September 2021. For full details please see attached letter and further information leaflet.

31/08/2021: Please see attached letter detailing changes to EDTA tube changes at GSTT for GP request in support of the national tube shortages. 

01/09/2021: Please see attached letter detailing changes to EDTA tube changes at Denmark Hill for GP request in support of the national tube shortages.
