Covid-19: Changes to SWLP services
This page provide details of all the changes to the services that South West London Pathology (SWLP) offers, in light of the current Covid-19 pandemic.
All changes to services will be added to this page, so please check the page regularly to confirm which services have been affected.
There are a number of changes to our immunology services.
Faecal alpha-1 antitrypsin
Routine analysis of faecal samples for alpha-1 antitrypsin is not currently being carried out, due to the most recent advice from PHE about the risk of transmission of coronavirus from these samples. Any requests received will be reported with a standard comment explaining why these tests are not being run.
The faecal samples will be stored indefinitely.
If these tests are considered essential for a patient’s care, please call the Immunology Consultants on 020 8725 5106 to discuss whether arrangements can be made to analyse a specific sample.
Tau protein (asialotrasferrin) for suspected CSF leak
The Immunology laboratory is unable to analyse samples for Tau protein (asialotrasferrin) for suspected CSF leak if the sample is taken from the respiratory tract, eg nasal leak, unless the patient is confirmed as being Covid-19 negative. Samples taken from other sites, eg ears or surgical wounds, will be analysed.
Restriction in the collection of cryoprotein samples
Collection of cryoprotein samples at St George’s Hospital is being restricted. If you require collection of a cryoprotein sample, please call the Immunology Consultants on 020 8725 5106 to discuss the case first.
Urine microscopy will now only be performed on the following samples:
- children under six years old
- renal transplant patients (where clearly stated on the request)
- nephrostomy urine (where clearly stated on the request).
