We recognise that there are increasing numbers of patients are presenting to the GP Practice after having bloods that they self request/arrange through private providers and this is having an impact on workload. The BMA released this https://www.bma.org.uk/bma-media-centre/high-street-blood-tests-that-pile-pressure-on-nhs-are-a-real-concern-for-gps-says-bma and we have raised this with GPC Wales recently, after discussions from LMC members across Wales DPLMC advises the following:
Should a patient present with concerns over an abnormal self initiated test, it is recommended that it is dealt with as would be clinically appropriate as part of unified/ essential services to follow this up. There is no requirement for a patient to find a private provider to interpret the results. That said you should adopt your normal practice and clinical pathways in doing so.
DPLMC advises that you put yourself in a position to make the assessment - you are then in a strong position to discuss the pros & cons of repeat testing in an NHS laboratory with a responsible clinician over seeing result. That clinician does not have to be you - a referral to a specialist may be equally appropriate if it falls out of your individual scope of practice.
