Blood Tests & Laboratory Investigations

At Trinity Medical, we offer a comprehensive range of private blood tests and laboratory investigations, carried out in-clinic by our experienced team and processed by our trusted laboratory partner with fast turnaround times.

Blood tests can be arranged as part of a GP consultation, or booked as a standalone blood draw appointment for patients who have already been advised on which tests they require. Results are typically available within one to two working days, with clear clinical guidance provided alongside your results.

Whether you're looking for a routine health check, investigating specific symptoms, or monitoring an existing condition, we can arrange prompt, accurate testing with clarity and care. Our blood testing and investigation service is available at our Carshalton Beeches clinic, serving patients across Sutton, Wallington, Banstead, and South London.
