Point Of Care Testing

Point-of-care testing (POCT) is defined by the MHRA (Medicines and Healthcare products Regulatory Agency) as any analytical test performed for a patient by a healthcare professional outside the conventional laboratory setting. Governing bodies, including the MHRA, the NHS Litigation Authority (NHSLA), the International Organisation for Standardisation (ISO), the Royal College of Pathologists (RCPath) and the Clinical Pathology Accreditation (UK) Ltd. (CPA), have all produced guidelines and standards in relation to POCT. To protect patients and staff, use of POCT devices must therefore comply with these regulations and standards.

The MHRA strongly recommends that the laboratory is involved in the management and regulation of POCT to ensure that quality results are produced.
