Reliable laboratory-confirmed diagnosis
Why choose PCR testing?
PCR (polymerase chain reaction) testing is the gold standard for detecting active SARS-CoV-2 infection. A trained clinician gently collects a nasal or throat swab, which is then securely transported to an accredited laboratory. Samples undergo sensitive molecular amplification to detect viral genetic material, providing high accuracy even in early infection. Our process follows strict chain-of-custody and quality protocols to minimise contamination and deliver reliable results. Suitable for symptomatic individuals, contacts of confirmed cases, pre-travel requirements, or workplace screening. Clear guidance is provided before and after testing to ensure comfort and correct interpretation of results.

Simple and quick procedure
What to expect during your test
When you arrive for your PCR swab, our team will check your details and explain the process. The healthcare professional will ask about symptoms and take a nasal or combined nasal and throat swab, which takes only seconds and is usually uncomfortable rather than painful. We provide privacy and support, including step-by-step instructions if you self-swab under supervision. After sampling, the specimen is labelled and logged before transfer to the laboratory. You can expect confirmation of sample receipt and a secure notification of results—typically within 24 to 48 hours depending on laboratory capacity and sample timing.
