What is the MRSA Rapid PCR (one swab per site) test?

The MRSA Rapid PCR (one swab per site) test uses polymerase chain reaction (PCR) technology to detect the DNA of methicillin-resistant Staphylococcus aureus (MRSA) from a single, specified body site. Common screening sites include the nose, throat, groin, wounds, or skin lesions.

PCR testing is highly sensitive and can identify MRSA even when bacterial levels are very low. Each swab tests one anatomical site only, allowing targeted screening based on clinical or institutional requirements.

This test is designed to detect MRSA colonisation, not to diagnose active infection.

Why do I need an MRSA Rapid PCR test?

MRSA carriage often causes no symptoms but increases the risk of transmission and infection, particularly in healthcare environments.

You may need this test if you:

• Require pre-admission or pre-surgical screening

• Are undergoing an invasive procedure

• Work in healthcare or residential care

• Have had previous MRSA colonisation

• Are immunocompromised

• Need clearance screening

• Have been advised to screen a specific site only

Targeted single-site testing allows focused and efficient screening.

Benefits of the test

1. Rapid detection using PCR technology
   Faster than traditional culture methods.

2. Highly sensitive and specific
   Detects low-level MRSA colonisation.

3. Targeted single-site screening
   Tests only the required anatomical site.

4. Ideal for pre-procedure screening
   Commonly accepted in clinical pathways.

5. Non-invasive sampling
   Simple swab collection.

6. Suitable for asymptomatic individuals
   No signs of infection required.

7. Supports infection control measures
   Helps reduce MRSA spread.

8. Flexible testing approach
   Multiple sites can be tested if required, using separate swabs.

Step-by-step: How we offer testing

Clinic-based testing (UK-wide)

• Choose your nearest UK clinic

• Single swab taken from the required site

• Sample sent to the laboratory for PCR analysis

• Results issued once testing is complete

Home or hotel visit (+£60, UK-wide)

• Swab collected at home or hotel where appropriate

• Sample securely transported to the laboratory

Your results explained

Negative result

• MRSA DNA not detected

• UK standard: Negative

• No evidence of MRSA colonisation at the tested site

Positive result

• MRSA DNA detected

• UK standard: Positive

• Indicates MRSA colonisation at the sampled site

Colonisation does not mean active infection but may require infection control precautions depending on context.
