Details about MRSA Rapid PCR (Groin)
What is the MRSA Rapid PCR (Groin) test?
The MRSA Rapid PCR (Groin) test uses polymerase chain reaction (PCR) technology to detect the genetic material of methicillin-resistant Staphylococcus aureus (MRSA) from a groin swab. MRSA is a strain of bacteria resistant to commonly used antibiotics and can be carried on the skin without symptoms.
PCR testing is significantly more sensitive and faster than traditional culture methods. It identifies MRSA colonisation even when bacterial levels are low, making it ideal for screening rather than diagnosing active infection.
The groin is a common site of MRSA carriage and is routinely included in screening protocols.
Why do I need an MRSA Rapid PCR (Groin) test?
MRSA colonisation may not cause symptoms but can increase the risk of infection or transmission, particularly in healthcare settings.
You may need this test if you:
-
Are being admitted to hospital or undergoing surgery
-
Require pre-procedure screening
-
Have frequent contact with healthcare environments
-
Live or work in a care facility
-
Have a history of MRSA colonisation
-
Are immunocompromised
-
Need rapid clearance screening
Early detection supports infection control and appropriate precautions.

Your results explained
Negative result
-
MRSA DNA not detected
-
UK standard: Negative
-
No evidence of MRSA colonisation at the time of testing
Positive result

Follow these guidelines for accurate results
Sample Timing
Where possible, attend your blood test between 7am and 12pm. Please wait until any short-term illness or infection has fully resolved before testing. Avoid intense exercise for 24–48 hours beforehand, as this can affect certain markers.
Fasting & Hydration
Fasting is not always required, but some tests may recommend it. If fasting is advised, avoid food for 8–12 hours before your appointment and drink water only. Stay well hydrated, as this helps with sample collection and accuracy.
Medications & Supplements
Continue prescribed medications unless advised otherwise by your clinician. Avoid vitamin, mineral, or biotin supplements for at least 24–48 hours before your test, as these can interfere with results. If you are unsure about any medication or supplement, please let us know before your appointment.
Hormones & Menstrual Cycle
For hormone-related tests, timing within your menstrual cycle may be important. If relevant, follow any specific guidance provided on your test page.
If you have any questions or special circumstances, our team is happy to advise before your appointment.
