MRGN - Rectal Swab

Three reasons the Multidrug-resistant Gram-negative (MRGN) Rectal Swab test is right for you

• This test screens for multidrug-resistant Gram-negative bacteria in the gastrointestinal tract, including carbapenemase-producing organisms
• It helps prevent the spread of highly resistant bacteria in healthcare or community settings
• Results assist clinicians in implementing appropriate infection control measures and guiding treatment if needed

What is the MRGN Rectal Swab test?

The MRGN Rectal Swab test identifies colonisation by multidrug-resistant Gram-negative bacteria (MRGN), including carbapenemase-producing organisms (CPO). These bacteria are resistant to multiple antibiotics and can cause serious infections, particularly in hospitalised or immunocompromised patients. Screening is performed using a rectal swab, which is analysed in a laboratory for the presence of resistant bacteria.

This test is often recommended for:

• Individuals admitted to or being discharged from hospitals or long-term care facilities
• Patients with a history of recent antibiotic use or recurrent infections
• People exposed to environments with known outbreaks of multidrug-resistant bacteria
• Monitoring infection control in high-risk populations

What are the risks of MRGN colonisation?

Colonisation with MRGN bacteria may not cause immediate symptoms, but it can lead to severe infections if bacteria spread or the immune system is weakened. Potential risks include:

• Urinary tract infections, bloodstream infections, or pneumonia
• Limited treatment options due to antibiotic resistance
• Increased risk of complications in hospitalised or immunocompromised patients
• Potential for transmission to family members or other contacts

How does the MRGN Rectal Swab test work?

A trained healthcare professional collects a rectal swab sample using a sterile swab. The sample is sent to an accredited laboratory where it is cultured and analysed for the presence of multidrug-resistant Gram-negative bacteria, including carbapenemase-producing organisms.

What can I expect at my appointment?

Your appointment involves a simple rectal swab performed by a trained professional. The procedure is quick, safe, and usually takes only a few minutes. You may feel slight discomfort, but the process is minimally invasive.

The sample is analysed in the laboratory, and results are typically available within a few days. Your report will indicate whether multidrug-resistant bacteria were detected, helping guide any necessary infection control measures or treatment.

Are there any risks with this test?

This is a routine screening test and is very safe. Most people experience only mild discomfort during the swab. Rarely, minor irritation or a temporary sensation of pressure may occur. Serious complications are extremely uncommon.
