What lab tests are done for MRSA?
Doctors diagnose MRSA by checking a tissue sample or nasal secretions for signs of drug-resistant bacteria. The sample is sent to a lab where it’s placed in a dish of nutrients that encourage bacterial growth.
How do you test for MRSA?
A nurse will run a cotton bud (swab) over your skin so it can be checked for MRSA. Swabs may be taken from several places, such as your nose, throat, armpits, groin or any damaged skin. This is painless and only takes a few seconds. The results will be available within a few days.
Is there a blood test for MRSA infection?
Blood Test A test can also be used to determine whether you’re infected with methicillin-resistant Staphylococcus aureus (MRSA), a type of staph that’s resistant to common antibiotics.
Does labcorp do MRSA swabs?
MRSA screening tests include: Bacterial culture – a nasal swab is collected from the nares (nostrils) of an asymptomatic person and cultured (put onto a special nutrient medium, incubated, and then examined for the growth of characteristic MRSA colonies).
What happens if I test positive for MRSA?
If your results are positive, it means you have a MRSA infection. Treatment will depend on how serious the infection is. For mild skin infections, your provider may clean, drain, and cover the wound. You may also get an antibiotic to put on the wound or take by mouth.
Why do they swab for MRSA?
Patients with MRSA colonization are potential reservoirs for transmission and are themselves at higher risk of acquiring MRSA-associated infections. Nasal-swab screening is currently used at the study centre to identify MRSA carriers and to direct appropriate isolation of colonized patients.
What does it mean if you test positive for MRSA?
If your MRSA test is positive, you are considered “colonized” with MRSA. Being colonized simply means that at the moment your nose was swabbed, MRSA was present. If the test is negative, it means you aren’t colonized with MRSA.
Are you a MRSA carrier for life?
Even if active infections go away, you can still have MRSA bacteria on your skin and in your nose. This means you are now a carrier of MRSA. You may not get sick or have any more skin infections, but you can spread MRSA to others.
Is a person with MRSA always contagious?
As long as there are viable MRSA bacteria in or on an individual who is colonized with these bacteria or infected with the organisms, MRSA is contagious. Consequently, a person colonized with MRSA (one who has the organism normally present in or on the body) may be contagious for an indefinite period of time.
