What does a positive MRSA nasal swab mean?
If the test is positive, it means that at the moment your nose was swabbed, MRSA was present. You are considered “colonized” with MRSA, or a carrier. If the test is negative, it means that you are not “colonized” with MRSA.
How is MRSA in the throat treated?
MRSA carriers have routinely been treated since 2009. Our current guideline recommends adding antibiotics to the standard regimen, clindamycin being our first line choice, on the second or third eradication attempt if the patient is a throat carrier and the isolate is clindamycin susceptible.
What swab is used for influenza?
A nasopharyngeal (NP) swab is the optimal upper respiratory tract specimen collection method for influenza testing. However, such specimens cannot be collected from infants and many older patients may not allow an NP specimen to be collected.
What is MRSA swab test for?
A methicillin-resistant Staphylococcus aureus (MRSA) screen tests solely for the presence of MRSA and no other microbes. It is primarily used to identify the presence of MRSA in a colonized person so they can be treated to eliminate MRSA and prevent its spread to others.
What does a positive MRSA culture mean?
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.
What do you do if you test positive for MRSA?
What to Do if You Test Positive for MRSA
- Remind your doctors, nurses and other health care providers to clean their hands before touching you or items in the room.
- Ask visitors to clean their hands when they enter and leave your room.
What are the symptoms of MRSA in the throat?

- pain with swallowing.
- headache.
- body aches.
- red throat.
- enlarged tonsils with white spots.
- tender, swollen glands (lymph nodes) in the front of your neck.

Can MRSA affect your throat?
Among 17% of patients, the throat was the only site where MRSA was detected. In patients in close contact with a known MRSA patient, 53% were throat carriers of MRSA. Among 33%, the throat was the only sample site with MRSA.
How is influenza diagnosed?
To diagnose the flu, health care providers will first do a medical history and ask about your symptoms. There are several tests for the flu. For the tests, your provider will swipe the inside of your nose or the back of your throat with a swab. Then the swab will be tested for the flu virus.
Can a person with MRSA pneumonia swallow sputum?
Thus, patients with MRSA pneumonia would be expected to have MRSA colonization of the throat. Some patients with MRSA PNA may be too weak to expectorate sputum, swallowing it instead. Throat culture might be especially sensitive in these patients, who are continually trafficking MRSA through their throat.
Which is more sensitive MRSA PCR or nares?
Several studies involving >4,000 patients show that the combination of nares plus throat culture is 5-20% more sensitive than nares culture alone for detecting MRSA colonization (8). This provides the basis for testing the throat among patients with a negative nares PCR.
How is MRSA colonized in the upper airway?
MRSA commonly colonizes the upper airway of asymptomatic people. Imagine that a person colonized with MRSA develops pneumonia with an organism that is difficult to detect (e.g. mycoplasma or viral pneumonia). The patient’s sputum may be contaminated with MRSA from their upper airway, leading to an incorrect diagnosis of “MRSA pneumonia.”
Why do you need throat culture for pneumonia?
Throat culture becomes relevant among patients who are unable to produce an adequate-quality sputum sample. This is theoretically attractive for two reasons: MRSA usually causes pneumonia by first causing colonization of the oropharynx, then being aspirated into the lungs.
