Most people will recover within a week or so, but for others, the flu virus can prove more serious and can even cause death.

There are two ways our physicians can collect a sample for testing. The first is using a special swab to take a sample from your nose or throat. The second is to collect nasal aspirate. This is achieved by injecting saline sedation into your nose before removing the sample using gentle suction.

What Happens If the Result Is Positive?

If the result is negative, you could have some other virus that is causing your symptoms, and we might need to order additional tests before making a diagnosis.

Streptococcal Throat Infections

Strep throat is an infection caused by group A Streptococcus bacteria and which affects the throat and tonsils. These bacteria live in the throat and nose and are easily spread by sneezing and coughing, which creates small droplets containing the virus.

You can catch strep throat if you breathe in these droplets or touch something contaminated by the droplets before touching your mouth or nose. It’s also possible to catch the virus by sharing utensils with someone who is sick or by touching sores on the skin caused by the virus.

Generally, strep throat is a mild infection, but it can be extremely painful. Symptoms include a sore throat that starts very quickly and can cause pain when swallowing. You may feel feverish, and your tonsils could look red and swollen. Your neck lymph nodes may swell, and other symptoms could include a headache, nausea and vomiting, and stomach pain.

Strep throat is more common in children, and especially those aged 5 to 15. Although rare, more serious complications can occur with strep throat and especially if the bacteria spread to other parts of the body. These complications include sinus and ear infections, rheumatic fever, and post-streptococcal glomerulonephritis, which is kidney disease.

Strep Testing in NYC

The only way to determine if you have strep throat is with a rapid strep test. Our physician will gently swab the throat and can test the swab.

The test will quickly identify if group A strep is causing your sore throat and other symptoms, and results are available within minutes. This is far better than the traditional test for strep throat, which is to use a throat culture that takes two or three days to identify the bacteria.

If we do identify strep throat, we can prescribe antibiotics that will reduce the severity of symptoms and shorten the duration of illness. Treating strep throat with antibiotics helps to reduce the possibility of spreading the infection to others.

If you are treated for strep throat, you mustn’t go to work or school until you have taken your antibiotics for at least 24 hours and you no longer have a fever.
