Can You Get a False Negative Strep Test ?

Strep throat is a bacterial infection that affects the throat and tonsils. In order to diagnose this condition, rapid strep tests are used to detect the presence of Streptococcus bacteria. While these tests are usually accurate, there are certain circumstances in which a false negative result can occur. This article will discuss what causes false negative strep tests, as well as how to prevent them from happening.

What Causes False Negative Strep Tests ?

A false negative strep test occurs when someone has the bacteria that cause strep throat but the rapid test does not detect it. There are several possible reasons for this :

  • Viruses : Viruses can sometimes interfere with the accuracy of the test results. This is because viruses have similar symptoms as strep throat but do not contain the same bacteria.
  • Incorrect Sample Collection : The sample must be collected correctly in order to get an accurate result. If the sample is taken too soon after exposure or if it is not handled properly, the test may not be able to detect the bacteria.
  • Improper Handling of Results : If the results are not interpreted correctly or if they are mishandled, then the results may not be accurate.
  • False Positives : False positives can also occur if the test detects something other than strep throat, such as another type of bacteria or virus.

How Can False Negative Strep Tests Be Prevented ?

There are several steps that can be taken to reduce the chance of getting a false negative strep test result :

  1. Ensure that the sample is collected correctly. This includes following the instructions on the package insert and ensuring that the sample is not exposed to any contaminants.
  2. Check that the test results are interpreted correctly. Make sure that the health care provider knows how to read the results and understands the implications of a positive or negative result.
  3. Discuss any potential risk factors with your doctor. If you have any medical conditions or take any medications that could affect the accuracy of the test, make sure to let your doctor know.
  4. Consider alternative testing methods. Some alternative testing methods, such as culture testing, can provide more accurate results than rapid strep tests.
  5. Make sure to follow up with your doctor. Even if the initial test comes back negative, it is important to follow up with your doctor to ensure that the condition is indeed not present.

False negative strep tests can occur due to a variety of factors, including viruses and incorrect sample collection. To reduce the chance of getting a false negative result, it is important to ensure that the sample is collected correctly, the results are interpreted properly, and alternative testing methods are considered. It is also important to follow up with your doctor to confirm the diagnosis.
