The Facts About Strep Culture: How Long Does It Really Take?
Strep culture is a diagnostic test that is used to identify the presence of group A Streptococcus bacteria in patients with symptoms of a strep throat infection. This test involves a swab being taken from the back of the patient’s throat and then sent to a laboratory for testing. While the test is relatively simple and non-invasive, there are some important factors to keep in mind when it comes to how long it takes to get the results.
Factors That Influence How Long It Takes
Several factors can influence how long it takes to get the results of a strep culture test. Some of the most important factors to keep in mind include:
1. Laboratory Processing Time – Most strep culture tests are sent to a microbiology laboratory for processing. The amount of time it takes to get the results back can vary depending on the workload of the lab and how quickly they are able to process the sample.
2. Sample Quality – The quality of the sample collected during the swab can also impact how long it takes to get results. If the sample is not collected properly or is contaminated, it may need to be recollected, which can add time to the process.
3. Type of Test Used – There are different types of tests that can be used to identify group A Streptococcus bacteria. Some tests take longer to process than others, and the specific test used may impact the overall time it takes to get results.
Typical Turnaround Time for Strep Culture Results
In general, it takes between 24 and 48 hours to get the results of a strep culture test back from the laboratory. However, this timeframe can vary depending on the factors listed above. In some cases, it may take longer to get results if additional testing is needed or if the lab is experiencing a high volume of samples.
It’s important to note that rapid strep tests are also available. These tests can provide results in as little as 5 minutes, but they are less accurate than culture-based tests. If you receive a negative rapid test result but still have symptoms of strep throat, your healthcare provider may still order a culture-based test to confirm the diagnosis.
Key Takeaways
Strep culture tests are an important tool for diagnosing strep throat infections. While the test is relatively simple and non-invasive, it can take up to 48 hours to get results back from the lab. However, rapid tests are available if a quicker diagnosis is needed. It’s important to work with your healthcare provider to determine which test is best for your individual situation and to follow their instructions for getting tested and receiving results.
