If you’re feeling sick with flu-like symptoms, you may need a flu test to find out if you have the virus. So, Basically The time it takes to get your test results depends on the type of test you take. Some tests provide results in as little as 10 minutes, while others may take a few hours or even days if sent to a lab.
In this article, we’ll explain how long different flu tests take, where you can get tested, and what to expect from the results.
How Long Does a Flu Test Take? — Types, Purpose, Procedure & Results!
Fundamentally, Flu tests are quick and simple procedures. The actual process of collecting a sample usually from your nose or throat takes less than a minute. However, the waiting time for results varies based on the type of flu test you take.
Check Out below the different flu tests and how long they take:
1. Rapid Influenza Diagnostic Tests (RIDTs)
- Time to collect the sample: Less than 1 minute
- Time to get results: 10 to 30 minutes
- Accuracy: 50% to 70%
Hence, RIDTs are the most commonly used flu tests. They detect flu antigens (proteins from the virus) in your body. While they provide fast results, they aren’t always the most accurate, and false negatives can occur.
2. Rapid Molecular Assays
- Time to collect the sample: Less than 1 minute
- Time to get results: 15 to 30 minutes
- Accuracy: More accurate than RIDTs
Another type of rapid test is the Rapid Molecular Assay these tests look for genetic material of the flu virus, making them more reliable than rapid antigen tests. They are also point-of-care tests, meaning they can be done at a clinic without sending the sample to a lab.
3. Reverse Transcription-Polymerase Chain Reaction (RT-PCR) Tests
- Time to collect the sample: Less than 1 minute
- Time to get results: 45 minutes to 3 hours (sometimes longer)
- Accuracy: 90% or higher
For even more accurate results, doctors may recommend the Reverse Transcription Polymerase Chain Reaction (RT-PCR) Test. PCR tests detect flu viruses with high accuracy. While some clinics have machines that can process results in under an hour, many PCR tests are sent to a laboratory, which can take a few hours to a couple of days.
4. Immunofluorescence Tests
- Time to collect the sample: Less than 1 minute
- Time to get results: 2 to 4 hours
- Accuracy: Higher than rapid antigen tests but not as high as PCR tests
Less commonly, an Immunofluorescence Test may be used these tests use fluorescent dyes and microscopes to detect flu viruses. They are more commonly done in hospital labs rather than in urgent care or clinics.
Factors That Affect How Long Flu Test Results Take!
Several factors can influence how quickly you get your flu test results. The type of test is the most significant factor, but the location where you’re tested also plays a role. For example, urgent care centers and pharmacies often rely on rapid tests to provide results while you wait, making them convenient options if you need to know quickly.
On the other hand, if you visit a hospital or your Primary care doctor, they might use more comprehensive tests that require lab processing, which can extend the wait time. The time of year can also affect turnaround times.
During flu season, when clinics and labs are handling a higher volume of tests, it may take longer to process samples, especially if they need to be sent to an external lab.
Additionally, if you’re using an at-home flu test kit that requires mailing your sample to a lab, you’ll need to factor in shipping time, which could add an extra day or two before you receive your results.
How Accurate Are Flu Tests?
While speed is important, accuracy is equally critical when it comes to flu testing. Rapid tests like RIDTs are convenient, but their accuracy can range from 50% to 70%, meaning there’s a higher chance of false negatives, particularly in adults. This is why doctors often consider your symptoms and exposure history along with test results when making a diagnosis.
Molecular tests, such as rapid molecular assays and RT-PCR tests, offer significantly higher accuracy, often between 90% and 100%. These tests are better at detecting the flu virus even when it’s present in smaller amounts, reducing the likelihood of false negatives. The most accurate results are typically obtained within the first 48 to 72 hours after symptoms start, which is when the virus is most active in your body.
Where Can You Get a Flu Test?
Flu tests are widely available at various healthcare facilities, including doctor’s offices, urgent care clinics, hospitals, and even some pharmacies like CVS and Walgreens. Many pharmacies now offer rapid flu testing services without an appointment, making it convenient to get tested quickly.
At-home flu tests have also become more popular. These kits allow you to collect a sample yourself and either get immediate results (if it’s a rapid test) or send the sample to a lab for analysis. While at-home tests can be convenient, especially if you’re trying to avoid public places while sick, it’s essential to follow the instructions carefully to ensure an accurate result.
How Much Does a Flu Test Cost?
Somehow, The cost of a flu test can vary depending on the type of test, where you get tested, and whether you have health insurance. Rapid tests are generally less expensive, with costs ranging from $5 to $20, especially if you get tested at a pharmacy. More advanced tests like RT-PCR can be more costly, with prices ranging from $100 to $200 or more if processed in a lab.
Many insurance plans cover the cost of flu testing, especially if it’s medically necessary. If you’re uninsured, some clinics and pharmacies offer low-cost or free testing during flu season, particularly through public health programs. It’s always a good idea to check with the testing site in advance to understand any costs involved.
