Quick answer: A rapid flu test uses a quick nasal swab to check for influenza A and B, with results during your visit, often in about 15 minutes. Testing is most useful in the first 48 hours of symptoms, when a positive result can lead to antiviral treatment. Rapid tests can miss some cases, so your provider may still diagnose flu based on symptoms. At PACS Urgent Care, each self-pay rapid test is $45 plus the visit.
Fever, chills and body aches could be flu, COVID-19, RSV or a bad cold. A rapid test takes the guesswork out, so you get the right treatment the same day.
How a rapid flu test works
- A provider gently swabs the inside of your nose
- The sample is tested on site for influenza A and B
- Results are ready during your visit
- Your provider explains the result and your treatment options
We can test for flu and COVID-19 at the same time, and add RSV or strep if your symptoms suggest it. Compare symptoms in cold, flu, COVID or RSV.
When should you get a flu test?
- Within 48 hours of sudden fever, aches and fatigue, when antivirals work best
- If you’re at higher risk: 65+, pregnant, or living with asthma, diabetes or heart disease
- If your child is under 5 or has asthma (see flu in kids)
- If you live with or care for someone high-risk
- If your employer or school needs a diagnosis

How accurate are rapid flu tests?
| Result | What it means |
|---|---|
| Positive | Very likely flu. Your provider can start treatment right away |
| Negative | Flu is less likely, but rapid tests can miss some cases, especially early or late in illness. Your provider may still treat you for flu if your symptoms fit, particularly during peak season |
Testing within the first 3 to 4 days of symptoms, when virus levels are highest, gives the most reliable results.
What happens after a positive test?
- A prescription for an antiviral like oseltamivir (Tamiflu) if appropriate
- Advice on fever, fluids and rest
- A doctor’s note and guidance on when to return to work or school
- Breathing treatments, IV fluids or an X-ray if needed

Yes. We can run both, plus RSV or strep if needed.
Should I get tested if I’ve had symptoms for 5 days?
