What this test screens for
Understanding the COVID-19 Rapid Antigen
The COVID-19 Rapid Antigen Test detects COVID-19 antigens — viral proteins — in a nasal swab sample. Results are available in 15 to 20 minutes at our Ashburn lab, making this the right option when you need a same-visit result for travel documentation, employer requirements, or symptom-onset testing.
At our Ashburn lab, the rapid antigen test is $69 with no doctor referral required. Walk in during open hours. Rapid antigen tests are most sensitive when performed within the first 5 to 7 days of symptom onset, when viral load is typically highest. If you are asymptomatic but need a test for travel, check the destination’s accepted test type before coming in — some require PCR.
Antigen tests are excellent for detecting active, high-viral-load infection. Sensitivity is generally lower than PCR, particularly in asymptomatic individuals or very early in infection. A negative rapid antigen result does not fully rule out COVID-19 in someone with strong symptoms — a follow-up PCR provides higher sensitivity. We provide a signed, dated result card and a digital copy through your patient portal.
Why people get this test
- Symptom-onset testing when you want a fast result
- Travel documentation requirements that accept rapid antigen results
- Employer return-to-work requirements
- Pre-event or pre-visit testing to reduce transmission risk to vulnerable individuals
- Testing after a known exposure when symptoms have started
What to expect
From check-in to results — what your visit looks like
Most visits take under 15 minutes. Here’s the full arc, start to finish.
How to prepare
No fasting required. Do not eat, drink, smoke, or use nasal spray for at least 30 minutes before the swab — residue in the nasal passage can affect result accuracy.
During your visit
A brief nasal swab collected by a trained staff member in a private collection room. The swab is quick — most clients find it mild to moderately uncomfortable for a few seconds. Results are ready in 15 to 20 minutes. We provide a signed result card on-site and a digital copy through your patient portal.
Getting your results
Results in 15 to 20 minutes. A positive result indicates COVID-19 antigens were detected and is highly specific — false positives are uncommon. A negative result means antigens were not detected at the time of the test, which does not completely rule out infection — especially in asymptomatic individuals or early in infection. We provide a dated, signed result card suitable for travel, employer, or personal documentation.
Confidential

FAQ
COVID-19 Rapid Antigen Test — what people ask
Specific questions about the covid-19 rapid antigen test. For anything not covered, call 571-500-7030.
Is a rapid antigen test accepted for travel?
It depends on the destination. Many destinations accept rapid antigen tests; others require PCR. Check the specific requirements for your destination before your visit — requirements change frequently. We can advise which test type is appropriate when you call ahead.
How accurate is a rapid antigen test compared to PCR?
PCR is the reference standard and has higher sensitivity — it can detect COVID-19 at lower viral loads and earlier in infection. Rapid antigen tests are highly accurate when viral load is high (typically during the symptomatic phase). For asymptomatic screening or very early infection, PCR is more reliable. If symptoms are strong and a rapid antigen test is negative, a follow-up PCR provides higher confidence.
If I test positive, do I need to do anything specific?
Follow current CDC guidance for COVID-19 isolation, which is updated periodically. Inform close contacts. If you are at high risk for severe disease, contact a primary-care provider promptly — antiviral treatment options are most effective when started early after symptom onset.
