FAQ
Questions we hear most
Still unsure? Call 571-500-7030 and we’ll walk you through your options.
Do I need a doctor’s order to get a lab test?
No. Any Lab Test Now of Chantilly provides the doctor’s order at no extra charge for almost every test we offer. Walk in, choose your test, and we take care of the paperwork. You can also book an appointment ahead of time for the quickest visit.
Do you accept insurance?
We do not accept insurance — and that’s by design. You see the full price up front, your results never go on your insurance record, and you avoid surprise deductibles or balance billing. We accept cash, debit, credit, and HSA / FSA cards.
How fast will I get my lab results?
Most blood-work, STD, and drug-test results are returned in 24 to 72 hours through our secure online patient portal. Some rapid tests — including our COVID-19 RT-PCR swab — return same-day results in 1–2 hours.
Can I walk in or do I need an appointment?
Either way works. Walk-ins are welcome during open hours, and employer-based drug screens are walk-in only (M–F, 11 am–3 pm). For everything else, booking a time slot gets you in and out fastest. Call 571-500-7030 or reserve online.
How private is my testing?
Completely. We are HIPAA-compliant, your results are not sent to your insurance carrier, and our staff is trained to handle every visit with discretion. Results are delivered through a secure password-protected online portal that only you can access.
