Why a walk-in lab
The fastest path to the test you actually want
Most primary-care offices want a referral, an appointment booked weeks out, and insurance billing that ends in surprise charges. We fold all of that into one walk-in visit at our Chantilly lab on Daly Drive, just off Route 50 near the Westfields Corporate Center.
No insurance required
Pay one flat price at check-in. We accept cash, credit, debit, HSA, and FSA cards. Your results never go on your insurance record.
No doctor’s order needed
We include the doctor’s order at no additional charge for almost every test. Walk in, pick what you want screened, and we handle the paperwork.
Walk-in or appointment
Most tests are walk-in friendly. Booking ahead at /book guarantees a specific time slot and a shorter wait on weekends.
In and out under 15 minutes
Typical visit is 10 to 15 minutes from check-in to walking out. Blood draws take about 5 minutes; cheek swabs and drug screens are faster.

FAQ
Walk-in lab questions, answered
Common questions about visiting our Chantilly lab. Don’t see yours? Call us at 571-500-7030.
Do I really need an appointment, or can I just walk in?
You can just walk in. Most tests at our Chantilly lab — blood work, STD panels, drug screens, DNA collections — are walk-in friendly during open hours. Booking ahead at /book locks in a specific time and trims your wait on busy mornings and Saturdays.
How long does a walk-in lab visit usually take?
Most visits take 10 to 15 minutes from check-in to walking out. Blood draws are usually the longest part at about 5 minutes. Drug screens and DNA cheek-swab collections are typically under 5 minutes.
What hours are walk-ins accepted?
Monday through Friday from 9:00 am to 6:00 pm and Saturday from 9:00 am to 1:00 pm. Employer-based drug screens are walk-in only Monday through Friday from 11:00 am to 3:00 pm. We are closed Sunday.
Do I need a doctor’s order to walk in for blood work?
No. Any Lab Test Now of Chantilly includes the doctor’s order at no extra charge for almost every test we offer. Choose your test at check-in and we handle the paperwork — no prior visit to a primary-care doctor required.
Do you accept insurance for walk-in tests?
We do not bill insurance. You see the full price up front, your results never go on your insurance record, and you avoid surprise deductibles. We accept cash, credit, debit, HSA, and FSA cards.
What should I bring to a walk-in lab visit?
Photo ID, any paperwork your employer, court, or doctor has issued, and your payment method. If you are fasting for a lipid or glucose test, plain water is fine but coffee and food are not.
