You can get a drug test at national lab chains like Labcorp and Quest Diagnostics, occupational health clinics like Concentra, many urgent care centers, and some retail pharmacy locations like Walgreens. Most of these facilities accept walk-ins or same-day appointments, and the process typically takes under an hour.
National Lab Chains
Labcorp and Quest Diagnostics are the two largest laboratory networks in the U.S., with thousands of patient service centers combined. Both handle the bulk of employer-ordered drug screens, but they also process tests ordered by individuals. Labcorp offers urine collection, oral fluid (saliva) collection, hair collection, rapid point-of-collection testing, and saliva alcohol screening at locations equipped for each service. Not every location supports every test type, so check availability online before heading in.
These labs follow chain-of-custody protocols, meaning specimens are documented, sealed, and tracked from collection to analysis. That makes results acceptable for employment, legal, and federal purposes. You can schedule an appointment through each company’s website, and many locations also accept walk-ins during business hours. If your employer ordered the test, you’ll typically receive a form or authorization code to bring with you.
Occupational Health and Urgent Care Clinics
Concentra is the largest occupational health chain in the country and specializes in workplace drug testing. They offer 5-panel and 10-panel screens using urine, blood, saliva, or hair follicle samples. Rapid tests return negative results in minutes. Non-negative results and federally regulated tests go to a certified lab, with confirmation typically completed within three to five business days. Concentra also offers “no-THC” panel options in most states for employers who choose not to screen for marijuana.
Many standalone urgent care clinics provide drug testing as well, especially those with an occupational health focus. If you need a test for a new job and your employer hasn’t specified a lab, calling a nearby urgent care center is a practical option. Pricing and test availability vary by location.
Retail Pharmacy Locations
Some Walgreens locations offer employment drug testing through their in-store lab services, alongside routine bloodwork and wellness testing. Availability depends on whether the specific store has lab collection capabilities, so check with your local pharmacy first. CVS MinuteClinic locations have more limited drug testing availability, and services vary significantly by region.
At-Home Drug Test Kits
If you need a quick, informal answer for personal reasons, at-home drug test kits are available at most pharmacies and online retailers for roughly $10 to $50. These kits are fairly sensitive to the presence of drugs in urine, meaning they’ll usually flag a positive if substances are present. However, the FDA cautions that many factors affect accuracy: what the person ate or drank, over-the-counter medications, how the test was stored, and how it was performed. Certain cold medications, for instance, can trigger a positive result for amphetamines even in a lab setting.
A positive result on a home test should be treated as preliminary. The FDA recommends sending the sample to a laboratory for confirmation before drawing any conclusions. Home test results are not accepted for employment, legal, or federal purposes.
What Each Test Method Detects
The type of specimen collected determines how far back the test can look. Urine testing is the most widely used method and detects drug use within roughly one to three days. Saliva testing has the shortest window, picking up very recent use within about one to 36 hours. Hair testing has the longest detection window by far, identifying drug use from roughly a week ago to over 100 days back, since drug compounds get embedded in the hair as it grows. Your employer or the ordering party usually decides which method is used, though if you’re ordering your own test, you can choose based on what timeframe matters to you.
What to Bring
Bring a valid government-issued photo ID, such as a driver’s license, state ID, or passport. Federal guidelines for regulated testing require the collector to verify your identity with a physical photo ID (not a photocopy or fax). If your employer ordered the test, you’ll also need the authorization paperwork, donor pass, or electronic code they provided. Some employers send this directly to the testing facility, but confirm beforehand so you don’t make a wasted trip.
How Long Results Take
Rapid tests, available at many Labcorp locations and Concentra clinics, deliver negative results on the spot. If the rapid screen comes back non-negative, or if the test is sent to a lab from the start, expect results within a few business days. Confirmation testing for positive results adds additional time because a second, more precise analysis is performed. For federally regulated tests, employees have the right to request that a second lab re-test their specimen if the initial result is positive.
Results from employer-ordered tests go to the employer or their designated medical review officer, not directly to you. If you order and pay for a test yourself, results come to you and are protected under federal privacy rules. Substance use disorder treatment records carry especially strong protections under federal law: they generally cannot be shared without your written consent and cannot be used against you in legal proceedings without a court order.
Employer-Ordered vs. Self-Pay Tests
Most people getting drug tested are doing so because an employer required it. In that case, the employer chooses the facility, the panel, and the specimen type. You simply show up where they tell you. Pre-employment tests are the most common, but employers also order random screens, post-accident tests, and reasonable-suspicion tests.
If you’re paying out of pocket for personal reasons, such as monitoring your own use, satisfying a custody agreement, or screening before applying for jobs, you can order a test directly through most lab chains’ websites or through third-party ordering services. Prices generally range from $30 to $65 for a standard urine panel and $100 to $200 or more for hair follicle analysis, though costs vary by provider and region. Self-pay tests use the same collection and analysis methods as employer-ordered ones, so the results carry the same scientific weight.
