What arrives at your door: a plain outer box with no clinical labels. Inside is the Serenity Swab oral fluid test we ship for this panel, with its printed instruction insert.
What this test screens for
Twelve substances. One simple mouth swab.
This is a 12-panel drug test, so one swab screens for twelve substances at once. Fentanyl and buprenorphine are both on the panel, two things most home tests miss.
How long does fentanyl stay in saliva?
A saliva drug test detects recent use, generally within the last 24 to 48 hours, depending on the substance, the dose and individual metabolism. THC is usually a shorter window in saliva, while benzodiazepines and methadone can run longer. These are ranges, not guarantees, and this is a screening test rather than a confirmatory laboratory test. Detection times in oral fluid vary by substance and are set out in the federal HHS Oral Fluid Mandatory Guidelines, effective January 2020.

How it works
Three steps. Swab to result in about five minutes.
- 01
Swab
Place the absorbent pad between cheek and gum. Hold for about two minutes, until the indicator shows the sample is collected.
- 02
Wait five minutes
Set the device flat on a surface. Watch the saliva travel up the strip until results appear. Read at five minutes.
- 03
Read together
Two lines is a negative. One line is a preliminary non-negative. Read it on your own, or with your provider on a video visit.

From our patients
What people say after their first pack.
The test was easy. The video visit was easy. The whole thing felt private, which is what I needed.
Showed up the next day in a normal box. No one in my house knew what it was. Worked exactly like they said.
I bought the 6-pack for my son. He does it on his calls and we talk after. It has helped a lot.
Six tests for $39.99 versus driving to a lab and paying $80 each time. Easy decision.
Read in two minutes. My provider read it with me. It felt like a real check-in, not a gotcha.
We keep a pack at home and do it together at the kitchen table. Simple enough that it never feels like a confrontation.
Patient stories shown are illustrative examples.

Questions
Everything else.
Is a mouth swab drug test the same as a saliva drug test?
Yes. A mouth swab drug test, a saliva drug test and an oral fluid test are three names for the same thing. You place an absorbent pad between your cheek and gum, it soaks up saliva, and the device reads that sample. The kit insert uses the clinical term, oral fluid.
Does buprenorphine show up on a drug test?
Yes, on a panel that includes it. Buprenorphine, the medication in Suboxone and often just called bup, has its own line on this 12-panel test, marked BUP. If you take it as prescribed, showing non-negative on that line is the expected result and not a problem. Many standard panels do not test for buprenorphine at all, which is why people on it are often surprised either way.
Do I need a prescription for this?
No. You can buy it without one. It is built to be used during a telehealth visit so a provider can read the result with you, but you can also read it on your own.
How does an oral drug test work?
You collect saliva with the swab, set the device flat, and read the lines at home. An oral drug test, also called an oral fluid test, is a screening tool that flags recent use, generally within the last 24 to 48 hours depending on the substance. It is not a confirmatory lab test.
What if I get a non-negative result?
A non-negative on a screening test is a signal, not a final answer. Read it together with your provider on video, or confirm it with a laboratory, and decide what to do next. MedlinePlus, from the National Library of Medicine, describes the follow-up after a false positive as a confirmatory test, a more sensitive test that gives more accurate results.
How long does each substance stay detectable?
Oral fluid testing detects recent use, generally within the last 24 to 48 hours depending on the substance, dose, and individual metabolism. THC in saliva is typically a shorter window. Benzodiazepines and methadone can run longer. Detection windows are ranges, not guarantees.
I take a prescription medication on the panel. Will I show non-negative?
Probably yes. Buprenorphine, methadone, amphetamines, opiates, and benzodiazepines can all show on a screen when taken as prescribed. That is expected. Your provider already knows what you take and reads the result with that context. SAMHSA has background on buprenorphine as a prescribed treatment.
Is this covered by insurance?
Not currently. We sell direct so the price stays low and predictable. The 6-pack works out to $6.67 a test.
How long does shipping take?
Orders placed before the daily cutoff ship the same business day. Most U.S. orders arrive in 2 to 4 days.
What if my package arrives damaged?
Email us a photo within 7 days and we will replace it, free.
Can I return unopened tests?
All sales are final unless your package arrives damaged. We keep prices low by not building return logistics into the cost.
