What's this test for?

This test is ideal if you're needing to confirm recent marijuana use, whether for personal reasons, employment requirements, or legal purposes. It detects THC metabolites in your urine and reports a ratio that helps distinguish new use from residual traces of past use. Many people use this test before a job screening, for peace of mind, or to track how long THC stays detectable in their system.

What's included in this test?

This test measures marijuana (THC) metabolites in your urine along with a creatinine-based ratio. The ratio matters because it helps tell the difference between a new exposure and metabolites lingering from past use, giving a clearer picture than a simple positive or negative result alone.

What happens after I get my results?

Your results will show up in your account with the metabolite level and ratio explained in plain terms, along with the reference range for a negative result. If your result is positive and you weren't expecting it, consider reviewing recent exposure and retest after a few weeks if you need a clean result for an upcoming screening. You can download a standard lab report straight from your account for any records you need to share. If you test periodically, the trends feature lets you see how your levels change over time.

How can I naturally support faster THC clearance?

Staying well hydrated, being physically active, and eating a balanced diet can help your body process and clear THC metabolites naturally over time, since THC is stored in fat cells and released gradually. Avoiding further marijuana use is the most reliable way to let levels drop. There's no shortcut supplement that reliably speeds up clearance, so consistency with healthy habits is your best approach.

When will I get my results?

Results are typically available within about 7 days of your sample being processed at the lab. You'll get a notification once your report is ready to view in your account. If your timeline is tied to a deadline, it's a good idea to schedule your test with that turnaround time in mind.

Who should consider this test?

This test is a good fit for anyone who needs to verify their THC status, including people preparing for a workplace screening, those monitoring their own use for personal reasons, or individuals who want documentation for legal situations. It's also useful if you've recently stopped using marijuana and want to track how quickly your levels are dropping.

What symptoms indicate I may need this test?

You don't need symptoms to take this test — it's typically ordered for verification purposes rather than to diagnose a health issue. Common reasons include needing proof of THC status for a job, wanting personal confirmation after reducing or stopping use, or fulfilling a legal or program requirement.

What does a positive result mean?

A positive result means THC metabolites were detected above the test's cutoff level, indicating marijuana use within the detection window, which can range from a few days to several weeks depending on frequency of use. The ratio result helps clarify whether this looks like a recent, new exposure or metabolites left over from earlier use. If the result affects something important like employment, understanding your own recent use history is the best way to interpret it.

How often should I retest?

If you're tracking how quickly THC clears your system after stopping use, retesting every one to two weeks can show a helpful trend. If you're testing for a one-time verification purpose, a single test is usually enough unless circumstances change. Frequent heavy use can extend detection time, so more spaced-out retesting may make sense in that case.

What should I do if my results are unexpected?

If your result doesn't match what you expected, first consider any recent exposure to marijuana, including secondhand exposure in some cases. Retesting after a couple of weeks of no use can help confirm whether levels are dropping. If the result carries serious consequences, having the ratio and level details on your downloadable report can provide useful context.
