I appreciated how simple the process was. The test was easy to use, and the results were fast and accurate. The Conversation Starter Points made it easier to talk with my daughter about important issues.

Common Questions

What does your hair test screen for?

Tests for 12 substances, including:

AMP, MET, BAR, BZD, THC, COC, PCP, OPI200, OXY, MTD, BUR, FEN, 6-AM  

How private are my results?

Extremely. The only identifier is the 8-digist pin code that you receive with your test. You use this to retrieve your results. No names, birthdays, or similar personal information is used or stored by KNOWN or our lab.

How long does it take to receive my test?

Around 3-5 days. All orders are shipped same-day if possible, or the next business day (excluding Sunday). You will receive a USPS tracking number automatically by email when your order has processed.

How do I collect the hair sample?

Following the simple instructions, you will collect the specified amount of hair as directed, and place it in the labeled plastic bag. Generally it is 1/2" and 90 strands of hair -- about the circumference of a small pencil. The process takes less than 5 minutes.

How do I get my sample to the lab?

Your package will contain a labeled, plastic bag with the supplies for collection. Once collected, you will place the sample back in the bag, and inside the pre-paid return envelope. Be sure to keep the ID card (a branded business card with a blue sticker) with you to read your results.

How do I get my results?

Once the lab has received the results, you can log-in to using the QR code on the branded ID business card and the 8-digit code on the blue sticker. The code is how you will retrieve your results.

How quickly do I get my hair test results?

You'll receive confidential lab results within 5 business days after the lab receives your hair sample. Due to the multiple steps required to prepare and analyze hair, it is not an instant process like urine.

What are your test quality standards?

All of our tests are CLIA-Waived, as well as SAMHSA-Certified. These both represent the highest level of standards applied to at-home drug tests.
