Common Questions, Answered
How accurate is the KNOWN Hair Test?
All tests are processed by a CLIA-certified laboratory, meeting rigorous national standards for accuracy and reliability. Results are over 99% accurate.
What other tests are offered?
In addition to the hair test, we offer an instant 12-panel test, and an instant nicotine test.
Is this a medical diagnosis?
No. The KNOWN Hair Test provides informational results to help guide important family conversations and next steps.
How soon will I get results?
You'll receive confidential lab results in approximately 5 business days after the lab receives your hair sample. Due to the multiple steps required to prepare and analyze hair, the results cannot be expedited.
How private are my results?
Your results are only associated to you via an 8-digit pin. No names, birthdates, or any other personal identifiers are stored.
What quality standards do you have?
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.
