Hair Testing:
For Historical/Habitual Usage



  • Drugs will stay in the hair shaft until it either grows out or is cut off.

  • Hair testing requires approximately 120-200 head hairs (thickness of a sharpie), or for body hair - the size of a large cotton ball.

  • Hair testing can go back weeks, months, or years depending on the hair, the time frame selected, or the location in which the specimen was collected.

  • Head hair can be broken down, or segmented into different time frames - where body hair or nail testing cannot.

  • Head hair - every 1/2 inch equals approximately 1 month. The standard detection time for a head hair test is approximately 90 days - Sample time frames for standard collections will start approximately 14 prior to the date of collection and test back approximately 90 days. This is due to hair being cut at the scalp, and not pulled from the root.  It takes approximately 10-14 days for any drug use to get into a person's hair or nails. It has to work its way through the body and out into the hair shaft or nail bed.  When hoping to achieve a Negative result, we recommend that you wait at least 2 weeks + 90 days from the date of last drug usage before having a hair sample collected for testing.

  • Body hair is constantly growing and falling out at different rates - within a 6-12 month period. That is why you do not have body hair cut or trimmed like head hair.

  • The standard detection time on body hair is approximately 6-12 months.

  • Samples that test positive in the screening process will move to Confirmation testing via GC/MS &/or LC/MS/MS.  It is important to note that quantitative values cannot be used to determine: time, dosage or frequency of drug use.

  • Confirmation methods used: LC/MS/MS &/or GC/MS.  Liquid chromatography–tandem mass spectrometry (LC–MS-MS) offers specific advantages over gas chromatography–mass spectrometry (GC–MS) such as the ability to identify and measure a broader range of compounds with minimal sample preparation.
