Recently, hair follicle drug testing has become a more prevalent method for substance screening. Employers, legal systems, and Substance Abuse professionals often favor hair tests over urine tests. Hair tests are the preferred choice for zero-tolerance policies, judicial use, and probation purposes. The main advantage of hair testing is its longer detection window, up to 90 days, coupled with secure collection that makes tampering difficult. For recent drug use, within 5 days, urine tests still provide the best accuracy.

Hair analysis is considered an effective method for identifying drug and alcohol consumption. Hair retains a long-term record of drug and alcohol intake by embedding biomarkers within the fibers of the hair shaft as it grows. When taken near the scalp, hair offers around a 3-month window for detecting alcohol and drug use. It is easy to collect hair, challenging to tamper with, and straightforward to mail.
A sample measuring 1.5 inches, consisting of about 200 hair strands (roughly the thickness of a #2 pencil) near the scalp, will yield 100mg of hair, the preferred amount for testing and verification. For tests such as EtG, add-ons, or tests exceeding 10 panels, it’s suggested to use 150mg of hair. It's advisable to weigh the sample using a jeweler's scale. Should scalp hair be inaccessible, an equivalent portion of body hair can be taken. In discussing head hair, only scalp hair is meant. The term body hair pertains to other types such as facial, axillary, etc.
Process Overview
The laboratory processing of a drug screening result includes four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial integration of a sample into a lab’s system. This step involves checking that the sample was properly sealed and dispatched, giving it a unique LAN (Laboratory Accessioning Number), and filling in any additional information not provided electronically.
Screening is a preliminary rapid test for the presence of drugs of abuse. Though Screening is a cost-effective means to eliminate drug use for most samples, a positive screen must be validated for it to be court-admissible. Samples that test presumptively positive in Screening necessitate subsequent confirmation.
If a sample shows presumptive positivity during Screening, more hair is extracted from the original sample and readied for Extraction. This involves extracting drugs from hair at significantly lower concentrations than those found in other methods (like urine or oral fluid), making hair drug screening the most complex method to execute.
Confirmation of any positive results from the screening is performed via GC/MS, GC/MS/MS, or LC/MS/MS. All samples showing presumptive positivity undergo washing prior to confirmation as deemed necessary. The complete laboratory procedure from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair guidelines and accreditation standards of ISO / IEC 17025.
