Generally, 1.5 to 2 inches of hair from the head or body is needed. Hair tests are capable of analyzing for drugs, alcohol/ETG or providing other tailored hair testing options.
Over recent years, drug testing methods have increasingly included hair follicle testing. Hair drug tests are preferred by employers, courts, and substance abuse professionals over traditional urine tests. Often adopted by zero-tolerance employers, judicial systems, and for individuals on probation, hair follicle tests offer a longer detection period up to 90 days, collected under observation, ensuring it's nearly impossible to tamper with. Nonetheless, for detecting recent drug use within the last 5 days, urine tests remain the top choice.

Hair analysis is recognized as an effective technique for identifying drug and alcohol consumption. Hair captures a long-term record of alcohol and drug usage by embedding biomarkers within the fibers as hair grows. When gathered near the scalp, hair can offer a detection period of up to about 3 months for alcohol and drugs. The collection of hair is straightforward, challenging to tamper with, and simple to transport.
A 1.5-inch segment comprising roughly 200 hair strands (comparable to the width of a #2 pencil) nearest the scalp supplies 100mg of hair, which is the optimal sample for both screening and confirmation. For EtG, additional tests, and tests beyond 10 panels, a specimen of 150mg is advised. It is recommended to measure the specimen using a jeweler’s scale. If scalp hair is not available, an equivalent quantity of body hair can be used. "Head hair" refers exclusively to scalp hair, while "body hair" includes all other types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result involves four main steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial stage of processing a sample into the laboratory’s system. This step includes confirming that the sample was properly sealed and shipped, assigning a unique LAN (Laboratory Accessioning Number), and completing any data entry not handled by an electronic chain of custody system.
Screening provides a preliminary assessment for drugs of abuse. Although Screening is a cost-efficient method to exclude drug use in most samples, any positive screening results must be confirmed for court admissibility. Samples showing a presumptive positive in Screening need a secondary confirmation.
For samples that test presumptively positive during Screening, additional hair is derived from the original sample and prepped for Extraction. This phase involves extracting drugs from hair at significantly lower concentrations than other methods (e.g., urine or oral fluid), making hair drug screening one of the most complex methodologies.
Confirmation of any positive screening results is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives undergo a pre-confirmation wash as required. The entire procedure from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.
