Hair testing is now widely recognized as a robust method for detecting drug and alcohol consumption. By capturing biomarkers in the strands of growing hair, it offers a long-term record of alcohol and drug use. Collected near the scalp, hair can reveal usage over a period of up to three months for both alcohol and drugs. Hair collection is straightforward, hard to tamper with, and simple to transport.
A hair sample taken from about 200 strands, measuring 1.5 inches and comparable to a #2 pencil, provides 100mg of hair, which is the best sample size for screening and confirmation. For tests involving EtG, add-ons, or those exceeding 10 panels, 150mg of hair is advised. We suggest using a jeweler's scale to measure the sample. If scalp hair is unavailable, a equivalent weight of body hair may be used. Head hair refers exclusively to scalp hair, while body hair includes all other types (such as facial and axillary hair).
Process Overview
The laboratory processing of drug test results involves four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning means the initial submission of a sample into a laboratory's system. This step includes verifying that the sample was sealed and transported correctly, assigning a random LAN (Laboratory Accessioning Number), and completing additional data entries not covered by an electronic chain of custody system.
Screening is an initial rapid check for drugs. While it is a cost-efficient way to rule out drug use for most samples, a positive screen must be confirmed for court admissibility. Any sample that tests presumptively positive during Screening requires secondary confirmation.
If a sample is presumptively positive in the Screening phase, additional hair is taken from the original specimen and readied for Extraction. During this phase, drugs are extracted from the hair at concentrations much lower than in other methods (e.g., urine or oral fluid), making hair drug screening more complicated to perform.
Confirmation of any positive screening result is carried out through GC/MS, GC/MS/MS, or LC/MS/MS. All samples that test presumptively positive are washed before confirmation as necessary. The entire laboratory process, from Accessioning to Confirmation, is evaluated under the CAP (College of American Pathologists) Hair accreditation as well as ISO / IEC 17025 standards.
