Hair examination is increasingly recognized as an effective means for identifying drug and alcohol consumption. Hair retains a long-term record of alcohol and drugs by capturing biomarkers within the fibers of the hair as it grows. When taken near the scalp, hair offers a detection window for alcohol and drugs extending up to roughly three months. Hair is straightforward to gather, somewhat challenging to tamper with, and easy to transport.
A sample of hair measuring 1.5 inches and composed of about 200 strands (roughly the size of a #2 pencil) nearest to the scalp will produce 100mg of hair, ideal for screening and confirmation. For EtG, additional tests, or panels exceeding 10, a specimen of 150mg is advisable. We suggest using a jeweler’s scale to determine the specimen weight. If scalp hair is unavailable, a similar quantity of body hair can be taken. By "head hair," we specifically mean scalp hair, whereas "body hair" encompasses all other types of hair (facial, axillary, etc.).
Process Overview
The principal steps in processing a drug test result in the laboratory include Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the inaugural processing of a specimen into the lab’s system. This process verifies that the sample was properly sealed and transported, assigns a random LAN (Laboratory Accessioning Number), and completes any extra data processing not provided by an electronic chain of custody system.
Screening serves as an initial swift examination for illicit drug use. While Screening is a cost-efficient method to rule out drug consumption in most samples, a positive screen must be confirmed for court admissibility. Any samples preliminarily positive in Screening necessitate a secondary confirmation.
If a sample shows preliminary positivity during Screening, additional hair is extracted from the original specimen for further preparation in Extraction. In this phase, drugs are extracted from hair at considerably lower concentrations than other techniques (such as urine or oral fluid), highlighting the complexity of hair drug screenings.
Confirmation of any positive screening finding is achieved through GC/MS, GC/MS/MS, or LC/MS/MS. All samples preliminarily positive are washed before confirmation as necessary. The comprehensive laboratory process, from Accessioning to Confirmation, undergoes review under CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Note: Although termed "hair follicle tests," the analysis targets the hair strand itself rather than the follicle under the scalp.
