Hair testing has evolved into a valuable asset for identifying drug and alcohol consumption. Hair captures a lengthy history of alcohol and drug use by embedding biomarkers within the fibers as the hair strand grows. When collected near the scalp, hair can reveal usage for up to around a 3-month period for alcohol and drugs. It's straightforward to collect, fairly resistant to tampering, and easy to transport.
A hair sample of 1.5 inches, containing roughly 200 strands (about the thickness of a #2 pencil) nearest the scalp, amounts to 100mg of hair, the optimal size for screening and validation. For EtG, additional tests, and/or panels exceeding 10, a 150mg sample is advisable. We suggest weighing the specimen using a jeweler’s scale. If scalp hair isn't available, an equivalent quantity of body hair may be used. "Head hair" refers strictly to scalp hair, whereas "body hair" encompasses all other types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result encompasses four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the preliminary handling of a sample into a lab's system. This process includes confirming the proper sealing and shipping of the sample, allocating a random LAN (Laboratory Accessioning Number), and handling any extra data entry not covered by an electronic chain of custody system.
Screening involves an initial rapid evaluation for drugs of abuse. While Screening efficiently eliminates drug use for most samples, any positive screen must be confirmed for court validity. Samples showing presumptive positivity during Screening mandate a secondary confirmation.
When a sample shows a presumptive positive in Screening, additional hair from the original amount is prepared for Extraction. Drugs are extracted at a very low concentration compared to other techniques (like urine or oral fluid), making hair drug screening exceptionally challenging.
Confirmation of any positive screening result takes place using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives are cleansed prior to confirmation if needed. The full lab process from Accessioning to Confirmation undergoes a review under both the CAP (College of American Pathologists) Hair certification and ISO / IEC 17025 standard accreditation.

Note: Although often termed "hair follicle tests," the test examines the hair strand, not the scalp's hair follicle.
