Hair testing is recognized as an effective method for detecting drug and alcohol use. It provides a long-term historical record of these substances by embedding biomarkers within the hair's fibers as it grows. When taken near the scalp, hair offers an approximate 3-month detection timeframe for alcohol and other drugs. Hair collection is straightforward, relatively tamper-resistant, and simple to transport.
A 1.5-inch section consisting of about 200 hair strands (roughly the thickness of a #2 pencil) from the scalp can yield 100mg of hair, which is ideal for both screening and confirmation. For EtG, additional tests beyond 10 panels require 150mg of hair. We advise weighing the sample using a jeweler’s scale. If scalp hair is unavailable, an equivalent amount of body hair may be gathered. "Head hair" specifically refers to scalp hair, while "body hair" includes all other types (like facial, axillary, etc.).
Process Overview
The laboratory processing of drug test results involves Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial workflow of a sample in a laboratory system. This step involves ensuring the sample was properly sealed and transported, assigning a LAN (Laboratory Accessioning Number), and completing any missing data entry not supplied by an electronic chain of custody system.
Screening is an initial assessment for the presence of drugs. It serves as a cost-effective measure to negate drug use in most samples, although a positive screening result must be confirmed for legal validation. Samples with a presumptive positive screen require further confirmation.
If the Screening phase indicates a presumptive positive, additional hair from the original sample is prepared for Extraction. This involves extracting drugs from hair at much lower concentrations compared to other methods (such as urine or oral fluid), making hair drug screening a challenging procedure.
Confirmation of positive screenings is performed via GC/MS, GC/MS/MS or LC/MS/MS. All samples with presumed positives are washed before confirmation if necessary. The complete laboratory process from Accessioning to Confirmation adheres to both CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards accreditation.

Limitations:
Note: Commonly known as "hair follicle tests", the actual analysis focuses on the hair strand, not the follicle beneath the scalp.
