Hair analysis is increasingly recognized as a potent method for identifying drug and alcohol consumption. Hair can provide an extended timeline of alcohol and drug use by capturing biomarkers within the fibers of the hair as it grows. When gathered near the scalp, hair can reveal about a 90-day detection window for alcohol and drugs. The collection process for hair is straightforward, its tampering is relatively challenging, and it is convenient for shipping.
A 1.5-inch segment comprising around 200 hair strands (roughly the thickness of a #2 pencil) taken closest to the scalp yields 100mg of hair, which is the optimal sample for evaluation and confirmation. For EtG tests, additional assessments, and/or tests exceeding 10 panels, a specimen amount of 150mg is suggested. The weighing of the sample on a jeweler's scale is advised. If scalp hair cannot be obtained, a comparable quantity of body hair is acceptable. When mentioning head hair, it pertains specifically to scalp hair. Body hair includes all other types of hair (such as facial, axillary, etc.).
Process Overview
The laboratory analysis of a drug test result encompasses four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial step of entering a sample into a laboratory's system. The procedure verifies proper sealing and shipping of the sample, a random LAN (Laboratory Accessioning Number) is assigned, and any necessary additional data entry is completed that was not provided via an electronic chain of custody system.
Screening involves a swift preliminary check for drugs of abuse. While Screening is an economical means to rule out drug use in most cases, a positive result requires confirmation to be suitable for legal proceedings. Any samples that are presumptively positive during Screening demand subsequent confirmation.
Should a sample be presumptively positive during Screening, additional hair is extracted from the original specimen and is prepped for Extraction. At this point, drugs are retrieved from hair at a significantly lower concentration than in other techniques (e.g., urine or oral fluid), which explains why hair analysis is among the most challenging methodologies.
Confirmation of any positive screening result is executed through GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives are cleansed ahead of confirmation as required. The entire laboratory workflow, from Accessioning to Confirmation, is reviewed adhering to both the CAP (College of American Pathologists) Hair designation and the accreditation by ISO/IEC 17025 standards.

Note: Although often termed "hair follicle tests", the actual analysis targets the hair strand and not the follicle beneath the scalp.
