Hair analysis has emerged as an effective method for identifying drug and alcohol consumption. Hair strands capture indicators within the fibers as they grow, offering an extended chronology of alcohol and drug presence. When snipped near the roots, hair can reveal drug and alcohol exposure over a span of roughly three months. Hair collection is straightforward, relatively hard to tamper with, and convenient for shipping.
A hair sample measuring 1.5 inches, consisting of approximately 200 strands (equivalent to the thickness of a #2 pencil) nearest to the scalp, yields 100mg, which is ideal for both screening and confirmation purposes. For EtG or additional tests exceeding 10 panels, a specimen of 150mg is optimal. Using a jeweler’s scale to weigh the specimen is suggested. In the absence of scalp hair, a similar quantity of body hair may be utilized. The term head hair exclusively denotes scalp hair. Body hair encompasses all other varieties (facial, axillary, etc.).
Process Overview
The laboratory evaluation of drug test results encompasses four key phases: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, a specimen is initially processed into the laboratory database. This step includes confirming the sample’s proper sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and completing any outstanding data entry that an electronic chain of custody system might not cover.
Screening conducts a swift preliminary examination for substances commonly abused. While Screening serves as a cost-efficient method to discount drug use in a majority of cases, a positive result necessitates validation to be legally acceptable. Samples with presumptive positivity during Screening require further verification.
Upon identifying a presumptive positive in the Screening stage, additional hair is extracted from the original sample for the Extraction process. This involves isolating drugs at a significantly lower concentration from hair compared to other methods (such as urine or oral samples), highlighting why hair drug testing remains one of the most challenging techniques.
Verification of any positive results during Screening is achieved via GC/MS, GC/MS/MS, or LC/MS/MS methodologies. Before verification, each presumptive positive sample undergoes necessary washing. The complete laboratory procedure, from Accessioning to Confirmation, undergoes review under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards accreditation.
Advantages of hair drug testing:
Limitations:
Note: Commonly termed "hair follicle tests," these analyses focus on the hair strand itself and not the follicle beneath the skin.
