Hair analysis has emerged as an effective mechanism for identifying drug and alcohol consumption. Hair offers a comprehensive timeline of alcohol and drugs by capturing biomarkers within the fibers of the developing hair shaft. When collected close to the scalp, hair samples can reflect about a 3-month detection period for alcohol and other substances. It is straightforward to collect, somewhat hard to tamper with, and convenient for transportation.
A sample measuring 1.5 inches with around 200 hairs (comparable to the width of a #2 pencil) closest to the scalp provides 100mg of hair, which is the ideal quantity for examination and confirmation. For EtG, extra panels, and/or tests over 10 panels, 150mg of the sample is advisable. It is recommended to weigh the sample using a jeweler’s scale. If scalp hair is not present, an equivalent volume of body hair can be used. When mentioning head hair, it specifically refers to scalp hair. Body hair includes all other hair types (facial, axillary, etc.).
Process Summary
The four essential stages in the laboratory assessment of a drug test result are Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes the initial handling of a sample into a lab’s framework. This encompasses verifying proper sealing and shipping of the sample, allocating a random LAN (Laboratory Accessioning Number), and finalizing any extra data entry absent from an electronic chain of custody system.
Screening provides an initial swift check for drug misuse. While Screening offers a cost-efficient approach to negate drug usage in most samples, a positive screening result must be confirmed for legal admissibility. Any samples that test positive in Screening require a subsequent confirmation.
If a sample is positive in the Screening phase, additional hair is extracted from the original specimen and set for Extraction. During this phase, drugs are extracted from hair at much lower concentrations compared to other methods (e.g., urine or oral fluid), rendering hair drug screening as the most challenging method to execute.
Confirmation of any positive screening result takes place using GC/MS, GC/MS/MS, or LC/MS/MS. All positive samples are cleansed prior to confirmation as necessary. The complete laboratory process from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair classification and in accordance with ISO / IEC 17025 standards.
