Hair testing is widely regarded as an effective method for identifying drug and alcohol consumption. Hair offers a prolonged record of alcohol and other drugs by capturing biomarkers within the fibers of the growing hair shaft. When clipped near the scalp, hair can offer a detection period of up to around three months for alcohol and drugs. Hair is straightforward to collect, somewhat resistant to tampering, and simple to transport.
A 1.5-inch length of roughly 200 hair strands (comparable to the width of a #2 pencil) nearest to the scalp yields 100mg of hair, the optimal sample for both screening and confirmation. For EtG, supplementary analyses, or tests exceeding 10 panels, 150mg of the specimen is advised. It is recommended to weigh the specimen using a jeweler’s scale. If scalp hair is not available, an equivalent amount of body hair may be utilized. The term "head hair" specifically refers to scalp hair only. "Body hair" encompasses all other hair types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result involves four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial phase of processing a sample in a laboratory’s framework. This step includes confirming that the sample was appropriately sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data entry absent from an electronic chain of custody system.
Screening entails an initial rapid assessment for drugs of misuse. Although Screening serves as a cost-efficient method to eliminate drug use in most samples, a positive screen must be verified to be legally admissible. Any samples that show presumptive positivity during Screening require further confirmation.
If a sample tests positive in the Screening phase, additional hair is retrieved from the original specimen for Extraction preparation. In this phase, drugs are extracted from hair at much lower concentrations than with other methods (e.g., urine or oral fluid), which accounts for the complexity of conducting hair drug testing.
Confirmation of any positive screening outcome is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positivity undergo washing before confirmation if necessary. The entire laboratory chain from Accessioning to Confirmation is audited under the CAP (College of American Pathologists) Hair designation and accredited according to ISO / IEC 17025 criteria.
