The perception of hair testing has evolved into an effective means for identifying the use of drugs and alcohol. Hair captures a prolonged timeline of alcohol and drug presence by embedding biomarkers within its growing strands. When closely trimmed to the scalp, hair samples can cover nearly a three-month detection timeframe for substances. Collection of hair is straightforward, relatively challenging to tamper with, and convenient to transport.
A sample length of 1.5 inches containing roughly 200 hair strands (comparable to the thickness of a #2 pencil) taken from the scalp yields 100mg, considered the optimal amount for both screening and confirmation. For EtG, supplemental tests, or assessments exceeding 10 panels, 150mg of the specimen is advised. Using a jeweler’s scale for weighing the sample is suggested. If scalp hair is unavailable, an equivalent quantity of body hair may be used. References to head hair specifically denote scalp hair. Body hair encompasses all other hair varieties (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result encompasses four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the sample's initial integration into the laboratory’s system. This involves confirming the appropriate sealing and shipping of the sample, assigning a unique LAN (Laboratory Accessioning Number), and completing any outstanding data entry not handled by an electronic chain of custody system.
Screening provides a preliminary check for drug presence. Although Screening is an economical method to dismiss drug usage for most samples, a positive screening must be verified for legal admissibility. Samples with presumptive positive results from Screening require further confirmation.
Should a sample yield a presumptively positive result during Screening, additional hair is extracted from the original sample for the Extraction phase. Here, drugs are isolated from hair at significantly lower concentrations compared to other approaches (e.g., urine or oral fluid), highlighting the complexity of hair drug screening.
Any positive results from Screening undergo Confirmation through methods like GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive specimens are cleansed before confirmation as necessary. The complete laboratory process from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair classification and meets the ISO / IEC 17025 standards.
