Hair analysis is recognized as an effective method for detecting substances such as drugs and alcohol. Hair archives indicators over a prolonged period within its growing fiber strands. When gathered near the scalp, it can offer a detection timeframe of up to roughly three months for drugs and alcohol. The process of gathering hair is straightforward, resisting tampering, and simplifies shipping.
A 1.5-inch collection of approximately 200 strands (comparable to a #2 pencil) near the scalp results in 100mg of hair, the preferred sample size for both screening and confirmation. For EtG, add-ons, or tests exceeding 10 panels, a 150mg quantity is advisable. It's recommended to weigh the hair using a jeweler’s scale. In cases where scalp hair is missing, a similar volume of body hair is acceptable. When we reference head hair, we refer exclusively to scalp hair. Body hair includes all other types (e.g., facial, underarm).
Process Overview
The main stages in the laboratory processing of a drug test involve Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the step where a sample is first integrated into the laboratory's system. This step confirms the sample's integrity, assigns an arbitrary LAN (Laboratory Accessioning Number), and finishes any additional data handling not provided by a digital chain of custody.
Screening entails an initial check for drug abuse substances. Screening is an economical strategy for excluding drug presence across most samples, but a positive screen demands validation for legal reliability. Any samples that suggest positivity during Screening necessitate further confirmation.
Should a sample trigger a presumptive positive during Screening, additional hair from the primary collection is prepared for Extraction. During Extraction, drugs are isolated from hair at much lower concentrations than other methods (e.g., urine, oral fluid), establishing it as one of the most challenging methodologies to execute for drug screening.
Confirmation of positive screening outcomes is achieved through GC/MS, GC/MS/MS, or LC/MS/MS methods. All samples with presumptive positives are cleansed prior to confirmation as conditions require. The entire lab process, from Accessioning through Confirmation, is audited under both the CAP (College of American Pathologists) Hair designation and ISO/IEC 17025 accreditation.
