Hair analysis has become recognized as an effective method for identifying substances of abuse and alcohol consumption. Hair strands retain indicators of alcohol and other drugs within their structure, providing a comprehensive record over an extended period. When cut close to the scalp, hair can present a detection timeframe of up to 90 days for substances. Hair collection is straightforward, hard to tamper with, and simple to transport.
A sample measuring 1.5 inches in length and containing approximately 200 strands near the scalp yields about 100mg, which is optimal for analysis. For EtG, specialized screening, or when the test exceeds 10 panels, a 150mg sample is preferable. A jeweler’s scale is recommended for precise measurement. In the absence of scalp hair, a comparable amount of body hair is acceptable. "Head hair" is strictly scalp hair, while "body hair" encompasses all other types (such as facial or armpit hair).
Process Overview
There are four primary steps in the lab processing of a drug test: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial step, where the sample is integrated into the lab's system. This includes checking that sealing and shipping were correctly performed, assigning a unique LAN, and completing any necessary data not included in an electronic custody record.
Screening is a preliminary check for any indication of drug presence. Though Screening effectively dismisses drug use in most cases, a positive identification requires further verification for legal acceptability. Any initially positive samples from Screening need a second layer of confirmation.
If a positive result appears at Screening, additional hair from the sample is taken for Extraction. This process involves removing substances from the hair at much lower concentrations than other mediums (such as urine or saliva), explaining why hair analysis is a challenging method.
Confirmation of positive results is achieved using GC/MS, GC/MS/MS, or LC/MS/MS. Samples with presumptive positives are cleansed before confirmation as necessary. The whole process, from Accessioning to Confirmation, is scrutinized under both CAP's Hair standards and ISO/IEC 17025 certification.
