Recognized as a vital instrument in uncovering drug and alcohol consumption, hair analysis provides an extended retrospective by capturing markers within the fibrous structure of growing hair strands. When taken near the scalp, hair offers a retrospective detection window of approximately three months for alcohol and drugs. The hair collection process is straightforward, challenging to tamper with, and simple to transport.
Collecting a 1.5-inch segment comprising about 200 strands (comparable in size to a #2 pencil) nearest to the scalp yields 100mg of hair, which is deemed optimal for analysis and verification. For EtG, additional assessments, and tests beyond ten panels, a 150mg sample is advisable. It's suggested to weigh the specimen using a jeweler’s scale. Should scalp hair be inaccessible, an equivalent quantity of body hair may be obtained. When mentioning head hair, it refers exclusively to scalp hair. Body hair encompasses all other types of hair (such as facial or axillary).
Process Outline
The fundamental stages in laboratory drug test processing encompass Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the preliminary handling of a specimen into a laboratory framework. This involves ensuring the sample was securely sealed and dispatched, assigning a random LAN (Laboratory Accessioning Number), and completing any supplementary data input absent from an electronic chain of custody system.
Screening serves as an initial rapid assay to check for illicit substances. While Screening is an economical method to dismiss drug usage in most samples, a positive screen necessitates confirmation to hold up in legal contexts. Any samples presumptively positive during Screening must undergo a secondary verification.
If a specimen shows presumptive positivity in Screening, more hair is derived from the original sample for Extraction, where drugs are isolated from hair at notably lower concentrations compared to other methods (e.g., urine or oral fluids), underscoring the complexity of performing hair drug analysis.
Detailed Confirmation of any positive screening outcome is executed using techniques like GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo purification before confirmation if necessary. The complete laboratory procedure from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair classification alongside ISO / IEC 17025 accreditation standards.
