Hair analysis is now recognized as an effective method for revealing the consumption of drugs and alcohol. Hair preserves a historical record of alcohol and drug intake by embedding biomarkers within the hairs' growing strands. If gathered near the scalp, hair can offer a detection timeframe of up to roughly three months for substances like alcohol and other drugs. Hair collection is straightforward, challenging to tamper with, and convenient for shipping.
A hair sample, 1.5 inches long containing about 200 strands (approximately the thickness of a #2 pencil) nearest to the scalp, will yield 100mg of hair, which is the optimal quantity for both screening and confirmation. For EtG, supplemental, and tests exceeding 10 panels, a 150mg specimen is advised. We suggest measuring the specimen using a jeweler’s scale. In situations where scalp hair cannot be obtained, an equivalent volume of body hair may be utilized. When mentioning head hair, it is in reference only to scalp hair, whereas body hair includes any other hair (facial, axillary, etc.).
Process Overview
The four essential phases in laboratory drug test processing comprise Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the preliminary handling of a sample into the laboratory's system, ensuring the sample is correctly sealed and transported, generating a LAN (Laboratory Accessioning Number), and completing any outstanding data entry absent in an electronic chain of custody system.
Screening provides an initial, swift evaluation for drug misuse. While it efficiently excludes drug use from most samples, any positive outcome in Screening mandates verification for courtroom acceptability. Samples showing a presumptive positive result in Screening necessitate a subsequent confirmation.
Should a sample appear presumptively positive during Screening, additional hair is extracted from the initial collection to prepare for Extraction. Here, drugs are separated from hair at considerably reduced levels compared to other methods (e.g., urine or oral fluid), highlighting the complexity of hair drug screening.
Confirming any positive result from screening is accomplished through GC/MS, GC/MS/MS, or LC/MS/MS. Each presumptive positive sample is washed as required before confirmation. The complete laboratory procedure from Accessioning to Confirmation undergoes review following both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards accreditation.
