Recognized as a robust method, hair analysis is effective for identifying drug and alcohol consumption. Trapping biomarkers within the fibers of hair strands as they develop, hair offers a comprehensive long-term history of substance use. When taken from the scalp, it provides a detection timeframe of up to around 90 days for both alcohol and other drugs. The sample collection is straightforward, tampering is challenging, and the sample is easy to transport.
A 1.5-inch portion comprising about 200 strands of hair (approximating the thickness of a #2 pencil) nearest the scalp yields a sample weight of 100mg, which is ideal for analysis. For tests including EtG, additional panels, and tests exceeding 10 panels, a sample size of 150mg is advised. We advise weighing the sample using a jeweler’s scale. If scalp hair isn't available, a similar quantity of body hair can be used. 'Head hair' refers specifically to scalp hair, whereas 'body hair' includes all other hair types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result encompasses four pivotal stages: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the sample undergoes initial processing into the lab's system, ensuring it was properly sealed and dispatched, assigning it a unique LAN (Laboratory Accessioning Number), and completing any necessary additional data entry that isn’t covered by an electronic chain of custody system.
Screening entails an initial rapid assessment of substance abuse. Though a cost-efficient approach to exclude drug use in most samples, a positive result in Screening necessitates further confirmation to be accepted in legal settings. Samples showing presumptive positive results in Screening must undergo secondary confirmation.
Should a sample show a presumptive positive during Screening, additional hair is extracted from the initial sample and prepped for the Extraction phase. Here, drugs are obtained from hair at notably lower concentrations compared to other methods (such as urine or oral fluid), making hair drug analysis the most challenging process to conduct.
Confirmation of any positive screening outcome is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positive results are washed prior to confirmation as necessary. The complete laboratory process, from Accessioning to Confirmation, is assessed under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standard accreditation.
Advantages of hair drug testing:
Limitations:
