Hair analysis is now regarded as an effective method for detecting the consumption of alcohol and drugs. Hair strands preserve a comprehensive drug and alcohol usage history by embedding biomarkers within the hair's fibers as it grows. Captured near the scalp, hair samples can offer a detection window of about three months for drugs and alcohol. Collecting hair is straightforward, somewhat resistant to tampering, and simple to send.
An optimal screening and confirmation sample involves a 1.5-inch length from approximately 200 hair strands (comparable to a #2 pencil in size) from the scalp, yielding 100mg of hair. For tests exceeding 10 panels, EtG, or additional tests, a 150mg sample is preferable. We advise using a jeweler's scale to determine specimen weight. In cases where scalp hair is not available, an equivalent quantity of body hair can be collected. Head hair exclusively refers to scalp hair. All other types of hair (facial, axillary, etc.) are classified as body hair.
Process Overview
The laboratory procedure for processing a drug test result comprises four main phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial phase of integrating a sample into a laboratory’s framework. This step ensures the sample is properly sealed and shipped, assigns it a unique LAN (Laboratory Accessioning Number), and includes any supplementary data entry not captured by an electronic chain of custody system.
Screening serves as a preliminary assessment for the presence of drugs. Although Screening is a financially efficient method for excluding drug use in most samples, confirming a positive screen is essential for legal acceptance. Samples that test presumptively positive during Screening necessitate a follow-up confirmation.
When a sample emerges as presumptively positive in Screening, additional hair is retrieved from the primary specimen for Extraction. Drugs are extracted from hair at significantly lower concentrations than other processes (such as urine or oral fluid), rendering hair drug screening the most challenging method.
Confirmation of any screening resultant positives entails GC/MS, GC/MS/MS or LC/MS/MS techniques. Presumptive positive samples undergo washing prior to confirmation as needed. The complete laboratory process, from Accessioning to Confirmation, aligns with the CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditation criteria.
