Hair screening is now recognized as an efficient instrument for identifying drug and alcohol consumption. Hair strands can capture long-term evidence of substance use by encasing biomarkers within the developing hair fibers. When hair is cropped close to the scalp, it can offer a detection window of up to roughly three months for alcohol and various drugs. This method of collection is straightforward, relatively tamper-resistant, and effortless to transport.
An adequate sample comprises a 1.5-inch segment from about 200 hair strands (similar to the width of a #2 pencil) closest to the scalp, which yields 100mg, the preferred amount for analysis and verification. For EtG, additional analyses, and more than 10-panel assessments, 150mg is advised. Using a jeweler's scale is suggested for accuracy. If scalp hair cannot be obtained, body hair of equivalent quantity may be used. Head hair specifically refers to scalp hair, whereas body hair includes all other forms (facial, axillary, etc.).
Process Overview
The laboratory procedure for analyzing a drug test outcome comprises four fundamental stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the preliminary handling of a sample into a lab's database. This step includes checking proper sealing and shipment of the sample, assigning an arbitrary LAN (Laboratory Accessioning Number), and filling in any missing details not captured by an electronic chain of custody.
Screening facilitates an initial swift assessment for substance misuse. While it is an economical method to rule out drug use for most samples, a positive result requires confirmation to be legally valid. Samples with presumptive positives in Screening necessitate further verification.
If a specimen appears positive during Screening, more hair is extracted from the primary sample for the Extraction phase. Here, substances are isolated from hair at a significantly lower concentration than in other techniques (e.g., urine or saliva), which makes hair drug screening particularly complex.
Verification of any positive throughput in Screening is executed using GC/MS, GC/MS/MS, or LC/MS/MS technology. All preliminary positive samples undergo a cleansing process as needed before confirmation. The comprehensive lab workflow from Accessioning to Confirmation is scrutinized under both CAP (College of American Pathologists) Hair classification and compliance with ISO / IEC 17025 standards.
