Hair screening is recognized as a potent means for uncovering drug and alcohol consumption. The hair offers an extended record of substance use by embedding biomarkers within the strands. When sampled near the scalp, it can reveal a substance use profile spanning up to three months. The collection process for hair is straightforward, challenging to tamper with, and easy to transport.
Collecting a section measuring 1.5 inches totaling around 200 hairs (approximately the diameter of a #2 pencil) near the scalp yields 100mg of hair—the preferred volume for analysis and confirmation. For EtG, additional tests, and tests above 10 panels, 150mg is suggested. It's advisable to measure the sample using a jeweler’s scale. If head hair is inaccessible, body hair of equal mass may be used. When discussing head hair, it refers exclusively to scalp hair. Body hair encompasses all other types (e.g., facial, underarm).
Process Overview
The laboratory evaluation of a drug test result comprises four principal phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the preliminary handling of a sample within a lab's framework. This step includes ensuring the sample's seal and shipment integrity, allocating a unique LAN (Laboratory Accessioning Number), and finalizing any outstanding documentation not captured by an electronic chain of custody protocol.
Screening includes an initial rapid assessment for drug residues. Though cost-efficient in ruling out substance intake across a majority of cases, positive screenings necessitate validation for legal acceptance. Any samples preliminarily tested as positive require subsequent confirmation testing.
Should a sample be initially positive during Screening, additional hair is extracted from the original sample for the Extraction phase. Here, substances are isolated from hair at much lower concentrations than other techniques (e.g., urine or saliva), making hair analysis the most complex to conduct.
The confirmation of any positive screening result is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All detected positive samples undergo a cleansing process before confirmation if necessary. The entire lab process, from Accessioning to Confirmation, adheres to both CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 certification.
