Hair analysis has gained recognition as an effective means for revealing alcohol and drug consumption. By capturing biomarkers within the hair shaft's fibers, hair offers a prolonged snapshot of substance use. When taken near the scalp, it can reveal drug and alcohol presence for up to roughly three months. Hair collection is straightforward, challenging to tamper with, and convenient for transportation.
A portion of hair measuring 1.5 inches, consisting of about 200 strands (similar to the thickness of a #2 pencil) from near the scalp, equates to 100mg—the preferred quantity for analysis. For EtG, add-ons, and/or evaluations exceeding 10-panel tests, 150mg is advisable. We advocate using a jeweler’s scale for specimen measurement. If scalp hair is not an option, gather an equivalent volume of body hair. References to head hair imply solely scalp hair. In contrast, body hair encompasses all other hair categories (facial, axillary, etc.).
Process Overview
The laboratory processing of drug test outcomes is comprised of Accessioning, Screening, Extraction, and Confirmation as primary steps.
Accessioning entails the preliminary integration of samples into the lab's framework. This entails ensuring the sample's sealing and proper shipment, generating a unique LAN (Laboratory Accessioning Number), and undertaking any supplementary data input that an electronic chain of custody hasn't already provided.
Screening provides an initial rapid assessment for drug presence. Although Screening offers a budget-friendly approach to negate drug usage in most samples, a positive result necessitates confirmation to hold up in court. Samples suspected positive during Screening mandate an additional verification.
Should a sample indicate tentative positivity during Screening, additional hair from the original collection is utilized for Extraction. At this juncture, substances are isolated from hair at markedly lower levels than seen in other methods (e.g., urine or oral fluids), rendering hair drug analysis highly challenging to execute.
Verification of any positive screening finds completion via GC/MS, GC/MS/MS, or LC/MS/MS. Prior to verification, washing of any presumed positive samples is done when required. The lab process spanning from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair designation along with the ISO/IEC 17025 standard accreditation.
