Hair testing is recognized as a robust method for identifying drug and alcohol use. By capturing biomarkers within the strands of growing hair, it presents a comprehensive history of drug and alcohol consumption. When obtained near the scalp, hair can reveal substance use for approximately three months. The process of collecting hair is straightforward, challenging to tamper with, and convenient to transport.
A sample measuring 1.5 inches with about 200 hair strands (roughly the thickness of a #2 pencil) nearest the scalp yields 100mg, an optimal quantity for screening and confirmation. For EtG, add-ons, and/or tests beyond 10 panels, a 150mg sample is advisable. It is recommended to use a jeweler's scale for weighing the sample. In cases where scalp hair isn't available, an equivalent volume of body hair can be utilized. "Head hair" refers specifically to scalp hair, while "body hair" pertains to all other types (facial, underarm, etc.).
Process Overview
Drug test lab processing involves four key stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary step of incorporating a sample into a lab's system, involving verifying the sample's proper sealing and shipment, assigning a LAN (Laboratory Accessioning Number), and completing any data entry not provided by an electronic chain of custody system.
Screening entails a swift preliminary drug check. This initial stage can efficiently exclude drug use in most samples, yet any positive screen must be verified for legal admissibility. Presumptively positive samples require subsequent confirmation.
In cases where a sample returns a presumptive positive result during Screening, additional hair from the initial sample is collected for the Extraction process. During Extraction, drugs are separated from hair at much lower concentrations than other methods (e.g., urine or oral fluid), which is why hair drug screening is particularly challenging.
GC/MS, GC/MS/MS, or LC/MS/MS techniques confirm any positive screening outcomes. All presumptive positives undergo washing before confirmation as necessary. The lab process from Accessioning to Confirmation is thoroughly vetted under the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
