Urine| Hair Follicle | Oral Fluid | Blood | ETG
The analysis of hair has emerged as an effective method for detecting drug and alcohol consumption. Hair maintains a prolonged history of substances by embedding biomarkers in its fibers as it grows. By collecting hair close to the scalp, it can reveal a detection timeframe of up to roughly three months for drugs and alcohol. Hair collection is straightforward, challenging to tamper with, and easily transportable.
A 1.5-inch segment of nearly 200 hair strands (approximately the size of a #2 pencil) that is nearest to the scalp yields 100mg, which is ideal for testing and verification. For EtG, additional tests, and panels over ten, a sample of 150mg is suggested. It's advisable to measure the specimen on a jeweler's scale. If scalp hair cannot be obtained, an equal quantity of body hair is acceptable. "Head hair" specifically refers to scalp hair, while "body hair" encompasses all other types (facial, axillary, etc.).
Process Overview
Key stages in lab processing of drug testing include Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the preliminary integration of a sample into a lab's system. This process includes confirming the sample was properly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and completing any outstanding data entry not managed by an electronic custody chain system.
Screening provides an initial sweep for substances of abuse. Although Screening is cost-effective for ruling out substance intake for most samples, a positive screen must be verified for court admissibility. Samples with presumptive positives in Screening require subsequent confirmation.
If the initial Screening indicates a presumptive positive, further hair is extracted from the original sample for the Extraction phase. Here, substances are isolated from hair at significantly lower concentrations than in alternatives like urine or oral fluid, making hair screening the most intricate methodology.
Confirmation of any positive screening is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positives undergo washing before confirmation as necessary. The laboratory sequence from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Limitations:
Note: Though commonly termed "hair follicle tests", the assessment examines the hair strand, not the scalp's follicle.
