Hair Follicle Drug Testing - Horn, AZ

What it is, How it works

Hair testing has emerged as a potent instrument for uncovering drug and alcohol consumption. Hair provides an extended timeline of alcohol and drug history by encapsulating biomarkers within the strands of the developing hair. When sourced from near the scalp, hair can offer a detection timeframe of up to roughly 3 months for alcohol and drugs. Hair is straightforward to gather, relatively hard to tamper with, and easy to transport.

A sample of 1.5 inches consisting of approximately 200 hair strands (about the diameter of a #2 pencil) closest to the scalp fulfills the requirement of 100mg of hair, which is the optimal sample for testing and validation. For EtG, supplementary, and/or tests exceeding 10 panels, 150mg of the specimen is advisable. It is suggested to measure the specimen using a jeweler's scale. In the absence of scalp hair, an equivalent quantity of body hair can be utilized. When discussing head hair, it specifically refers to scalp hair. Body hair denotes all other hair varieties (facial, axillary, etc.).

Process Overview

The principal phases in the lab processing of a drug test result encompass Accessioning, Screening, Extraction, and Confirmation.

Accessioning embraces the initial stage of processing a sample into the lab's protocol. This involves affirming that the sample was properly sealed and dispatched, allotting a random LAN (Laboratory Accessioning Number), and completing any additional data entry not provided by an electronic chain of custody system.

Screening entails an initial swift examination for drugs of abuse. Though Screening offers a cost-efficient method to rule out drug consumption in the majority of cases, a positive screen necessitates confirmation for court admissibility. Presumptive positive samples in Screening mandate further confirmation.

Should a sample be deemed presumptively positive in the Screening phase, additional hair is extracted from the initial specimen and readied for Extraction. This phase involves extracting drugs from hair at a significantly lower concentration than other techniques (e.g., urine or oral fluid), underscoring why hair drug testing is the most challenging methodology to conduct.

Confirmation of any positive outcome from screening is carried out via GC/MS, GC/MS/MS, or LC/MS/MS. Every presumptive positive sample undergoes washing prior to confirmation as needed. The complete laboratory process from Accessioning through Confirmation is assessed under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can trace drug consumption for up to 90 days, unlike urine tests which offer a shorter detection period.
• Difficult to deceive: Cheating a hair drug test is remarkably tough, ensuring more accurate results.
• Provides historical insights: It can reveal a drug usage pattern over an extended duration, beyond just recent consumption.

Limitations:

• Cannot identify recent consumption: Detection in hair takes roughly 5-7 days post-drug use.
• Expense: Hair drug tests typically cost more than other drug testing techniques.
• Result variability: Hair color and personal hair growth differences can influence drug metabolite concentrations in hair.

Note: Although commonly dubbed "hair follicle tests", the evaluation actually involves analyzing the hair strand, not the follicle beneath the scalp.
