Hair Follicle Drug Testing - Cale, AR

What it is, How it works

Hair analysis is widely recognized as an effective method for identifying drug and alcohol consumption. Hair retains long-term markers of alcohol and drug use by embedding biomarkers within the hair's fibers as it grows. When hair is sampled near the scalp, it can reveal drug and alcohol usage over an approximately three-month timeframe. Hair collection is straightforward, hard to tamper with, and convenient to transport.

A sample measuring 1.5 inches, comprising roughly 200 hair strands (about the diameter of a #2 pencil) nearest the scalp, will yield 100mg of hair, which is ideal for screening and corroboration. For EtG, additional analyses, and/or over 10-panel tests, a 150mg sample is advised. It's suggested to weigh the sample using a jeweler's scale. If scalp hair isn't accessible, a similar quantity of body hair can be used. "Head hair" specifically refers to scalp hair, whereas "body hair" includes all other hair types (facial, axillary, etc.).

Process Overview

The core procedures within the laboratory examination of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.

Accessioning consists of the initial handling of a specimen within a laboratory's framework. This encompasses confirming the sample was correctly sealed and sent, designating a random LAN (Laboratory Accessioning Number), and completing any extra data entries absent in an electronic chain of custody framework.

Screening offers an initial rapid assessment for drug misuse. While it is an economical method to dismiss drug usage in most samples, a positive screen requires validation to be court-admissible. Samples that test initially positive in Screening necessitate further confirmation.

If a sample shows preliminary positivity in the Screening phase, additional hair is extracted from the initial sample and readied for Extraction. This phase involves isolating drugs from hair at notably lower concentrations than in other methods (e.g., urine or oral fluid), which is why hair drug testing is considered more complex.

Confirmation of any positive screening outcome is performed using GC/MS, GC/MS/MS, or LC/MS/MS methodologies. All presumptive positive specimens undergo washing before confirmation as necessary. The complete laboratory procedure from Accessioning to Confirmation is subject to review under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests can identify drug use for up to 90 days, unlike urine tests which have a shorter detection period.
• Challenging to manipulate: It is quite challenging to deceive a hair drug test, making the findings more credible.
• Offers historical insight: It provides a drug usage pattern over time, not limited to recent consumption.

Limitations:

• Inability to identify recent use: Drugs take about 5-7 days to become detectible in hair.
• Expense: Hair drug tests typically cost more than other drug testing techniques.
• Result variability: Factors like hair color and individual hair growth rates can influence drug metabolite concentrations in hair.

Note: Commonly referred to as "hair follicle tests", the examination actually involves analyzing the hair strand, not the follicle beneath the scalp

Why Hair Follicle Testing Beats Urine Testing
