Hair Follicle Drug Testing - Enhaut, PA

What it is, How it works

Hair testing is now recognized as an effective method for identifying drug and alcohol consumption. Hair provides a comprehensive history of alcohol and drugs by encapsulating biomarkers within the fibers of the hair as it grows. When taken near the scalp, hair can offer a detection timeline of up to around three months for substances. Hair is easy to collect, moderately challenging to tamper with, and straightforward to transport.

A 1.5-inch section of approximately 200 hair strands (roughly the width of a #2 pencil) nearest to the scalp yields 100mg of hair, which is the preferred sample size for testing and verification. For EtG, additional substances, and/or tests exceeding 10 panels, a sample of 150mg is suggested. Using a jeweler’s scale to weigh the sample is advisable. If scalp hair isn't available, a comparable amount of body hair might be used. When mentioning head hair, we specifically mean scalp hair. Body hair refers to all other types (such as facial and underarm hair).

Process Overview

The primary stages in laboratory analysis of a drug test result include Accessioning, Screening, Extraction, and Confirmation.

Accessioning encompasses the initial processing of a sample within a lab's system. This step includes ensuring the sample was securely sealed and sent, allocating a random LAN (Laboratory Accessioning Number), and completing any extra data requirements not available through an electronic chain of custody procedure.

Screening encompasses a preliminary rapid analysis for drugs of abuse. Although Screening is a budget-friendly way to disregard drug usage in the bulk of samples, a positive screen requires verification to be valid in legal proceedings. Any samples showing presumptive positives during Screening necessitate additional confirmation.

Should a sample exhibit presumptive positives during Screening, more hair is extracted from the original sample for the Extraction phase. In this procedure, drugs are extracted from hair at markedly lower concentrations compared to different techniques (like urine or saliva), highlighting why hair drug screening represents the most challenging method to execute.

Any positive Screening outcomes are validated using GC/MS, GC/MS/MS, or LC/MS/MS. Before Confirmation, all presumptive positive samples are washed if needed. The whole lab procedure, from Accessioning to Confirmation, is scrutinized under the CAP (College of American Pathologists) Hair category and compliant with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection duration: Hair drug tests can reveal drug use for up to 90 days, unlike urine tests which have a shorter detection span.
• Hard to manipulate: It is exceptionally challenging to falsify a hair drug test, thus enhancing result accuracy.
• Delivers historical insight: It provides a timeline of drug use over time, not merely recent intake.

Limitations:

• No recent use detection: Drugs become detectable in hair in approximately 5-7 days.
• Expense: Hair drug tests are typically more costly compared to alternative methods.
• Result variabilities: Aspects such as hair color and personal hair growth rates can influence drug metabolite levels in hair.

Note: Although often termed "hair follicle tests", the test actually examines the hair strand, not the follicle under the scalp.
