Hair Follicle Drug Testing - Fairlee, MD

What it is, How it works

Hair testing is increasingly recognized as an effective method for identifying drug and alcohol use. Hair retains biomarkers in the strand fibers, offering an extended timeline of substance usage. When sampled near the scalp, hair can indicate alcohol and drug use over a span of roughly three months. The collection process is straightforward, challenging to tamper with, and convenient to transport.

A segment of hair measuring 1.5 inches with roughly 200 strands (comparable to the diameter of a #2 pencil) near the scalp weighs approximately 100mg, which is optimal for testing and validation. For EtG, additional tests, or panels beyond 10, it is advised to collect 150mg of hair. Utilizing a jeweler’s scale for weighing is suggested. If scalp hair cannot be obtained, a similar quantity of body hair may be used. References to head hair specifically denote scalp hair. All other hair types, such as facial or axillary, fall under the category of body hair.

Process Overview

The laboratory process for drug testing includes four primary phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial step whereby a sample is processed into the laboratory’s system. This step ensures the sample was correctly sealed and transported, a random LAN (Laboratory Accessioning Number) is assigned, and any supplementary data entry absent from an electronic chain of custody is completed.

Screening involves a preliminary assessment for drugs of abuse. Although Screening provides a cost-effective means of excluding drug use in most samples, positive results require confirmation for court validity. Any samples indicated as positive during Screening must undergo additional confirmation.

Upon a presumptive positive result during the Screening phase, additional hair is extracted from the original sample for the Extraction process. Here, drugs are isolated from hair at lower concentrations compared to other methods (e.g., urine or oral fluid), explaining why hair drug screening is notably challenging to perform.

Confirmation of any positive Screening result employs GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples with presumptive positives undergo washing before confirmation as necessary. The complete laboratory process, from Accessioning to Confirmation, is overseen under the CAP (College of American Pathologists) Hair designation and complies with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests identify drug use up to 90 days, in contrast to urine tests with shorter spans.
• Difficulty to falsify: Cheating a hair drug test is exceedingly difficult, enhancing result accuracy.
• History insight: It reveals a pattern of drug usage over time, not just recent activity.

Limitations:

• No detection of recent usage: Drugs are typically detectable in hair after 5-7 days.
• Expense: Hair drug tests are typically costlier than other testing options.
• Result variability: Aspects like hair color and individual growth differences can influence drug metabolite concentration in hair.

Note: Although commonly referred to as "hair follicle tests", the procedure evaluates the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

When comparing hair follicle testing to traditional urine tests in Fairlee, MD, hair testing emerges superior due to enhanced detection accuracy and reliability. Hair tests have a longer detection window, roughly 90 days, compared to a few days for urine tests, offering a more comprehensive overview of an individual's drug use.
