Hair Follicle Drug Testing - Green Hills, PA

What it is, How it works

Hair testing is recognized as an effective method for identifying drug and alcohol consumption. It records a prolonged history of substances like alcohol by embedding biomarkers within the fibers of the hair strand. When the hair is collected near the scalp, it can reveal approximately a 3-month detection timeline for drugs and alcohol. Hair collection is straightforward, fairly tamper-resistant, and easy to transport.

A sample of 1.5 inches of around 200 hair strands (approximately the diameter of a #2 pencil) taken nearest the scalp yields 100mg, which is perfect for both initial testing and confirmation. For EtG, supplementary tests, or panels exceeding 10, a specimen of 150mg is suggested. It's advisable to measure the sample using a jeweler’s scale. If there's no scalp hair, an equivalent quantity of body hair might be sourced. Note that head hair refers solely to scalp hair, while body hair encompasses all other varieties (such as facial, armpit, etc.).

Process Overview

There are four principal phases in processing a drug test in the lab: Accessioning, Screening, Extraction, and Confirmation.

Accessioning deals with the primary steps of integrating a sample into a lab's system. This process checks that the sample is sealed and dispatched correctly, assigns a unique LAN (Laboratory Accessioning Number), and handles any data input missing in an electronic chain of custody system.

Screening offers a basic preliminary check for substance abuse. While it's a cost-effective strategy to eliminate drug use for most samples, any positive outcome necessitates confirmation to ensure courtroom admissibility. Presumptive positives in Screening must go through secondary validation.

If a sample tests positive in Screening, additional hair is extracted from the sample and readied for Extraction. During this phase, the concentration of drugs removed from hair is significantly lower than with other techniques (e.g., urine or oral fluid), emphasizing why hair drug screening is challenging.

For positive screening results, Confirmation is executed using GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all presumptive positive samples are often washed as needed. The complete laboratory procedure from Accessioning to Confirmation is carried out with oversight under CAP (College of American Pathologists) Hair criteria and in line with ISO/IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection duration: Hair drug tests track drug usage up to 90 days, whereas urine tests detect a shorter usage timeframe.
• Cheating is difficult: Hair drug tests are tough to cheat, providing more reliable results.
• Establishes historical usage: It showcases a timeline of drug usage over a prolonged time frame, not solely recent activity.

Limitations:

• Unable to identify recent usage: Drugs generally take 5-7 days to become traceable in hair.
• Expense: Hair drug testing usually costs more than some other drug test techniques.
• Result variability: Elements like hair color and individual hair growth differences can influence the concentration of drug indicators in hair.

Note: Although sometimes termed "hair follicle tests", the analysis focuses on the hair strand, not the follicle beneath the scalp.
