Hair Follicle Drug Testing - Lightstreet, PA

What it is, How it works

Hair analysis has emerged as a potent method for identifying drug and alcohol usage. Hair can hold a long-term record of substances by capturing biomarkers within its growing strands. When taken near the scalp, it can offer a detection window of around three months for alcohol and other substances. The collection of hair samples is straightforward, relatively tamper-proof, and easy to transport.

A 1.5-inch section from about 200 hair strands (roughly the width of a #2 pencil) near the scalp yields 100 mg of hair, which is the optimal amount for both initial screening and verification. For EtG testing, additional panels, or profiles above 10 panels, 150 mg of the sample is advisable. It's beneficial to weigh the hair specimen using a jeweler’s scale. In cases where scalp hair cannot be sourced, a comparable amount of body hair is acceptable. When discussing head hair, we specifically mean scalp hair, while body hair pertains to other hair types (like facial or axillary).

Process Overview

The laboratory processing of a drug analysis consists of four major steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning denotes the initial phase of entering a sample into a lab’s system. This procedure ensures that the sample was appropriately sealed and transported, assigns a unique LAN (Laboratory Accessioning Number), and fills in any data entry gaps not covered by an electronic chain of custody system.

Screening serves as a preliminary method to identify drugs of abuse. While Screening is a cost-efficient way to exclude drug use in the majority of samples, a positive indication in Screening necessitates confirmation for court validity. Any samples hinting at positivity in Screening require further verification.

If Screening suggests a sample is positive, additional hair is prepared from the initial batch for Extraction. This stage involves extracting drugs from the hair at significantly lower concentrations compared to other methods (such as urine or oral fluid), which renders hair drug testing the most challenging to conduct.

Confirmation of any Screening positive is performed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All tentative positive samples undergo washing before confirmation if necessary. The entire lab process, from Accessioning to Confirmation, is evaluated under CAP (College of American Pathologists) Hair guidelines and is accredited to ISO / IEC 17025 specifications.

Advantages of hair drug testing:

• Long detection window: Hair drug tests can capture drug use for as long as 90 days, unlike urine tests which have a more limited timeframe.
• Immunity to tampering: Cheating a hair drug test is notably hard, enhancing result reliability.
• Timeline of usage: It can indicate a user’s drug usage pattern over time, not merely recent use.

Limitations:

• Incapable of detecting immediate past use: It takes around 5-7 days for drugs to appear in hair samples.
• Expense: Hair drug tests typically incur higher costs than alternative drug testing approaches.
• Result inconsistency: Variables like hair color and individual hair growth differences can influence drug metabolite levels in hair.

Note: Commonly referred to as "hair follicle tests", the actual examination focuses on the hair strand and not the follicle beneath the skin.
