Hair Follicle Drug Testing - Gilark, LA

What it is, How it works

Hair analysis has emerged as a robust method for uncovering drug and alcohol use. The hair retains a lengthy record of alcohol and other drugs by embedding biomarkers within the fibers of the hair as it grows. When collected near the scalp, hair can reveal up to an approximate 3-month detection timeline for alcohol and drugs. Hair is straightforward to collect, fairly challenging to adulterate, and simple to transport.

A sample size of 1.5 inches, consisting of about 200 hair strands (comparable to the width of a #2 pencil) nearest the scalp provides 100mg of hair, which is the optimal sample size for both screening and confirmation. For EtG, add-ons, and tests exceeding 10 panels, a specimen amount of 150mg is suggested. It is advisable to measure the specimen's weight using a jeweler’s scale. If scalp hair isn't available, a similar quantity of body hair can be used. The term head hair specifically refers to scalp hair, whereas body hair includes all other types (such as facial, axillary, etc.).

Process Overview

Laboratory processing of drug tests involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the initial incorporation of a sample into a lab’s system, involving steps like ensuring the sample is sealed and shipped correctly, assigning a random LAN (Laboratory Accessioning Number), and completing additional data entry not covered by an electronic chain of custody system.

Screening entails a preliminary check for drugs of abuse. While Screening provides a cost-efficient approach to exclude drug usage for most samples, a positive screen requires confirmation for legal admissibility. Samples showing a presumptive positive in Screening necessitate a follow-up confirmation.

In cases where a sample tests presumptively positive during the Screening phase, additional hair is taken from the initial sample for the Extraction process. Here, drugs are isolated from hair at a much lower concentration compared to other methods (such as urine or oral fluid), rendering hair drug testing the most challenging method to conduct.

The Confirmation of any positive Screening result is performed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples testing presumptive positive undergo a washing step before confirmation as necessary. The complete lab process from Accessioning to Confirmation is evaluated in accordance with both CAP (College of American Pathologists) Hair designation and ISO/IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extensive detection period: Hair drug tests can identify drug use for up to 90 days, unlike urine tests which offer a brief detection window.
• Hard to manipulate: Cheating a hair drug test is challenging, enhancing result accuracy.
• Historical usage insight: Provides a usage pattern over time, rather than just recent consumption.

Limitations:

• Inability to detect recent consumption: It takes roughly 5-7 days for drugs to manifest in hair.
• Expense: Typically, hair drug tests incur higher costs compared to other methods.
• Result variation: Aspects such as hair color and individual hair growth differences can influence the drug metabolite levels in hair.

Note: Although commonly termed "hair follicle tests", the testing is conducted on the hair strand, not the folicle under the scalp.
