Hair Follicle Drug Testing - North Barrington, IL

What it is, How it works

Hair analysis has emerged as an effective method for uncovering drug and alcohol consumption. The hair captures a prolonged record of alcohol and drug usage by embedding biomarkers within the fibers of the hair shaft. When taken near the scalp, hair tests can reveal drug and alcohol consumption over the past three months. Collecting hair samples is straightforward, fairly resistant to tampering, and convenient to transport.

A hair sample measuring 1.5 inches and comprising roughly 200 strands (comparable to a #2 pencil's thickness) nearest to the scalp will yield around 100mg of hair, providing an ideal amount for initial testing and verification. For EtG, additional tests, or tests exceeding 10 panels, it is advisable to use 150mg of the sample. Utilizing a jeweler’s scale is suggested for accurate measurement. In cases without scalp hair, a similar quantity of body hair may be used. The term "head hair" refers to scalp hair specifically, while "body hair" includes all other types (such as facial, underarm, etc.).

Process Overview

There are four principal phases in the laboratory analysis of a drug test: Accessioning, Screening, Extraction, and Confirmation.

Accessioning encompasses the primary processing of the sample into the lab system. Tasks include validating the proper sealing and shipping of the sample, assigning a unique LAN (Laboratory Accessioning Number), and entering any data not provided through an electronic chain of custody system.

Screening involves an initial rapid check for illicit substances. While it is a cost-effective strategy to discount drug use in most samples, a positive screen must be verified for legal acceptance. Samples that show presumptive positivity during Screening necessitate extra confirmation.

Should a sample show presumptive positivity at the Screening phase, more hair is pulled from the initial sample and readied for Extraction. In this phase, substances are isolated from the hair at a much lower concentration than other techniques (such as urine or saliva), making hair drug testing the most challenging technique to conduct.

Positive screening results are confirmed via GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positivity are washed before the confirmation process if necessary. The laboratory process from Accessioning to Confirmation undergoes review under both the CAP (College of American Pathologists) Hair designation and is accredited to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use up to 90 days back, unlike urine tests with shorter windows.
• Resistance to manipulation: Cheating on a hair drug test is exceedingly difficult, enhancing result accuracy.
• Tracks past usage patterns: Offers a chronological perspective of drug consumption instead of recent usage alone.

Limitations:

• Inability to identify recent consumption: Drugs typically become detectable in hair after 5 to 7 days.
• Expense: Hair drug tests are usually costlier than alternative drug testing techniques.
• Outcome variability: Elements like hair color and personal hair growth differences can influence drug metabolite concentration in hair.

Note: Despite being commonly termed "hair follicle tests", the actual test evaluates the hair strand, excluding the follicle beneath the scalp
