Hair Follicle Drug Testing - Equality, IL

What it is, How it works

Hair testing has emerged as a robust method for identifying drug and alcohol consumption. It offers a comprehensive history of substance use by capturing biomarkers within the fibers of hair strands as they grow. When obtained near the scalp, hair can reveal substance use over an approximately 3-month period for both alcohol and other drugs. Hair collection is straightforward, less susceptible to tampering, and easy to transport.

A 1.5-inch segment of roughly 200 hair strands (comparable to the diameter of a #2 pencil) closest to the scalp provides about 100mg of hair, which is ideal for both screening and confirmation. When testing for EtG, using add-ons, or when exceeding 10 panels, a specimen of 150mg is advisable. It is suggested to weigh this on a jeweler's scale. Should scalp hair be unavailable, an equivalent amount of body hair can be sampled. The term head hair refers specifically to scalp hair, while body hair encompasses all other forms (such as facial or axillary hair).

Process Overview

The laboratory processing of a drug test result involves four primary stages: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, the sample is initially processed into the laboratory system. This includes ensuring the sample was securely sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and completing any missing data entry not captured through an electronic chain of custody system.

Screening is a preliminary assessment for drugs of abuse. It is a cost-effective approach to exclude drug usage in most samples, but a positive result needs confirmation for legal acceptance. Samples that screen positive initially require subsequent confirmation.

If a sample tests presumptively positive during Screening, additional hair is extracted from the original specimen for Extraction. At this stage, drugs are isolated from hair at levels much lower than in other methods (e.g., urine or oral fluid), contributing to the complexity of hair drug screening methodologies.

To confirm any positive screening results, techniques such as GC/MS, GC/MS/MS, or LC/MS/MS are used. Samples with presumptive positive results are washed before confirmation as necessary. The complete laboratory process, from Accessioning to Confirmation, is scrutinized under both the CAP (College of American Pathologists) Hair designation and adheres to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests can identify drug usage for up to 90 days, whereas urine tests have a shorter detection period.
• Cheating is difficult: The accuracy of hair drug tests is heightened due to the challenge of tampering with the evidence.
• Historical usage pattern: They reflect a history of drug use over a span of time, unlike tests that only detect recent usage.

Limitations:

• Unable to detect recent usage: It requires about 5-7 days for drugs to become detectable in hair.
• Expense: Typically, hair drug tests cost more than other testing methodologies.
• Result variability: Elements like hair color and individual differences in hair growth can influence metabolite concentration in hair.

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