Hair Follicle Drug Testing - Berkeley, IL

What it is, How it works

Hair analysis is recognized as a robust method for detecting drug and alcohol consumption. Hair traps biomarkers within the fibers of the growing strand, offering a prolonged history of substance use. When obtained near the scalp, hair samples can reveal drug and alcohol use for up to approximately three months. Collection of hair is straightforward, challenging to tamper with, and convenient to transport.

A 1.5-inch hair sample, consisting of around 200 strands (roughly the thickness of a #2 pencil) nearest to the scalp, yields 100mg, the optimal amount for initial screening and confirmation tests. For EtG testing, extended panel tests, or tests over 10 panels, 150mg of the sample is preferred. Using a jeweler's scale to measure the specimen is advised. If scalp hair is not available, a similar quantity of body hair may be used. "Head hair" specifically refers to scalp hair, while "body hair" encompasses all other hair types (like facial and axillary hair).

Process Overview

The laboratory processing of drug test results involves four key stages: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, the initial handling of a sample within a laboratory system occurs. This step involves confirming that the sample was sealed and sent correctly, allocating a random Laboratory Accessioning Number (LAN), and completing any additional data entry not covered by an electronic chain of custody system.

Screening is a preliminary examination for drugs of abuse. Though cost-effective for negating drug usage in the majority of samples, a positive screen requires confirmation for legal admissibility. Samples with a presumptive positive result in Screening need further confirmation.

Should a sample yield a presumptive positive during Screening, more hair is extracted from the original specimen for Extraction. At this stage, drugs are extracted from hair in much lower concentrations than seen in other methods (such as urine or oral fluid), marking hair drug screening as one of the most challenging methodologies to execute.

Positive screening results are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleansed before confirmation, when necessary. The comprehensive lab process, from Accessioning to Confirmation, is evaluated under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Long detection window: Hair drug tests can trace drug use for up to 90 days, unlike urine tests which detect drugs for a shorter period.
• Difficulty to cheat: It is challenging to manipulate hair drug tests, leading to more reliable results.
• Provides historical data: It reveals a timeline of drug use over an extended period, rather than just recent use.

Limitations:

• Cannot detect recent use: Drugs become detectable in hair in roughly 5-7 days.
• Cost: Hair drug tests are typically pricier than other drug testing techniques.
• Variations in results: Elements like hair color and individual hair growth differences can influence drug metabolite concentrations in the hair.

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