Hair Follicle Drug Testing - Langleyville, IL

What it is, How it works

Hair analysis has become recognized as an effective method for identifying alcohol and drug consumption. Hair can capture a comprehensive, long-term record of substance use by embedding biomarkers within its fibers as it grows. When sampled near the scalp, hair can reveal up to a three-month detection period for alcohol and drugs. Hair collection is straightforward, hard to tamper with, and simple to transport.

A sample measuring 1.5 inches in length, consisting of around 200 hairs (approximately the circumference of a #2 pencil) near the scalp, yields 100mg of hair, which is ideal for both initial and confirmatory testing. For EtG, additional tests, or panels exceeding 10, 150mg is advised. It is recommended to use a jeweler’s scale to measure the sample. If scalp hair is unavailable, an equivalent amount of body hair can be utilized. "Head hair" specifically denotes scalp hair. Conversely, "body hair" pertains to all other types including facial and axillary hair.

Process Outline

The key stages in the laboratory analysis of a drug test result include Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial phase of processing a sample within a laboratory’s framework, ensuring the sample is properly sealed and dispatched, assigning a unique LAN (Laboratory Accessioning Number), and finalizing any further data entry needed outside an electronic chain of custody system.

Screening entails a preliminary assessment for drugs of abuse. Although an economical approach to eliminate drug use in most samples, a positive screening must be validated for legal use. Samples preliminarily tested positive require additional confirmation.

In cases of presumptive positivity during Screening, further hair is extracted from the original sample for the Extraction process. Here, drugs are isolated from hair at much lower concentrations compared to other methods (e.g., urine or oral fluid), making hair drug screening a complex procedure.

Confirmation of any positive screening result uses GC/MS, GC/MS/MS, or LC/MS/MS techniques. All initially positive samples undergo washing prior to confirmation if necessary. The entire laboratory process from Accessioning to Confirmation is scrutinized under both CAP (College of American Pathologists) Hair designation and adherence to ISO / IEC 17025 standards.

Benefits of hair drug testing:

• Extended detection period: Hair tests can reveal drug use for up to 90 days, unlike urine tests which have a briefer detection span.
• Challenge to fraud: It's extremely difficult to falsify a hair test, enhancing result reliability.
• Offers historical insight: It can uncover patterns of drug consumption over time, not merely recent usage.

Drawbacks:

• Inability to detect recent use: Drugs become detectable in hair approximately 5-7 days post-use.
• Expense: Hair drug testing typically costs more than other testing methods.
• Result variability: Aspects like hair color and individual growth rates can influence drug metabolite concentration in hair.

Note: Despite being called "hair follicle tests," the analysis is performed on the hair strand rather than the follicle beneath the scalp.
