Hair Follicle Drug Testing - Knob Lick, MO

What it is, How it works

Hair analysis is increasingly recognized as an effective method for identifying drug and alcohol consumption. It offers extensive insights into alcohol and drug usage by locking biomarkers within the fibers of the burgeoning hair strand. When gathered close to the scalp, hair can provide a detection timeframe of nearly three months for alcohol and various drugs. Hair collection is straightforward, somewhat resistant to tampering, and simple to transport.

A 1.5-inch segment consisting of roughly 200 hair strands (similar in size to a #2 pencil) nearest the scalp yields 100mg of hair, which is the optimal quantity for both screening and verification. For tests involving EtG, additional screenings, and/or panels greater than 10, a specimen amount of 150mg is advised. It is advisable to measure the sample using a jeweler’s scale. In cases where scalp hair is not present, an equivalent mass of body hair may be collected. When mentioning head hair, we specifically refer to scalp hair. Body hair encompasses all other types (facial, axillary, etc.).

Process Overview

The laboratory processing of drug test results encompasses four primary actions: Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the initial integration of a sample into a laboratory’s apparatus. This covers verifying that the specimen was accurately sealed and couriered, assigning a random LAN (Laboratory Accessioning Number), and finalizing any necessary data entry absent from an electronic chain of custody protocol.

Screening is a preliminary brisk assessment for potential drugs of abuse. While Screening is economical for invalidating drug use throughout most samples, positive screenings necessitate validation to be considered court-admissible. Any specimen that appears positive in Screening mandates subsequent confirmation.

Should a sample show presumptive positivity during the Screening phase, additional hair is extracted from the primary specimen for Extraction. During this phase, drugs are removed from hair at notably lower concentrations than other methods (e.g., urine or oral fluid), highlighting why hair drug analysis is the most challenging technique to execute.

Verification of any positively screened results is executed through GC/MS, GC/MS/MS, or LC/MS/MS. All samples indicating presumptive positivity undergo a cleaning process before confirmation if required. The complete laboratory procedure, from Accessioning to Verification, is examined under CAP (College of American Pathologists) Hair designation alongside accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection range: Hair drug analyses can identify drug usage for up to 90 days, whereas urine tests possess a briefer detection range.
• Hard to manipulate: The difficulty in falsifying a hair drug analysis enhances result accuracy.
• Historic data provision: It can outline a drug use pattern over time, not just recent use.

Limitations:

• Incapable of identifying recent consumption: Drugs generally require about 5-7 days to appear in hair.
• Expense: Hair drug analyses tend to be costlier than other testing techniques.
• Result variations: Elements like hair color and individual hair growth rates can influence drug metabolite concentrations in hair.

Note: Although commonly called "hair follicle tests", the examination actually assesses the hair strand rather than the hair follicle beneath the scalp.
