Hair Follicle Drug Testing - Thorn Hill, TN

What it is, How it works

Hair testing is acknowledged as an efficient method for identifying drug and alcohol consumption. By capturing biomarkers in the fibers of the hair shaft, hair offers a comprehensive history of alcohol and drug use. When cut near to the scalp, hair can provide an approximate detection period of up to 90 days for alcohol and drugs. Hair collection is straightforward, relatively resistant to tampering, and convenient for delivery.

An ideal sample consists of a 1.5-inch section, approximately equivalent to a #2 pencil eraser's thickness, yielding 100 mg of hair for analysis. For tests involving EtG, add-ons, or more than 10 panels, a 150 mg sample is advised. Using a jeweler’s scale for weighing the specimen is suggested. In situations where scalp hair is not accessible, a similar amount of body hair is an alternative. Head hair pertains solely to scalp hair, while body hair includes all other types (facial, armpit, etc.).

Process Overview

The laboratory process for generating a drug test result comprises four key stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the introductory phase where a sample is processed into a lab’s system. It involves confirming correct sealing and shipment of the specimen, assigning a random LAN (Laboratory Accessioning Number), and completing any necessary data entry absent in an electronic chain of custody system.

Screening serves as an initial assessment for drugs of abuse. Although cost-effective for dismissing drug usage in most samples, positive Screenings must be confirmed to be validated in court. Consequently, secondary confirmations are mandatory for any samples leaving Screening as presumptively positive.

If a sample is flagged as presumptively positive during Screening, additional hair is extracted from the initial sample for Extraction. During Extraction, drugs are obtained from the hair at concentrations comparatively lower than those in alternate methodologies (e.g., urine or saliva), highlighting the complexity of hair drug analysis.

Positive screening results undergo Confirmation through processes like GC/MS, GC/MS/MS, or LC/MS/MS. All samples that presumptively test positive receive a wash before confirmation if necessary. The overall laboratory sequence from Accessioning to Confirmation upholds both CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards accreditation.

Benefits of hair drug testing:

• Extended detection duration: Hair drug tests are capable of identifying drug presence for up to 90 days, surpassing the shorter span of urine tests.
• Resistance against tampering: The high difficulty level in cheating a hair drug test enhances result accuracy.
• Tracks usage history: It demonstrates drug use patterns over time, instead of merely recent use.

Challenges:

• Inability to detect recent consumption: Drugs in hair become detectable after about 5-7 days.
• Expense: Hair drug tests generally incur higher costs compared to alternative testing methods.
• Result variability: Drug metabolite concentrations in hair can vary based on hair color and personal differences in hair growth.

Note: Commonly branded as "hair follicle tests," the assessment examines the hair strand rather than the follicle beneath the scalp.
