Hair Follicle Drug Testing - Bonnie Doone, NC

What it is, How it works

Hair analysis has gained recognition as an effective means for detecting drug and alcohol consumption. Hair captures a chronological record of substances by embedding biomarkers within the strands of hair as they grow. Collected near the scalp, hair reveals a detection period of up to three months for alcohol and drugs. Hair collection is straightforward, hard to tamper with, and easy to transport.

A sample size of 1.5 inches consisting of around 200 hair strands (approximately the diameter of a #2 pencil) near the scalp yields 100mg of hair, which is optimal for screening and confirmation. For EtG, additional assessments, and tests exceeding 10 panels, a specimen amounting to 150mg is advised. Using a jeweler’s scale to measure the specimen is suggested. In the absence of scalp hair, equivalent body hair may be collected. The term "head hair" refers exclusively to scalp hair, while "body hair" encompasses all other types (facial, axillary, etc.).

Process Overview

The lab processing of a drug test result comprises four main steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the preliminary procedure of integrating a sample into the laboratory’s framework. It involves verifying the proper sealing and shipping of the sample, assigning an arbitrary Laboratory Accessioning Number (LAN), and carrying out any supplementary data entry absent in an electronic chain of custody system.

Screening offers an initial rapid assessment for drug abuse. Although cost-effective in excluding drug use in most samples, a positive screening result necessitates confirmation for legal acceptance. Presumptive positives in Screening mandate subsequent confirmation.

Upon obtaining a presumptive positive result during Screening, additional hair is extracted from the original specimen for the Extraction phase. This stage distinguishes drugs from hair at significantly reduced concentrations compared to other techniques (e.g., urine or oral fluid), highlighting the complexity of hair drug screening.

Positive screening results undergo Confirmation using GC/MS, GC/MS/MS, or LC/MS/MS. Necessitated presumptive positive samples are cleaned before confirmation. The entire process from Accessioning to Confirmation undergoes evaluation under the CAP (College of American Pathologists) Hair criteria and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection timeframe: Hair drug testing identifies drug usage encompassing a 90-day span, unlike urine testing with a brief detection period.
• Resistance to manipulation: Hair drug tests are challenging to falsify, enhancing result accuracy.
• Offers historical insight: It reflects a pattern of drug use over time, rather than recent usage alone.

Limitations:

• Delayed recent use detection: Drugs require approximately 5-7 days to appear in hair.
• Expense: Hair drug tests are typically costlier than other drug testing methods.
• Result variability: Influences like hair color and individual hair growth variations can alter drug metabolite concentrations in hair.

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