Hair Follicle Drug Testing - Carlos, MD

What it is, How it works

The utilization of hair testing has gained prominence as an effective technique for identifying drug and alcohol consumption. Hair contains a prolonged history of alcohol and other substances by capturing biomarkers within the fibers of the developing hair strand. When acquired from near the scalp, hair can offer a detection time frame of up to roughly three months for alcohol and other substances. Hair is straightforward to obtain, relatively hard to tamper with, and convenient to transport.

A 1.5-inch section comprising approximately 200 hair strands (roughly the thickness of a #2 pencil) nearest to the scalp will yield 100 mg of hair, the optimal sample size for both preliminary and confirmatory testing. For EtG, supplementary assessments, and/or panels exceeding 10, 150 mg of the sample is suggested. It is advisable to measure the sample using a jeweler’s scale. If scalp hair is lacking, an equivalent quantity of body hair can be gathered. References to head hair specifically denote scalp hair. Body hair encompasses all other forms of hair (facial, axillary, etc.).

Process Overview

The lab analysis of a drug test outcome involves four principal stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning constitutes the sample's initial processing within a lab's system. This process verifies the proper sealing and shipping of the sample, assigns a unique LAN (Laboratory Accessioning Number), and finalizes any additional data not captured by an electronic chain of custody framework.

Screening is a preliminary rapid assessment for substances of abuse. Although Screening is a budget-friendly approach for excluding drug use in most samples, a positive screen must be validated to be permissible in a legal context. Samples that are presumptively positive during Screening necessitate further confirmation.

Upon obtaining a presumption of positivity in Screening, more hair is extracted from the original sample for the Extraction stage. Here, drugs are isolated from hair at significantly lower concentrations than with other methods (e.g., urine or oral fluid), contributing to the elevated complexity of hair drug screening as a methodology.

Confirmation of any presumptive positive screening result is achieved via GC/MS, GC/MS/MS or LC/MS/MS. All samples presumed positive are rinsed prior to confirmation if required. The comprehensive lab process, from Accessioning to Confirmation, is assessed under the auspices of both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can reveal drug consumption for as long as 90 days, unlike urine tests which have a more limited detection period.
• Challenge to falsify: It is quite challenging to falsify a hair drug test, resulting in more reliable findings.
• Historical insight: It offers a drug use timeline spanning over an extended period, surpassing merely recent usage assessment.

Limitations:

• Inability to detect recent usage: It generally takes approximately 5-7 days for substances to become detectable in hair.
• Expense: Hair drug tests generally involve higher costs than alternative drug testing methods.
• Result variations: Variables like hair color and individual differences in hair growth can influence the concentration of drug metabolites within the hair.

Note: Despite often being termed as "hair follicle tests", the test evaluates the hair strand itself rather than the hair follicle beneath the scalp.
