Hair Follicle Drug Testing - Leitch, MD

What it is, How it works

The use of hair testing has become recognized as an effective method for identifying drug and alcohol consumption. Hair captures a long-term record of substance use by incorporating biomarkers within the strands as they grow. By taking samples near the scalp, hair testing can offer an approximately 3-month detection period for alcohol and other drugs. The collection process for hair samples is straightforward, challenging to tamper with, and convenient for shipping.

A sample measuring 1.5 inches and consisting of roughly 200 hair strands (similar in size to a #2 pencil) near the scalp provides 100mg of hair, which is optimal for both screening and confirmation. For EtG, add-on tests, or tests exceeding 10 panels, it’s advisable to use 150mg of the sample. Utilizing a jeweler’s scale for specimen weighing is recommended. If scalp hair cannot be obtained, a similar amount of body hair may serve as an alternative. References to head hair pertain strictly to scalp hair, whereas body hair encompasses all other types (such as facial and axillary hair).

Process Overview

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

Accessioning entails the preliminary incorporation of a sample into a laboratory's system. This step verifies the appropriate sealing and shipping of the sample, assigns a random LAN (Laboratory Accessioning Number), and completes any necessary data entry not facilitated by an electronic chain of custody system.

Screening involves an initial rapid assessment for drugs of abuse. While screening serves as an economical means to rule out usage across most samples, positive screens require confirmation for legal admissibility. Any samples yielding a presumptive positive from screening necessitate subsequent confirmation.

If a sample is suspected to be positive during the Screening phase, additional hair is sourced from the primary specimen for the Extraction phase. During extraction, drugs are isolated from hair at concentrations significantly lower than those detected via other methodologies (e.g., urine or oral fluid). Consequently, performing hair drug testing poses greater complexity.

The Confirmation stage for any positive screening results uses GC/MS, GC/MS/MS, or LC/MS/MS techniques. Post-screening positives undergo washing as necessary before confirmation. The entire procedure, from Accessioning through Confirmation, aligns with CAP (College of American Pathologists) Hair criteria and conforms to ISO/IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug screenings can identify drug use for up to three months, contrasted with urine tests having shorter detection spans.
• Resistance to cheating: The difficulty in falsifying a hair drug test contributes to the reliability of its results.
• Historical substance use data: Hair testing reveals a timeline of drug consumption, rather than recent solitary usage.

Limitations:

• Inability to detect recent consumption: Drugs take about 5-7 days to become evident in hair.
• Expense: Hair drug tests tend to incur higher costs compared to alternative testing methods.
• Result variability: Factors including hair color and individual growth rate can influence drug metabolite concentrations in the hair.

Note: Although commonly termed as "hair follicle tests," these tests analyze the hair strand itself, not the follicle beneath the scalp.
