Hair Follicle Drug Testing - Neavitt, MD

What it is, How it works

Hair analysis is increasingly recognized as an effective means of detecting drug and alcohol use. Hair captures a long-term record of drugs and alcohol by embedding biomarkers in the strands as they grow. When obtained near the scalp, it offers a detection period of roughly three months for alcohol and drugs. Hair collection is straightforward, challenging to tamper with, and easily transported.

A sample of 1.5 inches consisting of around 200 hair strands (approximating a #2 pencil's size) nearest to the scalp amounts to 100mg, which is ideal for initial tests and confirmations. For EtG, additional tests, and/or those exceeding 10 panels, a specimen of 150mg is advisable. Using a jeweler’s scale for weighing the sample is suggested. If scalp hair is not accessible, an equivalent quantity of body hair may be utilized. When we mention head hair, it is specifically scalp hair. Body hair encompasses all other types (such as facial and axillary hair).

Process Overview

The laboratory process for a drug test follows four key steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the step for the initial integration of a specimen into the lab's system. This process ensures that the specimen is properly sealed and shipped, assigns an anonymous Laboratory Accessioning Number (LAN), and includes any extra data entry that an electronic chain of custody system might not provide.

Screening involves a preliminary quick assessment for drugs of abuse. While Screening is a cost-effective method to exclude drug use across most samples, it is crucial for positive screens to undergo confirmation to be viable in court. Any samples that show positive in Screening need a follow-up confirmation.

When a sample seems positive in Screening, additional hair is extracted from the original specimen and refined for Extraction. This phase extracts drugs from hair at concentrations lower than those in other testing strategies (like urine or saliva), making hair drug screening the most complex method to execute.

Confirmation of any Screening positives is done through GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives undergo washing before confirmation if necessary. The comprehensive laboratory check from Accessioning to Confirmation is conducted under both the CAP (College of American Pathologists) Hair recognition and the ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can reveal drug usage for up to 90 days, unlike urine tests that have a more limited detection timeframe.
• Hard to manipulate: Hair drug tests are tough to cheat, hence providing more reliable outcomes.
• Offers historical insights: It offers a usage pattern over time, rather than only recent usage.

Limitations:

• Incapable of detecting recent consumption: It generally takes 5-7 days for drugs to become detectable in hair.
• Expense: Hair drug testing is often pricier compared to other drug testing approaches.
• Result variability: Elements like hair color and individual hair growth differences can influence drug metabolite levels in hair.

Note: Although commonly known as "hair follicle tests", these actually analyze the hair shaft rather than the follicle beneath the scalp.
