Hair Follicle Drug Testing - Joppatowne, MD

What it is, How it works

Hair analysis is increasingly recognized as an effective means for identifying drug and alcohol consumption. Hair captures a long-standing record of substance use by embedding biomarkers within the fibers as the hair grows. When taken near the scalp, hair can offer a detection timeline of up to three months for alcohol and drugs. Hair collection is straightforward, somewhat resistant to tampering, and simple to send.

A 1.5-inch strand bundle, roughly 200 hairs thick (similar in diameter to a #2 pencil), close to the scalp yields 100mg of hair, the preferred amount for analysis and verification. For EtG, supplements, and/or assessments exceeding 10 panels, 150mg of the sample is advisable. It is best practice to weigh the sample on a jeweler’s scale. If scalp hair is inaccessible, a comparable amount of body hair is permissible. In discussions about head hair, we mean exclusively scalp hair. Body hair pertains to alternate types (facial, axillary, etc.).

Process Overview

The four core procedures in the lab analysis of a drug test result include Accessioning, Screening, Extraction, and Confirmation.

Accessioning deals with the sample's entry into the laboratory's database. This encompasses confirming that the sample was properly sealed and sent, assigning a random LAN (Laboratory Accessioning Number), and finishing any data input not covered by an electronic chain of custody system.

Screening involves a preliminary swift review for drug abuse markers. Although Screening is an economical path to exclude drug use in the majority of samples, a positive result necessitates additional confirmation for legal acceptance. Any samples that seem positive at Screening require a further confirmation step.

Should a sample appear positive during Screening, additional hair is taken from the main sample and prepped for Extraction. Here, drugs are drawn from the hair at a significantly lower density than in other methods (such as urine or oral fluids), which renders hair drug screening the most challenging methodology to execute.

Confirmation of any positive screening outcome is executed using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo cleansing before confirmation if necessary. The complete lab sequence from Accessioning to Confirmation is inspected under the CAP (College of American Pathologists) Hair designation and the adherence to ISO / IEC 17025 criteria.

Advantages of hair drug testing:

• Extended detection duration: Hair drug screenings can uncover drug use for up to 90 days, unlike urine tests which have a shorter timeframe.
• Challenging to deceive: Hair drug tests are hard to falsify, thereby improving accuracy.
• Yields historical insights: It details patterns of drug usage over a duration, rather than just the recent use.

Limitations:

• Incapable of identifying recent use: Drugs become detectable in hair after approximately 5-7 days.
• Expense: Hair drug tests tend to be pricier than alternative drug testing techniques.
• Result discrepancies: Factors like hair color and personal growth variations can impact the amount of drug metabolites in the hair.

Note: Even though termed "hair follicle tests", the examination assesses the hair strand and not the follicle beneath the scalp.
