Hair Follicle Drug Testing - Annapolis Neck, MD

What it is, How it works

Hair testing is increasingly regarded as an effective method for detecting drug and alcohol use. Hair offers a prolonged history of alcohol and drug exposure by encapsulating biomarkers within the strands' fibers. When hair is taken near the scalp, it can provide an approximate 3-month detection period for alcohol and drugs. Hair is easy to collect, relatively hard to tamper with, and convenient for shipping.

A 1.5-inch sample comprising nearly 200 hair strands (about the dimension of a #2 pencil) closest to the scalp yields 100mg of hair, which is the optimal amount for screening and confirming. For EtG, add-ons, and/or tests surpassing 10 panels, a recommendation of 150mg is provided. It is advised to measure the specimen using a jeweler’s scale. If scalp hair is inaccessible, a corresponding quantity of body hair can be utilized. References to head hair imply scalp hair exclusively. Body hair encompasses all other varieties (facial, axillary, etc.).

Process Overview

The four central steps in the lab handling of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the preliminary processing of a sample into a laboratory's systems. It entails verifying the proper sealing and shipment of the sample, assigning a random LAN (Laboratory Accessioning Number), and finalizing any additional data entry not covered by an electronic chain of custody system.

Screening incorporates an initial rapid assessment for drugs of abuse. Though Screening serves as a cost-efficient method to negate drug use in most samples, a screen returning positive must undergo confirmation for court credibility. All samples yielding a presumptive positive during Screening need further confirmation.

Should a sample be presumptively positive during the Screening phase, additional hair is extracted from the original specimen and prepared for Extraction. Here, drugs are isolated from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), underscoring hair drug screening as the most challenging approach to execute.

Confirmation of any positive screening result is executed using GC/MS, GC/MS/MS, or LC/MS/MS. Every presumptive positive sample is cleansed before confirmation as necessary. The complete lab process from Accessioning to Confirmation is supervised under both the College of American Pathologists (CAP) Hair designation and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair tests can discern drug use up to 90 days, unlike urine tests with a briefer detection span.
• Improbability of deception: Cheating on a hair drug test is quite challenging, enhancing the accuracy of results.
• Provides historical insight: It depicts a pattern of drug consumption over a time frame, not solely recent usage.

Limitations:

• Inability to detect recent use: Drugs become noticeable in hair approximately after 5-7 days.
• Expense: Generally, hair drug tests are costlier than other drug testing techniques.
• Result variability: Aspects like hair color and individual differences in hair growth can influence drug metabolite levels in the hair.

Note: While often labeled as "hair follicle tests", the examination actually analyzes the hair strand and not the follicle beneath the scalp
