Hair Follicle Drug Testing - Potomac, MD

What it is, How it works

Hair analysis is recognized as a potent method for identifying drug and alcohol use. Hair offers an extensive historical record of alcohol and drugs by embedding biomarkers in the strands of growing hair. When gathered near the scalp, hair can deliver up to a 3-month detection period for alcohol and drugs. It's easy to collect, hard to tamper with, and simple to send.

A sample measuring 1.5 inches, comprising roughly 200 hair strands (similar in size to a #2 pencil) closest to the scalp, provides 100mg of hair, the perfect amount for initial screening and confirmation. For tests such as EtG, add-ons, or panels exceeding 10, 150mg of the sample is advisable. We suggest using a jeweler’s scale to weigh the specimen. In cases where scalp hair is not available, an equivalent quantity of body hair can be collected. Specifically, when mentioning head hair, it refers solely to scalp hair, while body hair includes all other types (facial, axillary, etc.).

Process Overview

The laboratory processing of drug test results spans four main steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the primary processing of a specimen into a lab’s system. This step involves ensuring the sample is sealed and shipped correctly, allocating a random LAN (Laboratory Accessioning Number), and completing any extra data entry not covered by an electronic chain of custody system.

Screening carries out an initial brief test for drugs of abuse. While Screening is an economical way to dismiss drug use in many samples, a positive finding in screening requires confirmation to be valid in court. Any specimens preliminarily positive in Screening demand subsequent confirmation.

If a specimen tests preliminarily positive in the Screening phase, additional hair is extracted from the initial sample and readied for Extraction. In this step, drugs are withdrawn from hair at a significantly reduced concentration than in other methods (e.g., urine or oral fluid), making hair drug screening particularly challenging to execute.

Confirmation of any positive screening result is conducted via GC/MS, GC/MS/MS, or LC/MS/MS. All specimens preliminarily positive are washed prior to confirmation as necessary. The full lab process from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair designation and accredited by ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Lengthy detection period: Hair drug tests detect drug use for up to 90 days, compared to urine tests with a shorter detection span.
• Hard to manipulate: It is quite challenging to alter a hair drug test, ensuring more precise outcomes.
• Supplies historical data: It offers a pattern of drug use over a duration, not just recent consumption.

Limitations:

• Incapable of detecting recent use: It requires around 5-7 days for drugs to appear in hair.
• Expense: Hair drug tests commonly cost more than other drug testing approaches.
• Result variations: Elements like hair color and individual hair growth differences can influence drug metabolite concentrations in hair.

Note: Although often mentioned as "hair follicle tests", the analysis examines the hair strand and not the follicle beneath the scalp.
