Hair Follicle Drug Testing - Merrifield, VA

What it is, How it works

Hair testing has emerged as a robust method for detecting drug and alcohol use. Hair offers a prolonged timeline of substance use by capturing biomarkers within the strands as the hair grows. When gathered near the scalp, hair can provide a detection period of up to three months for alcohol and drugs. Hair is easy to gather, relatively hard to alter, and simple to transport.

A 1.5-inch segment consisting of roughly 200 hair strands (approximately the width of a #2 pencil) near the scalp yields 100mg of hair, which is the optimal amount for screening and confirmation. For EtG, add-ons, and tests exceeding 10 panels, 150mg of hair is suggested. We advise checking the specimen’s weight on a jeweler’s scale. If scalp hair cannot be collected, a similar quantity of body hair can be obtained. With head hair, we specifically mean scalp hair. Body hair encompasses all other hair types (such as facial and axillary).

Process Overview

The four primary stages in handling a drug test in a lab are Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial phase of entering a sample into a lab's system. This includes checking that the sample was properly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and finishing any extra data entry not provided by an electronic chain of custody system.

Screening consists of a preliminary fast check for drug abuse. Although Screening is a cost-efficient approach to exclude drug use in most samples, a positive result must be confirmed to be valid in legal settings. Any samples indicating a presumptive positive in Screening need further verification.

If a sample shows a presumptive positive in the Screening stage, additional hair is taken from the initial specimen for the Extraction process. Drugs are removed from hair at notably lower concentrations than other methods (like urine or oral fluid), making hair drug screening the most complex method to execute.

Verification of any positive screening outcome occurs through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleansed before confirmation if necessary. The comprehensive lab procedure from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug examinations can identify drug use for as long as 90 days, contrasting with urine tests that have a reduced detection duration.
• Difficulty in manipulation: It is exceedingly challenging to manipulate a hair drug test, enhancing result accuracy.
• Historical data provision: It offers a pattern of drug use over time, beyond just recent use.

Limitations:

• Inability to detect recent use: Drugs require around 5-7 days to become detectable in hair.
• Expense: Hair drug tests are typically more costly than other methods.
• Result variations: Factors like hair color and individual hair growth variations can influence drug metabolite concentration in hair.

Note: Although commonly called "hair follicle tests," the examination itself analyzes the hair strand, not the follicle beneath the scalp.
