Hair Follicle Drug Testing - Biltmore, TN

What it is, How it works

Hair testing has emerged as a potent mechanism for spotting drug and alcohol consumption. It captures the long-term presence of alcohol and drugs by embedding biomarkers within the fibers of the developing hair strand. When gathered near the scalp, hair can deliver a detection timeline of up to roughly three months for alcohol and other drugs. Hair is easy to gather, not easily altered, and straightforward to transport.

A sample of 1.5 inches, comprising approximately 200 strands of hair (similar in size to a #2 pencil), taken from the nearest part of the scalp will amount to 100mg of hair, the perfect sample for both screening and confirmation. For advanced testing such as EtG, additional tests, and/or those exceeding 10 panels, a specimen of 150mg is advised. We suggest weighing the sample using a jeweler’s scale. If scalp hair is absent, an equivalent portion of body hair might be collected. When we discuss head hair, we specifically mean scalp hair. Body hair encompasses all other hair types (such as facial, axillary, etc.).

Process Overview

The laboratory's drug test result processing encompasses four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial stage of processing a sample within a laboratory's system. This phase includes confirming the sample's seal and shipment were done correctly, assigning a random LAN (Laboratory Accessioning Number), and finalizing any remaining data entry not covered by an electronic chain of custody system.

Screening offers an initial rapid assessment for substances of abuse. While Screening is an economical way to exclude drug usage in most samples, a positive screen necessitates verification to be countable in court. Any samples initially appearing positive in Screening require a follow-up confirmation.

If a sample is initially positive during the Screening phase, additional hair is extracted from the primary specimen and prepped for Extraction. At this stage, drugs are isolated from hair at much lower concentrations compared to other methodologies (such as urine or oral fluid), which underlines why hair drug testing is the most complex methodology to execute.

Verification of any positive screening results is achieved through GC/MS, GC/MS/MS, or LC/MS/MS. All preliminarily positive samples undergo cleansing prior to confirmation based on necessity. The complete laboratory flow from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair standards and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Sustained detection period: Hair drug assessments can recognize drug use for as long as 90 days, in contrast to urine tests which have a reduced detection window.
• High resistance to alteration: It's quite challenging to deceive a hair drug test, hence ensuring more reliable outcomes.
• Reveals historical consumption: Offers an overview of drug habits over a monitored duration, and not merely recent ingesting.

Limitations:

• Non-detection of immediate use: It requires around 5-7 days for drugs to appear in hair.
• Expense: Hair drug evaluations generally command a higher price compared to other testing techniques.
• Result variability: Deviations such as hair color and personal hair growth disparities can impact the presence of drug metabolites in the hair.

Note: Commonly termed "hair follicle tests," the examination actually focuses on the hair strand, not the follicle beneath the scalp
