Hair Follicle Drug Testing - Sherman, KY

What it is, How it works

Hair analysis is now regarded as an effective method for detecting drug and alcohol consumption. By embedding biomarkers within the fibers of the growing hair, hair offers a prolonged historical record of drug and alcohol intake. Hair, when cut near the scalp, can reflect up to a three-month window for detecting alcohol and substance use. It is easy to gather, somewhat hard to tamper with, and straightforward to transport.

A 1.5-inch segment consisting of around 200 hair strands (roughly akin to a #2 pencil) closest to the scalp yields 100mg of hair, which is the optimal amount for initial testing and verification. For EtG, extras, or panels of over 10, a 150mg sample is advisable. Usage of a jeweler’s scale for weighing the sample is suggested. In the absence of scalp hair, a similar quantity of body hair might be used. Reference to head hair pertains solely to scalp hair, while body hair encompasses all other hair types (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test involves four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning includes the preliminary handling of a specimen into a lab's system. This process entails confirming the proper sealing and shipping of the sample, assigning an arbitrary LAN (Laboratory Accessioning Number), and completing any supplementary data entry that did not come through an electronic chain of custody system.

Screening consists of a swift preliminary test for drugs of abuse. Although Screening offers a cost-efficient method to exclude drug use in most samples, a positive screen must be corroborated for ascertaining admissibility in legal settings. Specimens that are deemed presumptive positive require a follow-up confirmation.

If a sample is suspected to be positive during Screening, additional hair is taken from the original specimen and readied for Extraction. This phase extracts drugs from hair at a lesser concentration compared to other techniques (such as urine or oral fluid), rendering hair drug testing the most challenging methodology to execute.

Every positive screening result is validated using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All presumptive positive samples undergo a wash before confirmation, when necessary. The complete lab process, from Accessioning to Confirmation, is conducted under the CAP (College of American Pathologists) Hair designation, alongside the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection window: Hair tests can identify drug usage for up to 90 days, unlike urine tests which are limited to shorter detection periods.
• Hard to deceive: Cheating a hair drug test is exceedingly difficult, hence the results are usually more reliable.
• Historical use data: It showcases a drug usage trend over time, rather than highlighting recent use alone.

Limitations:

• Cannot identify recent use: Drug detection in hair takes around 5-7 days.
• Expense: Hair testing is typically pricier than other drug testing types.
• Result variability: Variables such as hair color and personal differences in hair growth can influence drug metabolite concentrations in hair.

Note: Although often termed "hair follicle tests", the test examines the hair strand, not the follicle beneath the scalp.
