Hair Follicle Drug Testing - Elroy, NC

What it is, How it works

Hair analysis has become recognized as an effective method for detecting drug and alcohol consumption. Hair offers an extended history of substance use by embedding biomarkers within the fiber of the hair as it grows. When taken near the scalp, hair can furnish up to about a 3-month timeframe for detecting alcohol and drugs. Hair is easy to gather, moderately challenging to tamper with, and straightforward to transport.

A 1.5-inch segment made up of roughly 200 hair strands (akin to the thickness of a #2 pencil) nearest the scalp will yield 100mg of hair, which is the preferred sample amount for analysis and verification. For testing including EtG, add-ons, and/or more than 10 panels, 150mg of the sample is suggested. Utilizing a jeweler’s scale to weigh the specimen is advised. If scalp hair cannot be sourced, a comparable quantity of body hair might be utilized. When mentioning head hair, it refers specifically to scalp hair. Body hair encompasses all other hair varieties (including facial, axillary, etc.).

Process Overview

The four foundational stages of processing a drug test outcome in the laboratory are Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial handling of a sample into a laboratory's framework. Steps involve affirming that the sample was correctly sealed and sent, allocating a random LAN (Laboratory Accessioning Number), and completing any further data input not covered by an electronic chain of custody system.

Screening consists of a preliminary rapid assessment for substances of abuse. Although Screening is economically efficient for eliminating drug usage in most samples, confirmatory tests are required for a positive screen to stand in court. Any samples flagged as presumptively positive in Screening necessitate further confirmation.

Should a sample test presumptively positive during Screening, additional hair is extracted from the initial sample and readied for Extraction. In this phase, drugs are extracted from hair at much lower concentrations than other techniques (e.g., urine or oral fluids), which is why hair drug screening is considered challenging to carry out.

Verification of any positive preliminary result is accomplished through GC/MS, GC/MS/MS, or LC/MS/MS methods. All presumptive positive specimens undergo cleansing predating confirmation where necessary. The entire processing sequence from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair certification and the ISO / IEC 17025 accreditation standards.

Benefits of hair drug analysis:

• Extended detection period: Hair testing can reveal drug use for as long as 90 days, unlike urine testing that has a shorter detection span.
• Low likelihood of cheating: It is quite challenging to tamper with a hair drug test, rendering the results more reliable.
• Historical insight: It can provide a timeline of drug usage over an extended period, unlike focusing solely on recent use.

Drawbacks:

• Inability to spot recent use: It takes approximately 5-7 days for drugs to become detectable within the hair.
• Expense: Hair drug assessments tend to be more costly than other drug testing approaches.
• Result variations: Aspects such as hair color and personal hair growth variations can impact drug metabolite levels in the hair.

Note: Often known as "hair follicle tests," this test actually examines the hair strand and does not include the hair follicle beneath the scalp.
