Hair Follicle Drug Testing - Woodlawn, NC

What it is, How it works

Hair analysis has emerged as an effective method for identifying drug and alcohol consumption. By embedding biomarkers within the fibers of a growing hair strand, hair offers a prolonged history of substance use. A sample collected near the scalp can provide an alcohol and other drug detection period of up to around three months. Hair is easy to gather, difficult to tamper with, and straightforward to transport.

A 1.5-inch section consisting of about 200 hairs (around the diameter of a #2 pencil) closest to the scalp yields 100mg, which is the preferred sample size for testing. For EtG, additional tests, or panels exceeding 10, a specimen weight of 150mg is suggested. We advise using a jeweler's scale to weigh the specimen. If scalp hair isn't available, an equivalent portion of body hair may be utilized. The term head hair exclusively refers to scalp hair. Body hair includes all other types (face, armpit, etc.).

Process Overview

The four primary phases in the lab processing of a drug test result consist of Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the initial handling of a sample within a lab's framework. This step includes confirming proper sealing and shipment of the sample, assigning a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry absent in an electronic chain of custody system.

Screening involves a preliminary fast check for drug abuse. While screening economically excludes drug usage in most samples, any positive result must be verified for court acceptance. Presumed positive samples in Screening require secondary validation.

If a sample shows a presumptive positive result in Screening, additional hair is used from the original specimen for Extraction. In this phase, drugs are extracted from hair at significantly lower concentrations compared to other methods such as urine or oral fluid, which makes hair drug screening the most complex methodology to execute.

Positive screening outcomes are confirmed using GC/MS, GC/MS/MS or LC/MS/MS. All presumptive positive samples undergo washing prior to confirmation if required. The comprehensive lab process, from Accessioning to Confirmation, undergoes evaluation under both CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests can identify drug usage for up to 90 days, unlike urine tests, which have a relatively shorter detection window.
• Low likelihood of manipulation: The difficulty in evading a hair drug test leads to more precise results.
• Tracks usage history: It can present a record of drug usage over time, rather than just current consumption.

Limitations:

• Inability to detect recent usage: Drugs require approximately 5-7 days to become detectable in hair.
• Expense: Hair drug tests typically cost more than other testing methods.
• Result variability: Hair color and individual growth variations can influence the concentration of drug metabolites within the hair.

Note: Though commonly labeled as "hair follicle tests", the evaluation targets the hair strand, not the follicle beneath the scalp.
