Hair Follicle Drug Testing - Dieterich, IL

What it is, How it works

The utilization of hair analysis has increasingly become recognized as an effective means for identifying consumption of drugs and alcohol. Hair holds a prolonged historical record of substances like alcohol and drugs by encapsulating biomarkers within its fiber matrix as it grows. When gathered close to the scalp, hair can reveal substance use history for up to about a three-month period for alcohol and drugs. Collection of hair is straightforward, hard to tamper with, and convenient to transport.

A hair sample measuring 1.5 inches and comprising approximately 200 strands (approximately the thickness of a #2 pencil) when collected close to the scalp will yield 100mg of hair, which is the optimal sample size for both screening and confirmation procedures. For extensive tests, such as EtG or panels beyond 10, a 150mg specimen is advisable. It is suggested to measure the specimen weight using a jeweler’s scale. If scalp hair is absent, an equivalent portion of body hair may be used. "Head hair" strictly refers to scalp hair, while "body hair" pertains to other types (such as facial or axillary hair).

Process Overview

The core stages in the laboratory analysis of drug test results include Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the preliminary phase of processing a sample into a lab’s system. This process entails ensuring the sample’s seal and shipment integrity, allocating a random LAN (Laboratory Accessioning Number), and completing any additional data entry not covered by an electronic chain of custody process.

Screening conducts an initial rapid assessment for the presence of drugs. While Screening offers a budget-friendly approach to dismiss drug consumption in the majority of samples, a screen showing positive needs verification to be considered valid in legal contexts. Samples with presumptive positivity at the Screening stage require further confirmation.

For samples testing positive at Screening, additional hair from the initial sample is gathered for Extraction. In this phase, drugs are isolated from hair in significantly lesser concentrations than other methods (like urine or saliva), highlighting why hair drug screening is notably challenging to execute.

Verification of all positive screening outcomes is performed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Presumptively positive samples are cleansed before confirmation if necessary. Each step from Accessioning to Confirmation undergoes scrutiny in line with both the CAP (College of American Pathologists) Hair designation and accreditation per ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug assessments can identify drug use for up to 90 days, unlike urine exams which have a narrower detection range.
• Difficult to manipulate: Hair drug tests are notably hard to deceive, resulting in more precise outcomes.
• Offers usage timeline: It can illustrate a trajectory of drug use over time, as opposed to only recent consumption.

Limitations:

• Incapable of identifying recent usage: It takes roughly 5-7 days for drugs to become traceable in hair.
• Expense: Hair drug evaluations generally cost more compared to other testing methodologies.
• Result variability: Elements like hair color and individual hair growth differences can influence drug metabolite concentration in hair.

Note: Although frequently referred to as "hair follicle tests," the analysis focuses on the hair strand itself and not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Why Hair Follicle Testing Beats Urine Testing in Dieterich, IL
