Hair Follicle Drug Testing - Deloit, IA

What it is, How it works

Hair testing is widely recognized as an effective method for identifying drug and alcohol consumption. Hair retains a comprehensive record of alcohol and other substances by capturing biomarkers within the growing hair's fibers. When gathered near the scalp, hair can offer an estimated detection window of up to 3 months for alcohol and drugs. Hair is straightforward to collect, challenging to tamper with, and convenient for shipping.

A 1.5-inch segment of roughly 200 hair strands (comparable to the size of a #2 pencil) nearest the scalp yields 100mg of hair, the optimal sample size for screening and confirmation. For EtG, add-ons, and/or tests exceeding 10 panels, a 150mg sample is advisable. Using a jeweler’s scale, the specimen should be weighed. If scalp hair is not available, a similar quantity of body hair can be collected. When mentioning head hair, we mean scalp hair exclusively. Body hair covers all other hair types (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result involves four key steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning encompasses the initial integration of a sample into a laboratory's system. This step involves confirming proper sealing and shipping of the sample, allocating a random LAN (Laboratory Accessioning Number), and completing additional data entry not covered by an electronic chain of custody.

Screening is a preliminary rapid assessment for drugs of abuse. While Screening is a cost-efficient method to exclude drug usage for most samples, a positive screen must be verified for court admissibility. Presumptively positive Screening results necessitate a secondary confirmation.

Presumptively positive samples in the Screening phase require more hair to be extracted from the initial specimen for further processing. During Extraction, drugs are isolated from hair at significantly lower concentrations than seen in other methods (e.g., urine or oral fluid), highlighting why hair drug screening is considered the most intricate methodology.

Positive screening results undergo Confirmation using GC/MS, GC/MS/MS, or LC/MS/MS. Prior to Confirmation, necessary washing of presumptive positive samples occurs. The complete laboratory process from Accessioning to Confirmation adheres to both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extensive detection window: Hair drug tests can reveal drug use over a 90-day period, unlike urine tests with shorter detection durations.
• Hard to manipulate: Cheating a hair drug test is highly challenging, enhancing result accuracy.
• Offers historical insight: It depicts a usage pattern over time, beyond recent use alone.

Limitations:

• Cannot identify recent use: Drugs become detectable in hair approximately 5-7 days post-consumption.
• Expense: Hair drug tests typically cost more than alternative testing methods.
• Result variability: Differing factors, such as hair color and personal growth rates, can influence drug metabolite levels in hair.

Note: While commonly termed "hair follicle tests", the procedure analyzes the hair strand and not the follicle beneath the scalp
