Hair Follicle Drug Testing - Lithopolis, OH

What it is, How it works

Hair analysis has emerged as an effective means for identifying substance and alcohol usage. The growing hair traps biomarkers within its fibers, providing a lengthy history of alcohol and drug consumption. Collecting hair close to the scalp can lead to a detection window of nearly three months for alcohol and drugs. The collection process for hair is straightforward, hard to tamper with, and convenient to transport.

A 1.5-inch segment consisting of around 200 hair strands (similar to a #2 pencil's size) nearest to the scalp offers 100mg of hair, suitable for both screening and confirmation. For EtG, additional tests, or panels beyond 10, a 150mg sample is best. Using a jeweler’s scale is recommended to weigh the sample. If no scalp hair exists, body hair can be collected in an equivalent quantity. References to head hair pertain solely to scalp hair, while body hair includes all other hair types (facial, axillary, etc.).

Process Overview

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

Accessioning refers to the initial integration of a sample into a lab's system. This phase includes verifying appropriate sample sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data entry absent from an electronic chain of custody system.

Screening serves as an initial rapid check for drugs of abuse. While Screening provides a cost-effective method to rule out drug use in most samples, any positive result must be confirmed for court admissibility. Samples with presumptive positives in Screening necessitate secondary confirmation.

If Screening suggests a positive result, additional hair is extracted from the original specimen and readied for Extraction. During this phase, drugs are extracted from hair at considerably lower concentrations compared to other methods (e.g., urine or oral fluid), making hair drug testing one of the most challenging methodologies.

Confirming any positive Screening outcomes is achieved via GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, presumptive positive samples undergo a wash if required. The entire laboratory operation from Accessioning to Confirmation is examined under both CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests offer a 90-day drug detection window compared to the shorter period for urine tests.
• High resistance to tampering: The difficulty in cheating a hair drug test enhances result accuracy.
• Retrospective data availability: It reveals drug use trends over time rather than just recent consumption.

Limitations:

• Inability to detect recent usage: Typically, it takes about 5-7 days for drugs to become traceable in hair.
• Expense: Hair drug tests are often costlier than alternative drug testing methods.
• Result variability: Factors like hair color and individual differences in hair growth might influence drug metabolite concentration in hair.

Note: Although termed "hair follicle tests", the examination targets the hair strand instead of the follicle beneath the scalp
