Hair Follicle Drug Testing - Lancaster, OH

What it is, How it works

The analysis of hair has emerged as an effective method for detecting the consumption of drugs and alcohol. Hair strands can chronicle extended-term usage of these substances by embedding biomarkers within the fibers during hair growth. When hair is collected from a position near the scalp, it can offer a maximum detection window of approximately three months for alcohol consumption and drug use. Hair collection is straightforward, relatively tamper-resistant, and convenient for transport.

A hair specimen measuring 1.5 inches with around 200 strands (akin to the diameter of a #2 pencil) nearest to the scalp yields a 100mg sample, which is optimal for both screening and confirmation processes. For EtG, supplementary tests, and/or analyses exceeding 10 panels, the recommended sample weight is 150mg. It's suggested to use a jeweler’s scale for weighing the specimen. Should scalp hair be unavailable, a comparable quantity of body hair can be utilized. Note that references to head hair are specific to scalp hair only, while body hair encompasses all other types (facial, axillary, etc.).

Process Overview

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

Accessioning entails the intake processing of a sample within a laboratory system. This step involves confirming that the sample was sealed and shipped correctly, the assignment of a random LAN (Laboratory Accessioning Number), and completing any supplementary data input absent from an electronic chain of custody system.

Screening offers an initial rapid evaluation for drugs of abuse. Although Screening is a cost-effective method to exclude drug use for the majority of samples, a positive screening result necessitates confirmation to be deemed admissible in court. Any samples that yield presumptive positive results during Screening require subsequent confirmation.

Upon presumption of drug presence during Screening, additional hair is extracted from the initial specimen and prepared for the Extraction phase. This stage involves extracting drugs from hair, focusing on a significantly lower concentration compared to other methods (e.g., urine or oral fluid), rendering hair drug screening the most challenging methodology to implement.

The Confirmation of any positive result during screening is carried out through GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positive results are subjected to washing prior to confirmation as necessary. The entire laboratory procedure from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Pros of hair drug testing:

• Extended detection period: Hair drug assessments can ascertain drug consumption for up to 90 days, unlike urine analyses, which present a more limited detection period.
• Challenge to manipulate: Hair drug tests are notably resistant to falsification, thus the outcomes are highly reliable.
• Historical usage insight: These tests can reveal a usage pattern spanning a specific timeframe, not merely recent consumption.

Drawbacks:

• Incapable of detecting immediate usage: Drugs become detectable in hair after roughly 5-7 days.
• Expense: Hair drug analyses usually entail higher costs than alternative drug testing techniques.
• Result variability: Elements like hair color and individual differences in hair proliferation can influence the concentration of drug metabolites in hair.

Note: Despite being commonly termed "hair follicle tests", the assessment actually evaluates the hair strand, not the hair follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing
