Hair Follicle Drug Testing - Melbourne, AR

What it is, How it works

Perceived as a robust method, hair testing plays a vital role in identifying drug and alcohol consumption. Hair acts as a long-term record by capturing biomarkers within the fibers of the growing strand. When cut near the scalp, hair offers a detection span of up to roughly three months for both alcohol and other drugs. It's easy to gather, somewhat resistant to tampering, and straightforward to transport.

A 1.5-inch segment containing around 200 strands of hair (similar in size to a #2 pencil) taken closest to the scalp yields 100mg, which is the preferred sample for assessment and validation. For EtG, additional tests, and/or screenings exceeding 10 panels, a 150mg sample is advised. The specimen should ideally be weighed on a jeweler’s scale. If scalp hair is not available, the same quantity of body hair may be used. By head hair, we mean only scalp hair. Body hair denotes all other types (facial, axillary, etc.).

Process Overview

There are four key steps in the laboratory processing of a drug test result: Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the initial handling of a sample into a laboratory's system. This encompasses ensuring the sample’s seal and shipment integrity, assigning a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry missing from an electronic chain of custody system.

Screening involves a preliminary check for substances of abuse. While Screening is a cost-effective means to dismiss drug use in most samples, a positive screen needs confirmation for legal admissibility. Any samples that test positive on Screening require another level of confirmation.

If a Screening indicates a presumptive positive, additional hair is taken from the original specimen for Extraction. In this phase, drugs are extracted from hair at lower concentrations than other methods (e.g., urine or oral fluid), making hair drug screening more challenging than other approaches.

Confirmed positive screening results use GC/MS, GC/MS/MS, or LC/MS/MS. All samples testing presumptively positive undergo washing before confirmation as needed. The entire laboratory procedure from Accessioning to Confirmation is reviewed under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 standards accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can detect drug consumption for up to 90 days, whereas urine tests have a shorter detection period.
• Hard to falsify: Tampering with hair drug tests is particularly challenging, enhancing result accuracy.
• Offers a historical overview: It can reveal a pattern of drug use over time, not merely recent use.

Limitations:

• Cannot reveal recent usage: It takes roughly 5-7 days for drugs to become detectable in hair.
• Expense: Hair drug tests generally incur higher costs than other testing methods.
• Outcome variability: Factors such as hair color and individual growth differences can influence metabolite concentrations in hair.

Note: Often called "hair follicle tests", the test examines the hair strand rather than the follicle beneath the scalp
