Hair Follicle Drug Testing - Polacca, AZ

What it is, How it works

Hair analysis is now recognized as an effective method for identifying drug and alcohol usage. Hair strands capture biomarkers within their fibers as they grow, offering a long-term record of substance use. Collected near the scalp, hair can reveal up to a three-month history of alcohol and drug exposure. The process of collecting hair is straightforward, relatively resistant to tampering, and easy to transport.

A hair sample of 1.5 inches, consisting of around 200 strands (roughly the size of a #2 pencil) closest to the scalp, equates to 100mg of hair, which is ideal for screening and confirmatory purposes. For EtG, add-ons, and tests exceeding 10 panels, a sample of 150mg is advised. It's suggested to measure the sample using a jeweler’s scale. If scalp hair isn’t available, an equivalent amount of body hair can be used. 'Head hair' refers specifically to scalp hair, whereas 'body hair' includes all other hair types (facial, axillary, etc.).

Process Overview

The fundamental processes in lab analysis of a drug test result are Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the phase where a sample is first entered into the lab’s system. It involves verifying the sample’s seal and shipping condition, assigning a unique LAN (Laboratory Accessioning Number), and filling in any missing information not provided by an electronic chain of custody system.

Screening is performed for an initial rapid assessment of drug presence. Although cost-effective for excluding drug usage in most samples, a positive screen must be confirmed for legal defensibility. Samples showing presumptive positive results in Screening require confirmation.

In the event of a presumptive positive result during Screening, additional hair is extracted from the original sample and prepared for the Extraction phase. At this point, drugs are extracted at lower concentrations than with other methods (such as urine or oral fluid), which makes hair drug screening the most challenging technique to execute.

Confirmation of any positive screen is achieved using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Presumptive positive samples are washed as needed before confirmation. The lab process, from Accessioning to Confirmation, undergoes review under both CAP (College of American Pathologists) Hair standards and accreditation following ISO / IEC 17025 guidelines.

Advantages of hair drug testing:

• Extended detection window: Hair tests can reveal drug usage history up to 90 days, whereas urine tests offer a shorter detection timeframe.
• Hard to manipulate: It’s extremely challenging to alter the outcome of a hair drug test, leading to more reliable results.
• Shows usage trends: This test can display patterns of usage over time, rather than just recent consumption.

Limitations:

• Inability to detect recent usage: Detection in hair takes roughly 5-7 days post-consumption.
• Higher cost: Hair drug testing is usually more expensive compared to other testing methods.
• Result variability: Elements like hair color and individual hair growth differences can influence drug metabolite concentrations in hair.

Note: Commonly called "hair follicle tests," the analysis focuses on the hair strand itself, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing
