Hair Follicle Drug Testing - Sheppard, AR

What it is, How it works

Hair analysis is now recognized as an effective resource for identifying drug and alcohol consumption. Hair offers a comprehensive timeline of alcohol and substance intake by embedding biomarkers within the strands of growing hair. When gathered close to the scalp, hair samples can present an approximate 3-month window for detecting alcohol and other substances. Hair collection is straightforward, not easily tampered with, and convenient for shipping.

A sample measuring 1.5 inches, containing around 200 strands (roughly the size of a #2 pencil) from the scalp, will produce 100mg of hair, which is the ideal amount for both initial testing and follow-up confirmation. For EtG, additional tests, and/or tests exceeding 10 panels, a 150mg sample is advised. Using a jeweler’s scale for weighing the sample is recommended. In cases where scalp hair cannot be obtained, a similar quantity of body hair can be utilized. When mentioning head hair, we refer exclusively to scalp hair. Body hair encompasses all other types of hair (facial, axillary, etc.).

Process Overview

The primary steps in the lab processing of drug tests include Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial entry of a sample into the lab’s system. This phase includes ensuring the sample was sealed and transported correctly, assigning a LAN (Laboratory Accessioning Number) randomly, and completing any data entry omitted by an electronic chain of custody system.

Screening entails a preliminary examination for substances of abuse. Although Screening is an economical method to exclude drug use in most samples, a positive result must be validated to stand in legal settings. All samples showing a presumptive positive in Screening need a secondary confirmation.

If a sample exhibits a presumptive positive during Screening, additional hair is extracted from the original sample and processed for Extraction. In this phase, drugs are removed from hair at far lower levels than in other methods (such as urine or oral fluid), which accounts for the complexity of hair drug analysis.

Any positive outcome from Screening is validated through GC/MS, GC/MS/MS or LC/MS/MS. All presumptive positive samples undergo cleaning before confirmation as necessary. The entire lab process from Accessioning to Confirmation is overseen under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests can reveal drug use up to 90 days, unlike urine tests that have a shorter detection period.
• Hard to evade: Cheating a hair drug test is quite challenging, enhancing result accuracy.
• Shows historical usage: It displays drug use over time, not just recent activity.

Limitations:

• Cannot identify recent use: Drugs become detectable in hair after about 5-7 days.
• Expense: Hair drug tests typically cost more than other testing methods.
• Result variability: Elements such as hair color and individual hair growth differences may influence the concentration of drug metabolites in hair.

Note: Though often termed as "hair follicle tests", the analysis is conducted on the hair strand and not the hair follicle beneath the scalp.
