Hair Follicle Drug Testing - Alliance, NE

What it is, How it works

Hair analysis has emerged as an effective method for identifying drug and alcohol consumption. It provides a comprehensive timeline of substance use by encapsulating biomarkers within the fibers as the hair grows. Hair samples collected near the scalp can reveal drug and alcohol use within an approximately three-month span. The collection process is straightforward, difficult to tamper with, and convenient for shipping.

A 1.5-inch segment consisting of roughly 200 hair strands (comparable to the width of a #2 pencil) from the scalp yields 100mg of hair, which is an optimal quantity for both screening and confirmation. A specimen quantity of 150mg is advised for EtG, add-ons, or test panels exceeding 10. Using a jeweler’s scale to weigh the sample is suggested. If scalp hair is not available, a comparable quantity of body hair can be used. The term head hair is specifically referring to scalp hair only, while body hair encompasses all other hair types (such as facial or axillary hair).

Process Overview

The drug testing procedure in the lab involves four key stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning refers to the initial integration of a sample into the lab's workflow. This step involves ensuring that the sample is properly sealed and transported, assigning a random LAN (Laboratory Accessioning Number), and completing any supplementary data not covered by an electronic chain of custody.

Screening serves as a preliminary assessment for drug presence. It offers a cost-effective method to rule out drug usage in most samples, though positive results require confirmation for legal purposes. Any samples that yield a presumptive positive during Screening must undergo further validation.

In cases of a presumptively positive sample during the Screening phase, additional hair is obtained from the initial sample for the Extraction process. In this stage, drugs are extracted from hair at concentrations lower than those in other test types (such as urine or oral fluid), which is why hair drug testing is among the more complex methodologies.

Confirmation of positive screening findings is carried out via GC/MS, GC/MS/MS, or LC/MS/MS techniques. Presumptive positive samples are cleansed before undergoing confirmation if necessary. The entire procedural sequence from Accessioning to Confirmation is evaluated in line with both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection range: Hair drug testing can reveal drug usage up to 90 days, unlike urine tests with shorter detection periods.
• Hard to falsify: Cheating a hair drug test is highly challenging, offering more reliable results.
• Chronological data: It demonstrates a pattern of drug consumption over time, rather than solely recent use.

Limitations:

• Inability to identify recent usage: Detection of drugs in hair takes approximately 5-7 days after use.
• Expense: Hair drug tests are typically costlier compared to other testing methods.
• Result variations: Factors like hair color and individualized hair growth rates can influence the level of drug metabolites found in hair.

Note: Despite being commonly called "hair follicle tests", the analysis targets the hair strand, not the follicle beneath the scalp.
