Hair Follicle Drug Testing - Willow, WI

What it is, How it works

Hair analysis is now recognized as a significant method for identifying drug and alcohol consumption. Hair strands capture biomarkers in their fibers during growth, presenting a comprehensive history of substance use. When collected near the scalp, it can deliver an alcohol and drug detection window of up to about three months. The hair collection is straightforward, difficult to tamper with, and convenient to transport.

A sample size of 1.5 inches, consisting of roughly 200 hair strands (comparable to the girth of a #2 pencil), yields about 100mg of hair, which is ideal for both initial and confirmatory tests. For EtG, additional tests, or panels exceeding 10, a 150mg sample is advised. Utilizing a jeweler's scale for weighing the sample is recommended. If scalp hair isn't available, body hair in equivalent quantity can be used. References to head hair imply only scalp hair. Body hair encompasses all other types including facial and axillary hair.

Process Overview

The key phases of laboratory processing for a drug test outcome involve Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the preliminary phase of integrating a sample into a lab's system. This step confirms the proper sealing and shipping of the sample, assigns a LAN (Laboratory Accessioning Number) randomly, and completes any extra data not covered by an electronic chain of custody.

Screening conducts an initial brisk evaluation for drug substances. Although Screening is an economical approach to dismiss drug usage in most samples, any positive result requires confirmation for court acceptance. Presumptively positive samples found in Screening must undergo a further confirmation.

In cases where a sample shows presumptive positivity during Screening, extra hair is extracted from the initial sample and set for Extraction. During this stage, drugs are withdrawn from the hair at significantly lower concentrations than noted in other methods (e.g., urine or oral fluid), highlighting the complexity of hair drug screening.

Confirmation of any positive screen is executed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Each sample indicating presumptive positivity is cleansed before confirmation as required. The complete laboratory process, from Accessioning to Confirmation, is evaluated under the CAP (College of American Pathologists) Hair classification and the ISO / IEC 17025 standards accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can uncover drug use for up to 90 days, unlike urine tests which offer a shortened detection period.
• Challenging to evade: The integrity of a hair drug test is high, making manipulation of outcomes more difficult.
• Historical insight: It offers a pattern of drug use over a timeframe, instead of merely recent usage.

Limitations:

• Incapable of recent detection: Approximately 5-7 days are needed for drugs to manifest in hair.
• Expense: Hair drug tests typically incur higher costs than alternative testing methods.
• Result variability: Factors such as hair pigmentation and individual hair growth rate can influence drug metabolite concentrations.

Note: Despite being commonly labeled as "hair follicle tests," the analysis targets the hair strand rather than the follicle beneath the scalp.
