Hair Follicle Drug Testing - Almena, WI

What it is, How it works

The analysis of hair has become recognized as an effective method for identifying drug and alcohol consumption. Hair retains a record of alcohol and drugs over time by embedding biomarkers within the fibers of the hair as it grows. Hair collected near the scalp can detect alcohol and drugs for a period of up to around 3 months. It is easy to gather, fairly resistant to tampering, and straightforward to transport.

A sample measuring 1.5 inches, comprising about 200 strands of hair (roughly the thickness of a #2 pencil) closest to the scalp, yields 100mg of hair, which is ideal for both screening and confirmation. For EtG, additional tests, and/or panels exceeding 10, a specimen weighing 150mg is advisable. We advise using a jeweler’s scale for weighing the specimen. If scalp hair isn't accessible, a similar quantity of body hair may be used. When mentioning head hair, we refer solely to scalp hair, while body hair includes all other types (such as facial and axillary hair).

Process Overview

The core steps in processing a drug test result in a lab are Accessioning, Screening, Extraction, and Confirmation.

Accessioning refers to the initial process of incorporating a sample into a laboratory system. This step includes checking the sample's shipment and seal, assigning a unique LAN (Laboratory Accessioning Number), and completing additional data entry that might not be provided by an electronic chain of custody system.

Screening is a preliminary, rapid assessment for drugs of abuse. While it efficiently eliminates drug usage for most samples, a positive result from Screening must be validated for courtroom acceptance. Any presumptive positives in Screening require a follow-up confirmation.

At the Screening stage, if a sample tests presumptively positive, additional hair is extracted from the initial sample and prepared for the Extraction phase. Drugs are extracted from hair at a much lower concentration than with other methods (e.g., urine or oral fluid), making hair drug tests more challenging.

Confirmation of positive screening results is performed using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptively positive samples undergo a cleansing process before confirmation if necessary. The entire procedure from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 standards accreditation.

Advantages of hair drug testing:

• Extended detection timeframe: Hair drug tests can reveal drug use for up to 90 days, unlike urine tests which have a shorter detection period.
• Hard to undermine: Hair drug tests are difficult to cheat, resulting in more precise outcomes.
• Displays historical usage: It can illustrate a pattern of drug usage over time, rather than just recent consumption.

Limitations:

• Inability to detect recent use: Drugs take about 5-7 days to become detectable in hair.
• Expense: Hair drug tests generally incur higher costs than alternative testing methods.
• Outcome variations: Factors such as hair color and individual differences in hair growth can influence the concentration of drug metabolites in hair.

Note: Though commonly called "hair follicle tests", the test actually examines the hair strand and not the hair follicle beneath the scalp.
