Hair Follicle Drug Testing - East Missoula, MT

What it is, How it works

Hair analysis is now recognized as a powerful means for detecting drug and alcohol consumption. This method offers a long-term record of substance use by embedding biomarkers within the fibers of the growing hair strand. When obtained near the scalp, hair can provide a detection timeframe of up to approximately 90 days for alcohol and various drugs. Collecting hair samples is straightforward, moderately challenging to tamper with, and simple to transport.

A 1.5-inch segment consisting of around 200 hair strands (akin to the size of a number 2 pencil) closest to the scalp yields 100mg of hair, which serves as the ideal quantity for both screening and confirmation. For EtG, additional tests, or screenings exceeding 10 panels, it is advised to use 150mg of the sample. We suggest using a jeweler’s scale for specimen weighing. If scalp hair is unavailable, a similar quantity of body hair can be gathered. When we mention head hair, we specifically refer to scalp hair. Body hair encompasses all other types, such as facial or axillary hair.

Process Overview

The laboratory handling of a drug test result involves four core steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial integration of a sample into a lab's workflow. This process includes ensuring the sample was properly sealed and transported, assigning a random LAN (Laboratory Accessioning Number), and completing any outstanding data entry missing from an electronic chain of custody system.

Screening involves an expedited preliminary check for drug abuse. While Screening is a cost-effective method to rule out drug usage in most samples, a positive screen must be confirmed for courtroom admissibility. Samples that test presumptively positive during Screening require further confirmation.

If a sample shows a presumptive positive in the Screening phase, additional hair is extracted from the original specimen and prepared for Extraction. In this phase, substances are retrieved from hair at significantly lower concentrations than other methods (e.g., urine or oral fluid), highlighting the complexity of hair drug screening.

Confirmation of any positive Screening result is carried out using GC/MS, GC/MS/MS, or LC/MS/MS technologies. All samples presumed positive are cleansed before confirmation as necessary. The entire lab process, from Accessioning to Confirmation, undergoes review under both the CAP (College of American Pathologists) Hair categorization and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extensive detection period: Hair drug tests can identify drug use for up to 90 days, as opposed to urine tests, which have a briefer detection period.
• Hard to deceive: It is notably challenging to circumvent a hair drug test, resulting in more precise outcomes.
• Tracks historical patterns: It offers a timeline of drug usage over an extended period, not merely recent consumption.

Limitations:

• Inability to detect recent consumption: It takes approximately 5-7 days for drugs to manifest in hair.
• Expense: Hair drug tests are typically more costly than alternative drug testing methods.
• Result variability: Elements like hair color and individual hair growth rate can influence the concentration of drug metabolites in hair.

Note: Although frequently called "hair follicle tests", the examination actually evaluates the hair strand rather than the follicle embedded in the scalp

Why Hair Follicle Testing Beats Urine Testing
