Hair Follicle Drug Testing - Robe, WA

What it is, How it works

Hair testing is now regarded as an effective instrument for identifying drug and alcohol consumption. Hair offers a prolonged history of alcohol and drugs by capturing biomarkers within the fibers of the hair strand as it grows. When taken near the scalp, it can reveal substance use over a span of roughly three months. The collection process for hair is straightforward, challenging to tamper with, and simple to transport.

A sample of 1.5 inches of hair, around 200 strands (comparable to a #2 pencil in thickness) closest to the scalp, weighs approximately 100mg, which is the ideal amount for screening and confirmation. For EtG, add-ons, and/or tests exceeding 10 panels, a quantity of 150mg is suggested. It's advisable to weigh the sample using a jeweler’s scale. In the absence of scalp hair, a similar quantity of body hair can be gathered. References to head hair pertain solely to scalp hair. Body hair encompasses all other types of hair (such as facial, axillary, etc.).

Process Overview

The drug test result procedure in a lab consists of four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the initial introduction of a sample into the laboratory’s system. This phase verifies the sample's sealing and shipping integrity, assigns a random LAN (Laboratory Accessioning Number), and completes any supplementary data entry absent from an electronic chain of custody system.

Screening involves a preliminary examination for drugs of abuse. While this stage is a cost-efficient approach to exclude drug use in most samples, positive results must be confirmed for legal acceptability in court. Samples with presumptively positive results during Screening necessitate a secondary confirmation.

For samples deemed presumptively positive in Screening, additional hair is extracted from the primary specimen for the Extraction phase. Here, drugs are extracted from hair at much lower concentrations than other methodologies (such as urine or oral fluid), highlighting the complexity of hair drug screening.

Confirmation of a positive screening result is carried out using GC/MS, GC/MS/MS or LC/MS/MS. Presumptive positive samples undergo a wash before confirmation if necessary. The full laboratory process, from Accessioning to Confirmation, adheres to both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for up to 90 days, a longer duration compared to urine tests.
• Hard to manipulate: Cheating a hair drug test is extremely challenging, ensuring greater accuracy of the findings.
• Shows historical usage: It showcases a timeline of drug use, rather than just recent usage.

Limitations:

• No immediate usage detection: Drugs need roughly 5-7 days to become detectable in hair.
• Expense: Generally, hair drug tests are pricier than other testing methods.
• Result variability: Elements like hair color and growth differences can impact the concentration of drug metabolites in hair.

Note: Commonly called "hair follicle tests", they actually assess the hair strand, not the scalp's hair follicle.
