Hair Follicle Drug Testing - Contact, NV

What it is, How it works

Hair testing is recognized as an effective method for identifying drug and alcohol consumption. Hair offers an extended timeline of alcohol and drug use by embedding biomarkers within the hair strand as it grows. When sampled near the scalp, hair can reveal drug and alcohol intake over a span of up to three months. Hair is straightforward to collect, relatively resistant to tampering, and easy to transport.

A sample of 1.5 inches in length comprised of approximately 200 hair strands (about the thickness of a #2 pencil) closest to the scalp yields 100mg, the preferred amount for testing and confirmation. For EtG, additional panels, or tests exceeding 10 panels, 150mg of hair is advised. It's beneficial to use a jeweler’s scale for measuring the specimen. If scalp hair isn't present, the equivalent quantity of body hair can be used. When we mention head hair, it pertains solely to scalp hair. Body hair encompasses all other varieties (e.g., facial, axillary).

Process Overview

The key stages in processing a drug test at the lab include Accessioning, Screening, Extraction, and Confirmation.

Accessioning refers to the sample's initial integration into a lab's system. This involves ensuring the sample is sealed and sent correctly, assigning a random LAN (Laboratory Accessioning Number), and executing any necessary data entry absent from an electronic chain of custody system.

Screening is a preliminary examination for drugs of abuse. Though cost-effective for excluding drug use in most samples, a positive screen requires confirmation for legal acceptability. Samples with presumed positive screens necessitate further confirmation.

Should a sample test presumptively positive during Screening, additional hair is extracted from the original sample and readied for Extraction. In this phase, drugs are extracted from hair at concentrations significantly lower than in other methods (e.g., urine or oral fluid), highlighting the complexity of hair drug screening.

Confirmation of a positive screening result uses GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing before confirmation as necessary. The comprehensive lab process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can recognize drug use for up to 90 days, in contrast to urine tests with a briefer detection period.
• Hard to manipulate: Cheating on a hair drug test is significantly difficult, thus enhancing result accuracy.
• Historical insight: It offers a usage pattern over time rather than just capturing recent use.

Limitations:

• Incapable of identifying recent drug use: Drugs take about 5-7 days to become traceable in hair.
• Expense: Hair drug tests often come at a higher cost compared to other methods.
• Result variations: Variables like hair color and individual hair growth differences can influence drug metabolite concentration in hair.

Note: Commonly called "hair follicle tests", these tests examine the hair strand and not the follicle under the scalp
