Hair Follicle Drug Testing - Star, TX

What it is, How it works

Hair testing has emerged as a robust method for identifying drug and alcohol consumption. Hair captures a long-term history of drug and alcohol intake via biomarkers that get embedded in the fibers of the growing hair strand. When obtained from near the scalp, it can offer a detection span of around three months for various substances. Collecting hair is straightforward, tampering is fairly challenging, and it can be shipped effortlessly.

Gathering a 1.5-inch segment of roughly 200 hair strands (about the diameter of a #2 pencil) near the scalp will yield 100mg of hair, ideal for testing. For EtG, add-ons, and/or assessments beyond 10 panels, obtaining 150mg is advised. We suggest using a jeweler’s scale for precise measurement. In the absence of scalp hair, an equivalent volume of body hair can be taken. When mentioning head hair, we refer solely to scalp hair. Body hair encompasses all other types like facial, axillary, etc.

Process Overview

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

Accessioning includes integrating the sample into a laboratory’s system. This involves ensuring that the sample was sealed and dispatched correctly, issuing a random LAN (Laboratory Accessioning Number), and completing any missing data not submitted by an electronic custody system.

Screening involves a preliminary evaluation for drug presence. It’s a cost-efficient method to eliminate drug usage in most samples, but a positive result needs a follow-up confirmation for legal acceptability. Samples with initial positive results in Screening require a secondary confirmation.

Should a sample test positive during Screening, additional hair is extracted from the original sample and prepared for Extraction. Here, drugs are separated from the hair at lower concentrations compared to other techniques (e.g., urine or oral fluid), making hair screening notably challenging.

For any positive Screen, Confirmation is done using GC/MS, GC/MS/MS, or LC/MS/MS. Any samples that test positive are cleansed before confirmation as necessary. The entire lab process, from Accessioning to Confirmation, is reviewed under the CAP (College of American Pathologists) Hair classification and aligned with ISO / IEC 17025 credentials.

Advantages of hair drug testing:

• Extended detection timeframe: Hair drug screenings can reveal drug use for up to 90 days, contrasting with urine tests, which have a shorter detection span.
• Hard to falsify: It is very difficult to manipulate a hair drug test, enhancing result accuracy.
• Supplies archival data: It can depict a pattern of substance use over time, rather than capturing only recent use.

Limitations:

• Incapable of identifying recent use: Drugs become detectable in hair roughly 5-7 days post-consumption.
• Expense: Hair drug assessments usually cost more than other testing methods.
• Result variations: Factors such as hair color and personal differences in hair growth can influence drug metabolite concentration in hair.

Note: Though frequently referred to as "hair follicle tests", the actual test analyzes the hair strand, not the scalp follicle.
