Hair Follicle Drug Testing - Holmesville, NE

What it is, How it works

Considered an effective method, hair analysis aids in detecting drug and alcohol consumption. Hair offers an extensive history of substance use by capturing markers within the fibers of the growing hair. When taken near the scalp, it can provide up to a 90-day detection span for substances. Hair is easy to gather, hard to tamper with, and straightforward to transport.

A 1.5-inch section of approximately 200 hair strands (roughly the width of a #2 pencil) closest to the head will yield 100mg of hair, the optimal sample for testing and verification. For screening like EtG, add-ons, and/or assessments exceeding 10 panels, 150mg of hair is advisable. It's recommended to measure the hair on a jeweler's scale. If no scalp hair is available, a comparable quantity of body hair may be used. When referencing head hair, we mean scalp hair only. Body hair includes all other types (facial, axillary, etc.).

Process Overview

The primary steps in laboratory processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.

Accessioning begins with the sample's initial incorporation into a lab's system. This process entitles checking that the sample was sealed and transported correctly, allocating a random LAN (Laboratory Accessioning Number), and concluding any residual data entry missing from an electronic chain of custody system.

Screening involves a preliminary rapid assessment for the presence of prohibited drugs. Though Screening is an economically efficient approach to exclude drug consumption in the majority of cases, a favorable screen must be verified for courtroom validity. All presumptively positive samples in Screening require rigorous confirmation.

If the sample indicates a positive in the Screening phase, more hair is extracted from the initial collection and prepped for Extraction. In this segment, substances are separated from hair at significantly lower concentrations than in other techniques (e.g., urine or oral fluid), which is why hair testing is among the most challenging techniques to execute.

To verify any positive screening outcome, GC/MS, GC/MS/MS, or LC/MS/MS are employed. Each presumptive positive specimen undergoes washing before confirmation, if necessary. Throughout the laboratory process from Accessioning to Confirmation, reviews are conducted under both the CAP (College of American Pathologists) Hair specification and the ISO / IEC 17025 certification standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can recognize drug intake up to 90 days, unlike urine tests that offer a shorter detection span.
• Hard to deceive: It is extremely challenging to manipulate a hair drug test, leading to more precise outcomes.
• Supplies historical insights: It reveals a pattern of drug usage over a timeframe, rather than just recent activity.

Limitations:

• Unusual for detecting recent ingestion: Drugs generally take about 5-7 days to be noticeable in hair.
• Expense: Hair drug tests are typically pricier than other drug testing techniques.
• Result variances: Elements like hair color and unique hair growth patterns can influence metabolite concentration levels in hair.

Note: Though often termed "hair follicle tests", the test focuses on analyzing the hair strand itself, not the follicle beneath the scalp.
