Hair Follicle Drug Testing - Libertyville, MO

What it is, How it works

Hair testing is now recognized as a formidable method for identifying drug and alcohol consumption. Hair retains a comprehensive timeline for alcohol and other drugs by embedding biomarkers within the fibers of the growing hair strand. When extracted near the scalp, hair can reveal a detection period of up to roughly 3 months for alcohol and other substances. Hair is effortless to gather, challenging to tamper with, and straightforward to transport.

A 1.5-inch segment containing around 200 hair strands (approximately the diameter of a #2 pencil) nearest to the scalp offers 100mg of hair, which is ideal for screening and confirmation purposes. For EtG, additional tests, and/or test panels exceeding 10, 150mg of the sample is suggested. It's advisable to weigh the sample on a jeweler’s scale. If scalp hair is not accessible, an equivalent quantity of body hair can be collected. 'Head hair' specifically means scalp hair. All other types (facial, axillary, etc.) are considered as 'body hair'.

Process Overview

The four main stages in the laboratory examination of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.

Accessioning encompasses the initial incorporation of a sample into a lab’s system. This process ensures the sample was sealed and sent correctly, assigns a random LAN (Laboratory Accessioning Number), and completes any additional data entry missed by an electronic chain of custody system.

Screening performs an initial rapid test for drug abuse. While being a cost-efficient means to negate drug usage in most samples, a positive screening result should be confirmed for court acceptance. Any samples with a presumptive positive in Screening require a secondary confirmation.

If a screening yields a presumptive positive, extra hair is extracted from the original sample and prepared for Extraction. During this phase, drugs are extracted from hair at notably reduced concentrations compared to other methods (e.g., urine or oral fluid), underscoring why hair drug screening is an intricate methodology to perfect.

Confirmation of any positive screening outcome is accomplished using GC/MS, GC/MS/MS, or LC/MS/MS. Any presumptive positive samples undergo washing before confirmation if needed. The complete process from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair designation and is compliant with ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests are able to identify drug use for up to 90 days, unlike urine tests which have a shorter detection period.
• Hard to manipulate: Tampering with a hair drug test is significantly challenging, thus enhancing result precision.
• Details past patterns: It reflects a historical pattern of drug use over time, not merely recent use.

Limitations:

• Inability to detect recent use: Drugs take around 5-7 days to become detectable in hair.
• Expense: Hair drug tests generally cost more compared to other drug testing techniques.
• Result discrepancies: Attributes like hair color and personal differences in hair growth can influence drug metabolite levels in hair.

Note: Though commonly called "hair follicle tests", the analysis is performed on the hair strand, not on the follicle beneath the scalp.
