Hair Follicle Drug Testing - Stem, NC

What it is, How it works

Hair assessments are now recognized as a formidable approach for identifying drug and alcohol usage. Hair retains a prolonged history of substance use by capturing biomarkers within the strands of growing hair. When extracted near the head, hair can offer a detection span of roughly 3 months for alcohol and other substances. Hair collection is straightforward, fairly resistant to tampering, and simple to transport.

An ideal sample for analysis and validation involves a 1.5-inch segment of roughly 200 hair strands (similar to the thickness of a #2 pencil) nearest to the scalp, amounting to 100mg of hair. For EtG, supplementary tests, and/or analyses exceeding 10 panels, a 150mg sample is advised. It is suggested to measure the sample using a jeweler’s scale. If scalp hair cannot be obtained, a comparable quantity of body hair may be used. When discussing head hair, we specifically mean scalp hair. Body hair includes all other types (facial, axillary, etc.).

Process Overview

The drug test laboratory processing involves four key stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the preliminary handling of a sample into a lab’s database, which encompasses ensuring the sample was correctly sealed and dispatched, assigning an arbitrary LAN (Laboratory Accessioning Number), and finalizing any supplementary data input absent in an electronic chain of custody framework.

Screening carries out an initial rapid evaluation for substance abuse. Although Screening offers a cost-efficient method to dismiss drug usage in most samples, a positive indication requires validation to hold up in legal procedures. Samples showing presumptive positive results during Screening need subsequent confirmation.

If a sample exhibits presumptive positivity during the Screening phase, further hair is extracted from the original sample for the Extraction process. At this stage, drugs are removed from hair at considerably lower concentrations than other techniques (e.g., urine or oral fluid), which renders hair drug screening the most intricate methodology to execute.

Positive Screening findings are authenticated through GC/MS, GC/MS/MS, or LC/MS/MS methods. All samples with presumptive positive results 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 adherence to ISO / IEC 17025 certifications.

Advantages of hair drug testing:

• Prolonged detection period: Hair drug evaluations can reveal drug consumption for as long as 90 days, unlike urine tests that have a more limited detection reach.
• Challenging to manipulate: It is exceptionally difficult to deceive a hair drug evaluation, rendering results more reliable.
• Yields chronological data: It provides a usage pattern over time, rather than only recent usage.

Limitations:

• Inability to identify recent use: It requires about 5-7 days for drugs to become discernible within hair.
• Expense: Hair drug evaluations generally incur higher costs than alternative testing approaches.
• Result variability: Elements like hair color and personal differences in hair growth may influence the concentration of drug metabolites in hair.

Note: Despite being termed "hair follicle tests," the analysis is conducted on the hair strand, not the follicle beneath the scalp.
