Hair Follicle Drug Testing - Wylliesburg, VA

What it is, How it works

Hair examinations have emerged as an effective means of identifying drug and alcohol consumption. Hair can capture a retrospective overview of alcohol and other substances by embedding biomarkers within the strands of hair as it grows. When retrieved near the scalp, hair can offer approximately a 3-month retrospective detection window for alcohol and other substances. Hair collection is straightforward, difficult to tamper with, and easy to transport.

A 1.5-inch segment containing roughly 200 hair strands (approximately the width of a #2 pencil) from the scalp can yield 100mg of hair, which is optimal for screening and verification. For EtG, additional requests, and/or tests beyond 10 panels, 150mg of the sample is advised. It is recommended to measure the sample using a jeweler’s scale. If scalp hair is not available, equivalent body hair may be gathered. References to head hair specifically denote scalp hair. Body hair encompasses all other types (facial, axillary, etc.).

Process Overview

The laboratory processing of drug test results involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial incorporation of a sample into a laboratory’s framework. This encompasses verifying that the sample was properly sealed and dispatched, assigning a random LAN (Laboratory Accessioning Number), and executing any supplementary data entry not provided by an electronic chain of custody system.

Screening involves an initial rapid assessment for substances of abuse. While Screening is an economical method to rule out drug use in most samples, a positive screen requires further confirmation to be valid in legal contexts. Presumptively positive samples in Screening necessitate a secondary verification.

If a sample tests presumptively positive during the Screening phase, additional hair is extracted from the initial sample and prepared for Extraction. During this phase, drugs are extracted from hair at a lower concentration compared to other methods (e.g., urine or oral fluid), which is why hair drug screening is the most challenging method to execute.

Confirmation of any positive screening result is facilitated via GC/MS, GC/MS/MS or LC/MS/MS. All samples with presumptive positives are cleansed prior to confirmation as necessary. The complete laboratory procedure from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests can detect drug use for up to 90 days, whereas urine tests have a more limited detection timeframe.
• Hard to deceive: It is challenging to tamper with a hair drug test, ensuring more credible results.
• Reveals historical patterns: It can depict a history of drug use over time, rather than just recent consumption.

Limitations:

• Inability to detect recent ingestion: It necessitates approximately 5-7 days for drugs to be traceable in hair.
• Expense: Hair drug analyses tend to be costlier than alternative drug testing methodologies.
• Result variability: Considerations like hair color and personal hair growth patterns can influence drug metabolite concentrations in the hair.

Note: Although often termed as "hair follicle tests", the analysis is performed on the hair strand, not the hair follicle beneath the scalp.
