Hair Follicle Drug Testing - Central Colusa, CA

What it is, How it works

Hair testing is recognized as a potent method for identifying drug and alcohol consumption. Hair records a prolonged timeline of alcohol and other substances by encapsulating biomarkers within the strands during growth. When extracted closely to the scalp, hair can reveal a detection period extending up to about three months for alcohol and other substances. Hair collection is straightforward, hard to alter, and convenient to send.

A hair sample of 1.5 inches, consisting of approximately 200 strands (similar in size to a #2 pencil) closest to the scalp provides 100mg, the optimal sample size for analysis and verification. For EtG, add-ons, and/or analyses beyond 10 panels, 150mg of the sample is advised. Using a jeweler’s scale to weigh the specimen is suggested. In the absence of scalp hair, an equivalent volume of body hair can be collected. "Head hair" refers exclusively to scalp hair, while "body hair" pertains to all other types (e.g., facial, axillary).

Process Overview

The four principal phases in the laboratory processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the preliminary processing of a specimen into a lab’s system, ensuring the sample was adequately sealed and transported, assigning a random LAN (Laboratory Accessioning Number), and finalizing any supplementary data entry absent from an electronic chain of custody system.

Screening constitutes an initial rapid assessment for drugs of abuse. Although Screening is a cost-effective approach to exclude drug usage on the majority of samples, a positive screen warrants confirmation for court admissibility. Any samples with presumptive positives during Screening necessitate a secondary confirmation.

During the Screening phase, if a sample is presumptively positive, additional hair is retrieved from the initial sample and prepped for Extraction. At this juncture, drugs are derived from hair at substantially lesser concentrations than other methods (e.g., urine or oral fluid), underscoring the complexity of hair drug screening.

GC/MS, GC/MS/MS, or LC/MS/MS validates any positive screening outcomes. All presumptive positive samples undergo washing beforehand, as necessary. The complete lab process spanning Accessioning to Confirmation is assessed under both CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can trace drug use for as long as 90 days, surpassing the shorter window of urine tests.
• Hard to manipulate: Cheating a hair drug test is extremely challenging, enhancing result accuracy.
• Offers historical data: It can chart drug usage patterns over time, not solely recent intake.

Limitations:

• Incapable of detecting recent intake: It requires approximately 5-7 days for drugs to emerge as detectable in hair.
• Expense: Hair drug tests tend to be pricier compared to other drug testing methods.
• Result variations: Variables such as hair color and individual hair growth differences can influence the concentration of drug metabolites in hair.

Note: Commonly dubbed "hair follicle tests", the examination actually scrutinizes the hair strand rather than the follicle under the scalp.

What's New In Hair Follicle Drug Testing according to the Hair Drug Testing Experts

With its multidisciplinary nature, hair testing brings together researchers, scientists, and experts from various domains to develop innovative techniques, explore new methodologies, and address emerging concerns, responding to the ever-evolving challenges of drug abuse, therapeutic drug monitoring, and environmental exposures to pollutants.

The joint meeting of the Society of Hair Testing (SoHT) and the Italian Group of Forensic Toxicologists (GTFI) was organized in Verona, June 8–10, 2022, and hosted by the Legal Medicine team of the Verona University Hospital, directed by Franco Tagliaro together with Federica Bortolotti and Rossella Gottardo.

It served as a prominent platform for knowledge exchange and collaboration, facilitating groundbreaking advancements in hair testing and analysis. In this special issue of Drug Testing and Analysis, we aim to showcase the remarkable manuscripts presented at this significant event, shedding light on the latest research and highlighting the future directions in this field.

Novel Analytical Techniques: The Verona meeting witnessed the unveiling of cutting-edge analytical techniques, offering enhanced sensitivity, selectivity, and accuracy for drug testing. Remarkable advancements in sample preparation, detection, and identification of drug compounds have been presented. The manuscripts in this section presented novel approaches, such as multianalyte methods and on-line preparation which can enable rapid analysis and improve thorough forensic investigations.

Biomarkers and Pharmacokinetics: The identification and validation of reliable biomarkers and pharmacokinetic studies are fundamental aspects of drug testing and analysis.
