Hair Follicle Drug Testing - Big Creek, CA

What it is, How it works

Hair testing is recognized as an effective means for identifying drug and alcohol consumption. By embedding biomarkers within the fibers of an emerging hair strand, hair provides a prolonged record of alcohol and drug usage. When snipped near the scalp, hair can reveal up to roughly a three-month detection span for drugs and alcohol. It's straightforward to gather, resistant to tampering, and simple to dispatch.

A 1.5-inch segment comprising approximately 200 hair strands (similar to the size of a #2 pencil) nearest to the scalp yields 100mg of hair, which is the optimal sample for scrutiny and verification. For EtG, supplementary tests, or those exceeding 10 panels, the recommendation is 150mg of the specimen. We advise assessing the specimen's weight with a jeweler's scale. If scalp hair cannot be obtained, a comparable quantity of body hair may be gathered. References to head hair relate strictly to scalp hair. Body hair encompasses all other hair categories (such as facial, axillary, etc.).

Process Overview

The laboratory evaluation of drug test results involves four core stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the preliminary handling of a sample into a lab's framework. This process verifies proper sealing and shipment of the sample, assigns a random LAN (Laboratory Accessioning Number), and completes any outstanding data input absent from an electronic chain of custody system.

Screening consists of a preliminary fast analysis for drugs of misuse. Although Screening is a cost-effective method to exclude drug use in the majority of samples, a positive screen must undergo confirmation to be valid in legal settings. Samples that test presumptively positive in Screening necessitate secondary confirmation.

When a sample tests presumptively positive during the Screening phase, additional hair is drawn from the initial specimen and readied for Extraction. This step involves extracting drugs from hair at a significantly lower concentration compared to other methods (such as urine or oral fluid), marking hair drug screening as a challenging methodology to execute.

Confirmation of any positive Screening outcome is conducted through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptively positive samples undergo a cleansing before confirmation if needed. From Accessioning to Confirmation, the entire laboratory process is reviewed under the CAP (College of American Pathologists) Hair designation and conforms to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests can identify drug use for as long as 90 days, in contrast to urine tests, which have a more confined detection span.
• Hard to deceive: Cheating a hair drug test is notably tough, ensuring more precise results.
• Supplies historical data: It outlines a pattern of drug consumption over time, as opposed to merely recent use.

Limitations:

• Unable to detect recent use: It requires roughly 5-7 days before drugs become detectable in hair.
• Expense: Hair drug tests typically incur higher costs than other drug testing approaches.
• Result variations: Variables like hair color and individual hair growth differences can influence drug metabolite concentrations in hair.

Note: While frequently termed as "hair follicle tests", the actual test evaluates the hair strand and not the hair 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. The impact of hair treatments on the oxidation/decomposition of drugs in hair was also explored, as the long-term fate of drugs incorporated in the keratin matrix.
