Hair Follicle Drug Testing - Country Club, CA

What it is, How it works

Seen as a robust method, hair testing detects both drug and alcohol consumption. It chronicles a longer-term usage by capturing biomarkers in the fibers of the hair strand as it grows. When collected near the scalp, hair can reveal up to about three months of alcohol and drug consumption. It's easy to collect, rather tamper-resistant, and straightforward to transport.

A sample of hair approximately 1.5 inches long, consisting of around 200 strands (roughly equivalent to a #2 pencil) near the scalp ensures 100mg of hair, which is optimal for both screening and confirmation. For tests like EtG, add-ons, or more extensive panels over 10, 150mg is preferable. We advise weighing the hair on a jeweler’s scale. Should scalp hair not be available, a similar amount of body hair is suitable. By head hair, we mean only scalp hair. Body hair encompasses all other types (such as facial or axillary hair).

Process Overview

There are four primary steps in processing a lab drug test result: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, the sample is introduced into the lab system. It entails confirming the sample’s seal and shipping, assigning it a random LAN, and completing any necessary data not covered by an electronic chain of custody system.

Screening is a preliminary assessment for drug presence. Though cost-effective and useful to rule out drug use in most samples, any positive screening result must be confirmed for it to be legally valid. Presumptive positives from Screening necessitate secondary confirmation.

If a sample tests presumptively positive in Screening, additional hair is taken from the original specimen for Extraction. Drugs are extracted at lower concentrations compared to other methods (such as urine or oral fluid), making hair drug testing particularly complex.

Positive results in Screening are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo cleansing before confirmation if necessary. The entire laboratory process, from Accessioning to Confirmation, is audited under the CAP Hair designation and meets ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair tests can detect drug use up to 90 days, whereas urine tests have a shorter span.
• Manipulation resistant: Cheating a hair drug test is notably difficult, yielding more accurate outcomes.
• Historical insight: Offers a record of drug usage patterns over time, not just recent intake.

Limitations:

• Lacks in detecting recent consumption: Drugs become detectable in hair approximately 5-7 days post-use.
• Higher cost: Hair drug testing typically incurs greater expenses than other testing approaches.
• Result variability: Factors like hair color and individual hair growth differences can influence drug metabolite concentrations in hair.

Note: Although frequently dubbed "hair follicle tests", the test actually examines the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

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.
