Hair Follicle Drug Testing - Waldo, WI

What it is, How it works

Hair examinations have emerged as a robust method for identifying the use of drugs and alcohol. Hair encapsulates a lengthy history of alcohol and drug exposure by embedding biomarkers within the strands as they grow. Obtained near the scalp, hair offers a detection span of up to roughly three months for alcohol and drugs. Hair collection is straightforward, relatively resistant to tampering, and simple to mail.

A 1.5-inch segment of roughly 200 hairs (akin in width to a #2 pencil) nearest to the scalp yields 100mg, which is the perfect volume for evaluation and validation. For EtG, additional tests, and/or assessments exceeding 10 panels, 150mg is advisable. We advocate measuring the sample with a jeweler’s scale. If scalp hair cannot be obtained, a similar quantity of body hair may be used. When mentioning head hair, we refer solely to scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).

Process Overview

The principal phases involved in the lab processing of drug test findings are Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the primary processing of a sample into a lab’s framework. This involves ensuring the sample was properly sealed and dispatched, assigning a random LAN (Laboratory Accessioning Number), and completing any extra data entry that an electronic custody chain system doesn't cover.

Screening consists of an initial swift check for drug misuse. Though Screening economically excludes drug use in most samples, a confirmed positive outcome is essential for legal acceptability. Any samples presumptively positive at Screening demand secondary validation.

If a sample tests presumptively positive at the Screening phase, more hair is drawn from the original specimen and made ready for Extraction. Here, drugs are obtained from hair at a considerably reduced concentration than in other methods (e.g., urine or oral fluid), underscoring the complex nature of hair drug analysis.

Confirming any positive screening result involves the use of GC/MS, GC/MS/MS, or LC/MS/MS. All samples deemed presumptive positive undergo cleansing before confirmation as required. The comprehensive lab procedure, from Accessioning through Confirmation, is appraised under the CAP (College of American Pathologists) Hair criteria and the ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug usage for up to 90 days, surpassing the briefer detection period of urine tests.
• Hard to deceive: Cheating on a hair drug test is extremely challenging, enhancing the reliability of results.
• Offers historical perspective: It reveals a drug use pattern spanning a time frame, beyond immediate usage.

Limitations:

• Unable to detect recent usage: Typically, it takes 5-7 days for drugs to be identifiable in hair.
• Expense: Hair drug tests often incur higher costs compared to alternative testing methods.
• Inconsistent findings: Variables like hair color and individual differences in hair growth can impact drug metabolite levels in hair.

Note: Although frequently termed "hair follicle tests", the analysis scrutinizes the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

When comparing hair follicle to urine tests in Waldo, WI, the benefits become evident. Hair tests provide a more comprehensive detection period, securing more reliable and accurate results, while urine tests are best for short-term detection.

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. Furthermore, the SoHT meeting in Verona featured research on the identification and quantification of alcohol abuse biomarkers, their stability, and their correlation with exposure and other biomarkers.
