Hair Follicle Drug Testing - Crows Landing, CA

What it is, How it works

Hair examinations have emerged as an effective means for identifying both drug and alcohol consumption. Hair offers an extended timeline of substance intake by embedding biomarkers within the fibers of the developing hair. Collected from near the scalp, hair can yield a detection span of up to roughly three months for alcohol and other substances. It's straightforward to gather, less prone to tampering, and simple to transport.

A sample measuring 1.5 inches with around 200 hair strands (approximating the size of a #2 pencil) nearest the scalp equates to 100mg, which is the perfect quantity for both initial testing and verification. For EtG, additional analyses, and/or tests exceeding 10 panels, a specimen weighing 150mg is advised. We suggest using a jeweler’s scale to weigh the specimen. If head hair isn't accessible, a comparable quantity of body hair can be utilized. By head hair, we mean only scalp hair. Body hair includes all other varieties (face, underarms, etc.).

Process Overview

The principal stages in the lab processing for a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the initial handling of a specimen within a lab’s system. It involves verifying the correct sealing and shipping of the sample, assigning a randomized LAN (Laboratory Accessioning Number), and fulfilling supplementary data entries not covered by an electronic chain of custody system.

Screening denotes an initial rapid assessment for substance abuse. Though Screening is a budget-friendly method to rule out drug use in most cases, a positive screen requires confirmation to be legally valid. Samples with a presumptive positive result in Screening necessitate secondary confirmation.

When a sample is considered presumptively positive during Screening, additional hair is taken from the original specimen and prepared for Extraction. This phase entails extracting substances from hair at markedly lower concentrations compared to other methods (for example, urine or oral fluid), which accounts for the complexity of hair drug testing.

Confirmation follows any positive screening outcome through GC/MS, GC/MS/MS, or LC/MS/MS. Presumed positive samples undergo washing prior to confirmation if necessary. The entire lab workflow from Accessioning to Confirmation is audited 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 range: Hair drug assessments can uncover drug use for as long as 90 days, unlike urine assessments that have a shorter range.
• Difficult to deceive: Hair drug tests are notably hard to falsify, enhancing the accuracy of the results.
• Delivers historical insights: It reveals a usage trend over a prolonged period, rather than just recent usage.

Limitations:

• Inability to detect recent intake: It takes approximately 5-7 days for substances to be present in hair.
• Expense: Hair drug assessments generally incur higher costs than other testing methods.
• Result variability: Elements like hair color and personal differences in hair growth can impact the levels of drug metabolites in hair.

Note: Despite being commonly termed "hair follicle tests", the examination itself targets the hair strand, not the follicle located beneath 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.
