Hair Follicle Drug Testing - West End, TX

What it is, How it works

Hair testing has emerged as an effective means for detecting drug and alcohol consumption. Hair offers an extended timeline of drug and alcohol usage by capturing biomarkers within the fibers of the emerging hair strand. When obtained close to the scalp, hair can demonstrate up to about a 3-month detection cycle for drugs and alcohol. Hair is straightforward to gather, relatively hard to tamper with, and convenient for shipping.

A 1.5-inch portion of around 200 hair strands (roughly equivalent to a #2 pencil) closest to the scalp yields 100mg of hair, the optimal quantity for screening and confirmation. For EtG, add-ons, and/or tests beyond 10 panels, 150mg of hair is advisable. We suggest weighing the sample using a jeweler’s scale. In the absence of scalp hair, an equivalent quantity of body hair can be collected. When mentioning head hair, we mean scalp hair exclusively. Body hair encompasses all other hair types (facial, axillary, etc.).

Process Overview

The primary procedures involved in the laboratory processing of a drug test result encompass Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial handling of a sample into the lab’s system. This step incorporates verifying that the sample was securely sealed and shipped correctly, allocating a random LAN (Laboratory Accessioning Number), and completing any additional data entry not covered by an electronic chain of custody system.

Screening entails an initial expedited review for drugs of abuse. While Screening serves as a cost-efficient method to rule out drug usage for most samples, a positive screen must be verified to be acceptable in court. Any samples likely positive in Screening necessitate a secondary confirmation.

If a sample is likely positive during the Screening stage, additional hair is extracted from the primary specimen and prepared for Extraction. In this step, drugs are extracted from hair at a significantly lower concentration than in alternative methodologies (e.g., urine or oral fluid), which is why hair drug screening is acknowledged as the most challenging methodology to execute.

Confirmation of any positive screening outcome is executed through GC/MS, GC/MS/MS, or LC/MS/MS. All presumed positive samples undergo washing prior to confirmation as necessary. The complete laboratory procedure from Accessioning to Confirmation is appraised 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 cycle: Hair drug tests can identify drug use for up to 90 days, unlike urine tests which have a more limited detection cycle.
• Challenge in falsifying: It is exceedingly challenging to falsify a hair drug test, ensuring more accurate outcomes.
• Offers historical insight: It can reveal a pattern of drug use across a period, not merely recent use.

Limitations:

• Incapacity to detect recent usage: It takes about 5-7 days for drugs to become detectable in hair.
• Expense: Hair drug tests generally cost more than other drug testing alternatives.
• Result variations: Elements such as hair color and individual growth variations may influence the concentration of drug metabolites in the hair.

Note: Often labeled as "hair follicle tests," the testing process actually evaluates the hair strand and not the hair follicle 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. 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.
