Hair Follicle Drug Testing - Winfield, PA

What it is, How it works

Hair testing has gained recognition as an effective means for identifying drug and alcohol consumption. Hair retains a comprehensive record of alcohol and other drugs by capturing biomarkers within the fibers of the maturing hair strand. When obtained near the scalp, hair can offer up to roughly a 3-month detection period for alcohol and other drugs. Hair collection is straightforward, relatively challenging to tamper with, and convenient to transport.

A 1.5-inch segment comprising about 200 hair strands (around the diameter of a #2 pencil) nearest to the scalp will yield 100mg of hair, the optimal sample for both screening and verification. For EtG, additional tests and/or panels exceeding 10, 150mg of the sample is advised. We suggest using a jeweler's scale to weigh the specimen. If scalp hair is not accessible, a comparable quantity of body hair may be gathered. When referring to head hair, we mean scalp hair exclusively. Body hair indicates all other types of hair (facial, axillary, etc.).

Process Overview

The primary steps in laboratory processing for a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the preliminary processing of a sample into the laboratory's system. This encompasses confirming that the sample was appropriately sealed and transported, generating a random LAN (Laboratory Accessioning Number), and fulfilling any extra data input not supplied by an electronic chain of custody system.

Screening involves an initial rapid assessment for drugs of abuse. While Screening is a cost-efficient method to eliminate drug usage from the bulk of samples, a positive screen requires confirmation to hold up in a court of law. Any samples that show presumptive positives in Screening necessitate further confirmation.

If a sample shows presumptive positives during the Screening phase, additional hair is extracted from the initial specimen and prepared for Extraction. In this phase, drugs are removed from hair at a significantly reduced concentration compared to other techniques (e.g., urine or oral fluid), highlighting the complexity of hair drug screening.

Confirmation of any positive screening result is performed via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing prior to confirmation if needed. The entire lab process from Accessioning to Confirmation is evaluated according to both CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation 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 feature a shorter detection period.
• Hard to manipulate: Cheating a hair drug test is quite difficult, ensuring the results are more trustworthy.
• Offers historical insights: It can outline a pattern of drug use over a timeframe, not just recent consumption.

Limitations:

• Lacks recent use detection: It usually takes around 5-7 days for drugs to become traceable in hair.
• Expense: Hair drug tests are generally pricier than other drug testing methods.
• Result variability: Factors like hair color and personal differences in hair growth can impact drug metabolite concentrations in hair.

Note: Although commonly termed "hair follicle tests", the test analyzes the hair strand itself and not the 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.

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.
