Hair Follicle Drug Testing - Dry Prong, LA

What it is, How it works

Hair assessments are increasingly recognized as an effective means for identifying usage of drugs and alcohol. By capturing biomarkers within the strands, hair offers an extended historical record of these substances. When sampled close to the scalp, hair can reflect a substance use timeline of up to 3 months. Hair collection is straightforward, moderately resistant to tampering, and convenient to transport.

A 1.5-inch segment comprising approximately 200 hair strands (similar to the width of a #2 pencil) nearest the scalp yields 100mg, the preferred amount for testing and verification. For EtG, additional tests, or those exceeding 10 panels, a specimen weight of 150mg is advisable. It's best if the sample is measured with a jeweler’s scale. If head hair is absent, an equivalent quantity of body hair may be used. "Head hair" specifically denotes scalp hair, whereas "body hair" indicates all other types (e.g., facial, axillary).

Process Overview

The laboratory analysis of a drug test result primarily involves Accessioning, Screening, Extraction, and Confirmation steps.

Accessioning pertains to the preliminary incorporation of a sample into the lab's system, ensuring proper sealing and transport, assigning a unique LAN (Laboratory Accessioning Number), and completing any needed data entry not managed by an electronic chain of custody.

Screening provides an initial rapid assessment for drugs of abuse. Though a cost-effective method for excluding drug use from most samples, any sample yielding a positive screen must be further verified to be court-admissible. Presumptive positives in Screening require subsequent confirmation.

For any sample with a presumptive positive result in Screening, additional hair from the original sample is readied for Extraction. In this process, drugs are extracted at much lower concentrations than in alternative methods (like urine or oral fluid), making hair drug screening particularly challenging.

Verification of any positive screen result is completed through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptively positive samples undergo washing before confirmation if necessary. The lab process, from Accessioning to Confirmation, is evaluated under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests have the capacity to identify drug use up to 90 days past, in contrast to urine tests with shorter detection periods.
• Resistance to manipulation: It is notably challenging to deceive a hair drug test, enhancing result reliability.
• Cumulative data provision: It offers insight into drug use patterns over time, not just recent usage.

Limitations:

• Inability to detect recent usage: There is a 5-7 day period before drugs become detectable in hair.
• Expense: Hair drug assessments tend to incur higher costs than other drug testing methods.
• Result variability: Factors like hair color and individual hair growth differences can impact drug metabolite concentration in hair.

Note: Although often labeled as "hair follicle tests", the analysis is performed on the hair strand rather than the scalp's hair follicle.

Why Hair Follicle Testing Beats Urine Testing

In Dry Prong, LA, hair follicle tests surpass urine testing due to their superior accuracy and extended detection capabilities. Unlike urine tests, hair testing can reveal substance use up to 90 days.

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.
