Hair Follicle Drug Testing - North San Ysidro, NM

What it is, How it works

Hair examinations have emerged as an effective means for identifying alcohol and drug consumption. Hair retains a lengthy history of substance use by encapsulating indicators within the strands of the developing hair. When extracted near the scalp, hair can offer roughly a 3-month period for identifying substances such as alcohol and drugs. Hair is easy to collect, less vulnerable to tampering, and simple to transport.

A sample measuring 1.5 inches with approximately 200 hair strands (around the thickness of a #2 pencil) near the scalp will yield 100mg of hair, suitable for both preliminary screening and verification. For EtG, additional tests, and/or tests exceeding 10 types, a specimen quantity of 150mg is advised. Utilization of a jeweler’s scale is suggested for weighing the sample. In the absence of scalp hair, a similar amount of body hair can suffice. By head hair, we mean solely scalp hair, whereas body hair encompasses all other categories (facial, axillary, etc.).

Process Overview

The laboratory procedure for drug test analysis comprises four essential steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the initial integration of a sample into a laboratory system. This step involves confirming that the sample was correctly sealed and transported, assigning an arbitrary LAN (Laboratory Accessioning Number), and completing any required data entry missing from an electronic custody chain system.

Screening involves an initial broad assessment for substances of abuse. While Screening is an affordable method to dismiss substance usage in the majority of samples, a positive screening outcome requires validation for court acceptability. Samples yielding presumptive positives in Screening necessitate additional confirmation.

Should a sample register as presumptively positive during Screening, additional hair is taken from the initial sample and prepared for Extraction. During this phase, substances are withdrawn from hair at significantly lower densities than alternate methodologies (e.g., urine or oral fluid), which reasons hair drug assessment as the most challenging to conduct.

Verification of any positive screening result is executed via GC/MS, GC/MS/MS, or LC/MS/MS. All initial positive samples undergo washing prior to necessary confirmation. The comprehensive laboratory procedure from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair categorization and the accreditation of ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection duration: Hair drug assessments can detect substance consumption up to 90 days, unlike urine assessments which have a more limited detection span.
• Cheating deterrence: Cheating on a hair drug evaluation is exceptionally difficult, enhancing result precision.
• Historical data insight: It offers a record of substance usage over time, not limited to recent use.

Limitations:

• Inability to identify recent use: It requires about 5-7 days for substances to become visible in hair.
• Expense: Hair drug evaluations typically cost more than other substance testing techniques.
• Result variability: Elements such as hair hue and personal differences in hair growth can influence the density of drug biomarkers in hair.

Clarification: Though commonly termed "hair follicle assessments," the test analyzes the hair shaft 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.
