Hair Follicle Drug Testing - San Juan Bautista, CA

What it is, How it works

Hair testing is recognized as a compelling method for uncovering drug and alcohol consumption. It offers a long-term record of substance use by encasing biomarkers within the fibers of the developing hair strand. When hair samples are taken close to the scalp, they can reveal drug use over a period of up to around three months. Hair samples are straightforward to collect, relatively hard to tamper with, and convenient to transport.

A 1.5-inch sample, approximately comprising 200 hairs (comparable to the thickness of a #2 pencil) nearest to the scalp, yields 100mg of hair, which is optimal for screening and verification. For EtG, additional tests, or those exceeding 10 panels, 150mg of the sample is advised. We suggest using a jeweler’s scale for precise weighing of the specimen. If scalp hair isn't available, an equivalent volume of body hair might be used. 'Head hair' refers specifically to scalp hair in this context, whereas 'body hair' encompasses all other types, such as facial and axillary hair.

Process Overview

Laboratory processing of drug test results encompasses four main stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the initial incorporation of a sample into the laboratory system. This phase involves confirming proper sealing and shipping of the sample, generating a random Laboratory Accessioning Number (LAN), and completing any supplemental data input not covered by an electronic chain of custody.

Screening serves as a swift preliminary assessment for drug abuse. While it is a cost-efficient method for dismissing drug use in most samples, a positive screen result must undergo confirmation to hold up in legal proceedings. Any samples that test as presumptively positive in Screening require further confirmation.

For samples that show presumptive positive results in Screening, additional hair from the original sample is extracted and prepped for Extraction. In this phase, drug substances are drawn out from hair at much lower concentrations than those found in alternatives like urine or oral fluid testing, contributing to the complexity of hair drug screening.

Any positive Screening finding undergoes Confirmation through techniques such as GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive specimens are washed before confirmation as needed. The entire process, from Accessioning to Confirmation, is subject to review under the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can spot drug use for as long as 90 days, unlike urine tests which have a shorter detection span.
• Resistance to manipulation: Cheating in hair drug tests is exceedingly challenging, ensuring more reliable results.
• Offers historical insights: It can chart a pattern of drug use across time, as opposed to merely recent use.

Limitations:

• Inability to detect immediate usage: Generally, it takes about 5-7 days for drugs to be traceable in hair.
• Expense: Hair drug testing methods tend to be pricier than other types.
• Inconsistencies in outcomes: Variables like hair color and personal differences in hair growth can influence drug metabolite concentration in hair.

Note: While often termed "hair follicle tests," these assessments examine the hair strand itself, 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.
