Hair Follicle Drug Testing - Lynch, MD

What it is, How it works

Using hair for testing has emerged as a compelling way to detect drug and alcohol consumption. Hair provides a prolonged record of alcohol and drug usage by embedding biomarkers within the hair strand's fibers as they grow. When taken close to the scalp, hair can offer roughly a 3-month detection period for substances. Collecting hair is straightforward, challenging to tamper with, and simple to transport.

A sample measuring 1.5 inches consisting of around 200 hair strands (roughly the thickness of a #2 pencil) nearest to the scalp yields 100mg of hair, which is the preferred sample size for screening and verification. For EtG, additional tests, or panels exceeding 10, a 150mg sample is advised. It is recommended to weigh the sample using a jeweler’s scale. Should scalp hair be unavailable, an equivalent quantity of body hair can be obtained. "Head hair" specifically denotes scalp hair, while "body hair" pertains to all other types (facial, axillary, etc.).

Process Overview

The laboratory analysis for a drug test involves four key stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the preliminary stage where a sample enters a laboratory's workflow. This step includes confirming proper sample sealing and shipping, generating a unique LAN (Laboratory Accessioning Number), and completing any necessary data entry not covered by an electronic chain of custody system.

Screening performs an initial assessment for substance abuse indicators. Although Screening is a cost-efficient means to negate drug use for most samples, a positive outcome demands verification to be upheld in court. Screening presumptive-positive results necessitate subsequent confirmation.

If Screening indicates a presumptive positive, additional hair is taken from the initial sample for Extraction. In this phase, drugs are extracted from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), illustrating why hair drug screening is the most intricate to execute.

Positive screening findings undergo Confirmation via GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives are washed prior to confirmation where necessary. The complete laboratory procedure from Accessioning through to Confirmation is inspected under the CAP (College of American Pathologists) Hair classification and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests detect drug usage spanning up to 90 days, unlike urine tests that have shorter detection times.
• Hard to manipulate: Cheating on a hair drug test is notably challenging, leading to reliable outcomes.
• Historical usage indication: The test illustrates a timeline of drug usage, beyond just recent activity.

Limitations:

• Cannot pinpoint recent consumption: It requires 5-7 days for drugs to become traceable in hair.
• Expense: Hair drug testing incurs higher costs than other testing forms.
• Result variability: Elements such as hair color and personal differences in hair growth affect drug metabolite levels in hair.

Note: Often termed "hair follicle tests," these tests assess the hair strand itself rather than the follicle underlying the scalp.

Why Hair Follicle Testing Beats Urine Testing

Hair follicle testing in Lynch, MD triumphs over traditional urine tests owing to superior detection capabilities. Unlike urine tests, hair tests capture drug use over a longer duration, providing greater insight. This longer detection window allows employers to assess more accurately an individual's substance use history.

While urine tests can detect recent substance use, hair tests offer a broader view. They provide unbeatable detection accuracy and reduce the risk of sample tampering, ensuring a credible testing process.

Extended Detection Window

The hair follicle testing method in Lynch, MD provides an extended detection window, reaching up to 90 days. This long span allows employers a comprehensive overview of an individual's drug history. Unlike shorter-span tests, this expansive period unveils patterns of recurrent drug use.

Employers can rely on hair tests to capture detailed substance use histories that urine tests simply cannot provide. This comprehensive tracking is invaluable for policies targeting long-term drug abstinence.

Tamper-Resistant Testing Method

In Lynch, MD, hair follicle tests provide a nearly tamper-resistant method of testing. With rigorous collection processes, these tests significantly mitigate the risk of sample adulteration and manipulation, ensuring reliable and trusted results.

Unlike other testing types, hair samples cannot be easily adulterated or substituted, thereby strengthening the validity of the results. This makes them an excellent choice for effective and reliable drug screening programs.

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.
