Hair Follicle Drug Testing - Geyserville, CA

What it is, How it works

Hair testing is increasingly recognized as an effective method for identifying drug and alcohol consumption. Hair captures a long-term record of alcohol and drugs by embedding biomarkers within the fibers of the developing hair strand. When sampled near the scalp, hair can offer a detection period of roughly 3 months for alcohol and other drugs. Hair collection is straightforward, resistant to tampering, and convenient to transport.

A 1.5-inch segment of around 200 hair strands (comparable to the thickness of a #2 pencil) nearest to the scalp yields 100mg of hair, which is the recommended amount for screening and confirmation. For EtG, additional tests, and/or tests beyond 10 panels, a sample of 150mg is advised. We suggest using a jeweler’s scale for weighing the specimen. If scalp hair is absent, an equivalent measure of body hair can be taken. When mentioning head hair, we specify scalp hair only. Body hair pertains to all other hair forms (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result involves four key steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the initial handling of a sample into a laboratory's system. This step includes confirming that the sample was correctly sealed and shipped, allocating a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry omitted by an electronic chain of custody system.

Screening involves an initial brief assessment for drugs of abuse. Though Screening is a cost-efficient method to eliminate drug usage in most samples, a positive result needs confirmation to be valid in court. Samples that show presumptive positivity in Screening require additional confirmation.

If a sample shows presumptive positivity in the Screening phase, more hair is extracted from the original specimen and prepped for Extraction. In this phase, drugs are isolated from hair at a considerably lower concentration than in other methods (e.g., urine or oral fluid), which is why hair drug testing is the most complex methodology to execute.

Confirmation of any positive Screening result is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing prior to confirmation as necessary. The comprehensive laboratory process from Accessioning to Confirmation is audited under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for up to 90 days, unlike urine tests which have a shorter detection span.
• Hard to adulterate: It is exceedingly tough to tamper with a hair drug test, ensuring more accurate results.
• Tracks historical usage: It provides a record of drug usage over time, not merely recent consumption.

Limitations:

• Inability to detect recent consumption: It requires about 5-7 days for drugs to be apparent in hair.
• Expense: Hair drug tests tend to be pricier than other drug testing techniques.
• Variable results: Factors such as hair color and individual differences in hair growth can influence the concentration of drug metabolites in the hair.

Note: Although often termed "hair follicle tests", the test analyzes the hair strand rather than the follicle beneath the scalp.
