Hair Follicle Drug Testing - Lafayette, CA

What it is, How it works

Hair testing has emerged as a potent method for detecting drug and alcohol consumption. Hair captures a prolonged history of alcohol and other substances by embedding biomarkers within the strands as they grow. When gathered near the scalp, it can offer up to a 3-month detection window for both alcohol and drugs. The collection of hair is straightforward, relatively resistant to tampering, and simple to transport.

A 1.5-inch segment of approximately 200 hair strands (roughly the size of a #2 pencil) nearest to the scalp yields 100mg of hair, the optimal sample for both screening and verification. For EtG, supplemental tests, and/or panels exceeding 10, 150mg of the sample is advised. We suggest weighing the sample with a jeweler’s scale. If scalp hair is inaccessible, an equivalent amount of body hair may be utilized. When mentioning head hair, we mean scalp hair exclusively. Body hair signifies all other hair forms (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result encompasses four major phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the sample's initial preparation into a laboratory’s system. This comprises verifying proper sealing and shipment of the sample, allocating a random LAN (Laboratory Accessioning Number), and filling in any data not supplied by an electronic custody chain system.

Screening entails a preliminary rapid assessment for substance abuse. Although Screening is cost-efficient for dismissing drug usage in most samples, a positive screen must be validated to be court-admissible. Samples that are presumptively positive in Screening call for further confirmation.

Should a sample be presumptively positive at the Screening phase, additional hair is extracted from the initial sample for Extraction. At this phase, drugs are extracted from hair at a much reduced concentration relative to other methods (e.g., urine or oral fluid), making hair drug screening one of the most challenging methodologies to administer.

Confirmation of any positive screening is executed through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo a wash prior to confirmation as necessary. The whole laboratory procedure from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests can uncover drug use for up to 90 days, in contrast to urine tests with a shorter detection span.
• Minimal cheating possibility: It's exceedingly difficult to deceive a hair drug test, thus the results are more reliable.
• Provides usage pattern: It can reveal a pattern of substance usage over time, not just recent activity.

Limitations:

• Incapable of detecting recent use: It takes around 5-7 days for substances to become traceable in hair.
• Expense: Hair drug tests generally incur higher costs than other testing methods.
• Results variability: Variables such as hair color and individual hair growth rates can influence drug metabolite concentration in hair.

Note: Although frequently termed "hair follicle tests", the examination evaluates the hair strand rather than the follicle beneath the scalp.
