Hair Follicle Drug Testing - La Vina, CA

What it is, How it works

Hair analysis is perceived as an effective method for detecting the usage of drugs and alcohol. The absorption of biomarkers by the strands of growing hair provides an extended history of alcohol and drug use. When collected near the scalp, hair can reveal a detection timeline of up to 3 months for alcohol and other drugs. Collecting hair is straightforward, resistant to tampering, and easy to transport.

A 1.5-inch hair sample consisting of approximately 200 strands, comparable to the diameter of a #2 pencil, yields 100mg of hair, the preferred amount for screening and confirmation procedures. For EtG, additional tests, or tests exceeding 10 panels, 150mg of sample is suggested. Utilize a jeweler's scale to measure the sample. If scalp hair isn't accessible, an equivalent portion of body hair can be collected. References to head hair specifically denote scalp hair. Body hair encompasses other hair types, such as facial and axillary hair.

Process Overview

There are four key phases in the lab processing of a drug test result: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the preliminary step involving the registration of a specimen into a lab's system. It includes ensuring the proper sealing and shipment of the sample, assigning a unique LAN (Laboratory Accessioning Number), and fulfilling additional data entry requirements not covered by an electronic chain of custody.

Screening serves as an initial evaluation for detecting drug abuse. While it's a cost-efficient strategy to dismiss drug use in most samples, any positive screen must be confirmed for court admissibility. Samples showing preliminary positive results in Screening require further confirmation.

Should a sample test positive during the Screening phase, additional hair is extracted from the original sample and processed for Extraction. At this stage, drugs are extracted from hair at significantly lower concentrations than alternative methods (e.g., urine or oral fluid), which makes hair drug testing the most complex method.

Confirmation of any positive result from Screening is done via GC/MS, GC/MS/MS, or LC/MS/MS. Presumtive positive samples undergo washing before confirmation as necessary. The comprehensive lab process from Accessioning to Confirmation is examined 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 testing can trace drug use for as long as 90 days, unlike urine tests which have a more limited detection period.
• Challenge to circumvent: Tampering with a hair drug test is quite difficult, thus ensuring more reliable outcomes.
• Reveals historical consumption: It outlines a timeline of drug use, rather than just recent intake.

Limitations:

• Incapability to identify recent use: Typically, 5-7 days are necessary for drugs to become detectable in hair.
• Expense: Hair drug testing usually incurs higher costs compared to alternate drug testing techniques.
• Variability in outcomes: Individual factors like hair color and growth variations can impact the level of drug metabolites present in hair.

Note: Although commonly called "hair follicle tests," the procedure involves examining the hair strand rather than the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In La Vina, CA, hair testing triumphs over urine tests with its extended detection period, which can identify drug use up to 90 days prior. This surpasses traditional urine tests and provides a more comprehensive view of an individual’s habits.
