Hair Follicle Drug Testing - Cassel, CA

What it is, How it works

Hair testing has evolved into a pivotal instrument for detecting alcohol and drug consumption. By capturing biomarkers within the fibers of developing hair strands, hair offers a prolonged timeline of drug and alcohol history. When retrieved from near the scalp, hair can deliver a detection window for alcohol and various drugs extending up to roughly 3 months. Hair is straightforward to collect, moderately resistant to tampering, and convenient to transport.

A 1.5-inch segment comprising approximately 200 strands of hair (akin to the thickness of a #2 pencil) nearest to the scalp will yield 100mg of hair, which is the optimal amount needed for both screening and verification. For EtG, additional tests, and/or panels exceeding 10, 150mg of the sample is suggested. We advise measuring the sample on a jeweler's scale. In cases where scalp hair isn't accessible, a comparable quantity of body hair can be utilized. When we mention head hair, we're strictly referencing scalp hair. Body hair encompasses all other hair varieties (such as facial, axillary, etc.).

Process Overview

The four essential stages involved in processing a drug test result in the lab are Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the initial procedure of integrating a sample into the lab's framework. This step involves verifying the sample's seal and shipment correctness, allocating a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry absent in an electronic chain of custody arrangement.

Screening constitutes a rapid preliminary check for drugs of abuse. Although a cost-efficient method to exclude drug use in the bulk of samples, any positive screen necessitates confirmation to be considered valid in legal settings. Samples yielding a presumptive positive in Screening require further confirmation.

For samples reflecting a presumptive positive in the Screening phase, additional hair is extracted from the initial specimen for Extraction. During this phase, drugs are extracted from hair at significantly lower concentrations than alternative methodologies (such as urine or oral fluid), underscoring the complexity of performing hair drug screenings.

Verification of any positive screening outcome is executed through methods like GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives undergo washing prior to confirmation as required. The full laboratory process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and compliance with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests can trace drug use for as long as 90 days, contrasting with the shorter detection window of urine tests.
• Challenges in manipulation: It's exceptionally challenging to tamper with a hair drug test, thereby enhancing result accuracy.
• Offers historical insights: It can reveal a timeline of drug usage over an extended period, not merely recent consumption.

Limitations:

• Inability to confirm recent use: It generally takes around 5-7 days for drugs to become detectable in hair.
• Expense: Hair drug testing often incurs higher costs than alternative testing methods.
• Result variability: Variables such as hair coloration and personal disparities in hair growth can influence drug metabolite concentrations in hair.

Note: While commonly dubbed as "hair follicle tests", the analysis is conducted on the hair strand rather than the hair follicle beneath the scalp.
