Hair Follicle Drug Testing - Vernon, CA

What it is, How it works

Hair analysis has emerged as an effective method for detecting substance use, given its ability to encapsulate long-term biomarkers in the fibers as hair grows. Hair samples taken near the scalp offer a detection period of up to around three months for substance consumption. It's easy to gather, challenging to contaminate, and straightforward to transport.

A hair sample measuring 1.5 inches and containing roughly 200 strands, comparable to the diameter of a #2 pencil, yields around 100mg, which is optimal for both screening and later confirmation. For tests involving EtG, additional markers, or more than 10 substances, it's advised to prepare a 150mg specimen. Using a jeweler’s scale for precise weighing of the specimen is recommended. If scalp hair is not accessible, an equivalent amount of body hair can be acquired. The term 'head hair' pertains solely to scalp hair, whereas 'body hair' includes all other types (facial, axillary, etc.).

Process Overview

The laboratory analysis of drug test samples encompasses four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the sample's initial registration into the laboratory's system, including verification of proper sealing and shipment, assignment of a random LAN (Laboratory Accessioning Number), and any ancillary data input not handled by an electronic chain of custody system.

Screening serves as the preliminary evaluation for substances of abuse. Though cost-efficient for determining the absence of drugs in many samples, a screening that returns positive must be confirmed for legal acceptance. Any preliminarily positive samples require further verification.

Should a sample show a presumptive positive at Screening, additional hair from the initial batch is prepared for Extraction. This phase involves removing drugs from hair at lower concentrations compared to other methods (e.g., urine or oral fluids), highlighting the complexity of hair drug testing.

Confirmation of any positive screening result is done using GC/MS, GC/MS/MS or LC/MS/MS technology. All samples presumed positive undergo a washing process if necessary before confirmation. The complete laboratory procedure from Accessioning to Confirmation is inspected under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug assessments can trace drug usage up to 90 days, unlike urine tests which have a reduced time frame for detection.
• Hard to falsify: Cheating a hair drug test is extremely challenging, ensuring more reliable results.
• Offers historical insight: It can reveal a pattern of substance use over an interval, not just recent activity.

Limitations:

• Incapable of detecting recent intake: It takes almost 5-7 days for drugs to appear in hair samples.
• Expense: Hair drug testing generally incurs higher costs than alternative drug testing techniques.
• Result inconsistencies: Variables such as hair color and individual hair growth differences can influence the concentration of drug metabolites.

Note: Although commonly termed as "hair follicle tests," the procedure evaluates the hair shaft, not the follicle beneath the scalp.
