Hair Follicle Drug Testing - Wofford Heights, CA

What it is, How it works

Hair testing has emerged as a robust method for detecting drug and alcohol use. It offers an extensive history by encasing biomarkers within the hair as it grows. When taken near the scalp, hair extends a potential detection period of around three months for alcohol and drug usage, making it easy to collect, ship, and harder to tamper with.

A sample of 1.5 inches, with roughly 200 hairs (comparable to a #2 pencil) from near the scalp, delivers 100mg of hair—an optimal amount for screening and confirmation. For EtG additions or tests beyond 10 panels, it's advisable to use 150mg of hair. Using a jeweler’s scale to weigh the specimen is recommended. If scalp hair isn't available, a similar quantity of body hair can be harvested. Here, 'head hair' specifically refers to scalp hair, while 'body hair' signifies all other types (facial, axillary, etc.).

Process Overview

The laboratory’s drug testing workflow includes Accessioning, Screening, Extraction, and Confirmation.

Accessioning is where the sample initially integrates into the lab system, ensuring it was properly sealed and shipped, issuing a random LAN (Laboratory Accessioning Number), and covering any additional data entry absent from an electronic chain of custody system.

Screening provides an initial overview for drugs of abuse. Though Screening is cost-efficient for negating drug use on most samples, any positive findings must undergo confirmation for judicial acceptance. Samples testing positive at this stage need secondary confirmation.

In cases where a sample shows positive at the Screening stage, further hair is extracted from the original specimen and readied for Extraction. During this phase, drugs are extracted from hair at concentrations much lower than other methods (like urine or oral fluid), which attributes to hair drug testing's complexity.

GC/MS, GC/MS/MS, or LC/MS/MS conducts positive Screening result confirmations. Any samples flagged as presumptive positive undergo washing before confirmation if necessary. From Accessioning to Confirmation, the entire process is subject to review under both the CAP (College of American Pathologists) Hair designation and the ISO/IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug analyses can detect substance use for an approximate 90-day span, in contrast to the limited window of urine tests.
• Low risk of tampering: The difficulty in altering a hair drug test enhances result accuracy.
• Insightful historical data: It outlines a drug use pattern over time, rather than just recent usage.

Limitations:

• Inability to detect recent use: Drugs become detectable in hair roughly 5-7 days following use.
• Expense: Hair drug tests typically incur higher costs than other drug testing techniques.
• Variability in results: Components like hair color and individual hair growth differences can influence drug metabolite concentration in hair.

Note: Commonly termed "hair follicle tests", this test actually evaluates the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Wofford Heights, CA, hair follicle testing outshines urine tests in several aspects. The detection window of hair tests is substantially longer, reaching up to 90 days, offering a more comprehensive view of substance use. Unlike urine tests, hair analysis captures a broader range of substances, thus providing more accurate and reliable results.

Urine tests, while effective for short-term detection, fall short in detecting historical substance use. Hair follicle tests, with their enhanced sensitivity, ensure a more thorough and definitive analysis, making them the preferred choice for many employers and legal entities in the area.
