Hair Follicle Drug Testing - Coffee Creek, CA

What it is, How it works

Hair testing is now recognized as an effective method for identifying drug and alcohol consumption. Hair retains a long-term record of alcohol and drug use by embedding biomarkers within the fibers of its growing strands. When gathered near the scalp, hair can offer a detection timeframe of up to roughly three months for alcohol and drugs. Hair collection is straightforward, challenging to tamper with, and simple to transport.

A sample measuring 1.5 inches, consisting of approximately 200 hair strands (roughly the thickness of a #2 pencil) nearest the scalp provides 100mg of hair, the recommended amount for screening and confirmation. For EtG, additional tests, or tests exceeding 10 panels, 150mg of the sample is advisable. Utilizing a jeweler’s scale for weighing the sample is recommended. If scalp hair is lacking, an equivalent quantity of body hair can be collected. When discussing head hair, it pertains solely to scalp hair. Body hair encompasses all other hair varieties (facial, axillary, etc.).

Process Overview

The laboratory processing for a drug test outcome involves four critical stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial phase for integrating a sample into the laboratory system. This step involves ensuring the sample was properly sealed and dispatched, allocating a unique LAN (Laboratory Accessioning Number), and fulfilling any added data entry absent in an electronic custody chain system.

Screening serves as a preliminary rapid assessment for abuse substances. While cost-efficient for excluding drug use in most samples, positive screening results require confirmation to be valid in legal settings. Samples deemed presumptively positive during Screening necessitate secondary verification.

Samples presumed positive at the Screening stage have additional hair drawn from the original sample to prepare for Extraction. In this phase, drugs are extracted from hair at a much lower concentration compared to other techniques (such as urine or oral fluid), making hair drug testing one of the most challenging methods to conduct.

Confirmation for any positive screening result uses GC/MS, GC/MS/MS, or LC/MS/MS methods. Samples that show presumptive positivity are cleansed prior to confirmation as necessary. The entire lab process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair classification and ISO / IEC 17025 standards accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug testing can identify drug use for up to 90 days, unlike urine tests that have a shorter timeframe.
• Hard to manipulate: It is highly challenging to deceive a hair drug test, ensuring the results' accuracy.
• Historical data provision: It provides an overview of drug consumption patterns over a time span, not just recent intake.

Limitations:

• Incapable of detecting recent use: Drugs become detectable in hair approximately 5-7 days post-consumption.
• Expense: Hair drug tests are typically pricier than other testing methods.
• Result inconsistencies: Factors like hair color and individual differences in hair growth can influence drug metabolite concentrations in the hair.

Note: Commonly termed "hair follicle tests", the analysis is conducted on the hair strand, not the scalp's hair follicle

Why Hair Follicle Testing Beats Urine Testing

In Coffee Creek, CA, hair follicle tests are often favored over traditional urine analysis due to their superior detection accuracy and reliability. While urine tests are limited in their detection window, hair tests have the edge by capturing a more significant historical snapshot of drug usage. Consequently, this broad detection capability makes hair testing a preferred choice for employers seeking meticulous assessments.

Extended Detection Window

The benefit of choosing hair follicle testing in Coffee Creek, CA lies in its extended detection window—tracking substance use up to 90 days prior. This provides employers with an expansive view of an employee's or candidate's history, allowing a more informed decision-making process. The long-term tracing ability of hair tests undeniably aids in transparent and insightful evaluations.

Tamper-Resistant Testing Method

One of the biggest challenges in drug screening is ensuring the samples remain untampered. Hair follicle tests in Coffee Creek, CA effectively reduce tampering risks, giving dependable results. The process is resistant to external interference, presenting clear and dependable evidence of substance intake, reassuring stakeholders of the integrity of results.
