At Accredited Drug Testing, we offer comprehensive hair follicle drug testing services in Clearlake Riviera, California. If a hair drug or alcohol test is what you require, our specialty is hair testing with centers available in every city Nationwide. Typically, 1.5 to 2 inches of hair from the scalp or body is sufficient for testing. These tests assess drugs, alcohol/ETG, or offer specialized testing options.

There's been an increasing trend in drug testing towards hair follicle tests in recent years. Employers, legal courts, and substance abuse experts now often choose hair testing over the traditional urine method. These tests benefit employers enforcing a strict no-drug policy, legal institutions, and individuals on probation. They offer a longer detection window for substance use, generally up to 90 days, are collected under supervision, and are almost foolproof to manipulate. For drug use within the past five days, however, urine tests remain the most reliable method.

What it is, How it works

Hair analysis has emerged as an effective method for detecting drug and alcohol consumption. The strands capture biomarkers within their fibers, offering a detailed record of substance use over an extended period. By collecting hair nearest to the scalp, one can achieve a detection window of up to three months for drugs and alcohol. Hair collection is straightforward, challenging to tamper with, and convenient to transport.

A sample measuring 1.5 inches, comprising roughly 200 strands (akin to the width of a #2 pencil), provides an ideal 100mg for initial and confirmatory testing. For EtG tests, enhancements, or tests exceeding 10 panels, a 150mg specimen is advisable. Utilizing a jeweler’s scale for measurement is suggested. If scalp hair is absent, a comparable quantity of body hair can be utilized. “Head hair” pertains solely to scalp hair, while “body hair” encompasses all other types (such as facial and axillary hair).

Overview of the Procedure

The laboratory processing of a drug test result involves four key stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning marks the initial entry of a sample into the lab's system, ensuring the sample's seal and shipment integrity, assigning a random LAN (Laboratory Accessioning Number), and completing data entry beyond what's available through electronic means.

Screening consists of a preliminary assessment for potential drug use. It's an economical method to exclude drug presence in most samples, but a positive screen must be verified for legal acceptance. Positively screened samples require further confirmation.

When a sample shows a presumptive positive during Screening, additional hair is extracted from the primary sample to prep for the Extraction phase. At this stage, drugs are isolated from hair at concentrations greatly lower than those found in other testing methods (such as urine or oral fluid), illustrating why hair analysis is the most complex to execute.

Positive screen verification is conducted through GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, all presumptive positive samples undergo washing as needed. This comprehensive lab process, from Accessioning to Confirmation, adheres to both CAP (College of American Pathologists) Hair guidelines and accreditation by ISO/IEC 17025 standards.

Benefits of Hair Drug Testing:

  • Extended detection period: Hair tests can detect drug usage up to 90 days, whereas urine tests offer a shorter detection timeframe.
  • Hard to manipulate: The accuracy of hair tests is high due to the difficulty in falsifying results.
  • Historical insight: They can illustrate drug use patterns over time, rather than just recent usage.

Drawbacks:

  • Inability to detect recent consumption: Typically, 5-7 days are required before drugs are traceable in hair.
  • Expense: Generally, hair tests cost more than alternative methods.
  • Result variability: Drug metabolite concentrations can be influenced by factors like hair color and individual growth variations.

Note: The term "hair follicle tests" is often misleading, as it's the hair strand itself that is analyzed, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Clearlake Riviera, hair follicle tests surpass urine tests in reliability and detection capabilities. While traditional urine tests detect recent usage, hair samples reveal drug use over extended periods. This comprehensiveness adds value to assessments, making hair tests a preferred choice.
