Accredited Drug Testing provides comprehensive hair follicle drug screening in North Gate, California. If a hair drug or alcohol test is required, Accredited Drug Testing has expertise in hair testing with centers located in cities Nationwide capable of hair analysis. Typically, 1.5 to 2 inches of hair is necessary from the crown or the body. Such tests can check for drugs, alcohol/ETG, or support other customized hair assessments.

Lately, the prevalence of hair follicle drug testing has increased. This method is being favored by employers, courts, and substance abuse specialists over traditional urine tests. Hair tests cater to zero-tolerance policies and are utilized by the judiciary and probationary contexts. The key advantage is the extensive detection timeframe of up to 90 days, with observed collection making the test hard to manipulate, whereas urine tests remain superior for detecting recent drug use within 5 days.

What it is, How it works

Hair analysis has gained recognition as an effective means for identifying drug and alcohol consumption. Hair retains a prolonged record of alcohol and other substances by encasing markers in the structure of the developing hair strand. When collected near the scalp, it can offer a detection window for alcohol and other substances of up to three months. This method of collection is easy, somewhat resistant to tampering, and can be transported easily.

A 1.5-inch sample of roughly 200 hair strands (similar to the diameter of a #2 pencil) nearest to the scalp yields 100mg of hair, the perfect quantity for primary testing and verification. With EtG, additional tests, and/or more than 10-panel tests, 150mg of the sample is advised. Using a jeweler’s scale to weigh the sample is recommended. If scalp hair is not present, an equivalent quantity of body hair may be used. When discussing head hair, we mean scalp hair exclusively. Body hair encompasses all other hair types (facial, axillary, etc.).

Process Overview

The four key phases in the laboratory handling of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial phase of sample processing in a laboratory system. This step ensures that the sample was securely sealed and sent, assigns it a random LAN (Laboratory Accessioning Number), and completes any further data required outside an electronic custody chain system.

Screening provides an initial rapid assessment for substances of abuse. Screening is cost-efficient for ruling out drug use in most samples, but a positive finding requires further validation for legal admissibility. Samples testing positive in Screening mandate a secondary verification.

If a sample tests positive in Screening, more hair is extracted from the original specimen for the Extraction phase. Here, substances are isolated from hair at lower concentrations than in other methods (such as urine or saliva), hence why hair drug tests are challenging to perform.

Positive results from Screening proceed to Confirmation using GC/MS, GC/MS/MS, or LC/MS/MS methods. Presumptive positive samples undergo washing before confirmation as needed. Each laboratory phase from Accessioning to Confirmation is evaluated under the CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

  • Extended detection period: Hair tests can track drug use up to 90 days, unlike urine tests with shorter detection periods.
  • Resistant to manipulation: Cheating on a hair drug test is extremely difficult, ensuring result accuracy.
  • Historical insight: It reveals a pattern of drug usage over time rather than only recent use.

Limitations:

  • Inability to detect recent use: About 5-7 days are required for drugs to become detectable in hair.
  • Expense: Hair testing costs more than other testing techniques.
  • Result variability: Factors like hair color and personal hair growth differences can impact metabolite levels in hair.

Note: Although often named "hair follicle tests", it is the hair shaft analyzed, not the follicle under the scalp.
