In Pasadena, California, complete hair follicle drug testing is offered by Accredited Drug Testing. If a hair drug or alcohol assessment is necessary, our particular expertise lies in hair testing with availability nationwide. Typically, 1.5 to 2 inches of hair from the head's crown or body is required. These tests are capable of detecting drugs, alcohol/ETG, or other specified options.

Recently, the increased adoption of hair follicle drug tests is evident in the landscape of drug testing methods. Many employers, legal systems, and substance abuse experts now prefer these over traditional urine tests. These tests align with zero-tolerance policies held by employers, judicial requirements, and probation conditions. Their significant advantage lies in their extended drug detection span of up to 90 days and with an observed collection process, making evasion difficult. That said, urine tests remain the most effective for drug use detection within the past 5 days.

What it is, How it works

Hair analysis has emerged as an effective method for identifying drug and alcohol consumption. Hair retains a historical record of substance use by embedding biomarkers within the strands. Collected near the scalp, hair samples can reveal drug and alcohol presence over an approximate timeframe of three months. This method is user-friendly for collection, challenging to tamper with, and convenient for transportation.

A segment measuring 1.5 inches, consisting of around 200 hairs (roughly the diameter of a #2 pencil), will yield 100mg of hair, ideal for screening and verification. For EtG, additional substances, or testing beyond 10-panel assortments, a specimen weighing 150mg is suggested. A jeweler’s scale should be used for precise measurement. If scalp hair collection isn't possible, a comparable amount of body hair is acceptable. Head hair refers exclusively to scalp hair, while body hair includes other types such as facial and axillary.

Process Outline

The laboratory analysis of a drug test result encompasses four pivotal stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails entering a sample into a lab’s system. This process ensures the sample’s seal and shipment were intact, assigns a unique LAN (Laboratory Accessioning Number), and completes any manual data input absent from an electronic chain of custody.

Screening is a preliminary evaluation to identify drug abuse. Though a cost-efficient method to exclude drug use in most samples, a positive screen must be confirmed for legal proceedings. Presumptively positive results require follow-up confirmation testing.

Upon a presumptive positive in Screening, additional hair is extracted from the primary sample for Extraction. This phase involves retrieving drugs from hair at concentrations lower than those in other methods (e.g., urine or saliva), highlighting hair testing's intrinsic complexity.

Positive results are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS technologies. Presumptive positives undergo requisite washing before confirmation. The entire process, from Accessioning to Confirmation, adheres to CAP (College of American Pathologists) Hair designation and complies with ISO / IEC 17025 standards.

Benefits of hair drug testing:

  • Extended detection period: Capable of unveiling drug use for up to 90 days, surpassing urine tests’ shorter timeframe.
  • Increased fidelity: Hair tests are notably resilient to tampering, enhancing result reliability.
  • Chronological insights: Offers a detailed timeline of drug utilization, beyond recent consumption.

Drawbacks:

  • Inability to spot recent usage: Drugs typically take 5-7 days to be traceable in hair.
  • Expense: Hair analyses generally incur higher costs than alternate testing methodologies.
  • Result variability: Elements like hair color and personal growth differences can influence metabolite concentration.

Note: Commonly dubbed "hair follicle tests", these actually evaluate the hair strand, excluding the follicle beneath the scalp.

Frequently Asked Questions

A hair follicle drug test analyzes a small sample of hair to detect a history of drug use over time. Because drug metabolites are incorporated into hair as it grows, this method can show patterns of use instead of just recent exposure. It is frequently used for legal and court requirements, long-term monitoring, and high-trust workforce screening.
Standard hair drug testing typically reflects drug use over approximately a 90-day period, based on the length of hair collected at the time of testing. Longer hair can sometimes reflect a longer time frame, and extremely short hair can reduce that window.
Hair drug testing commonly screens for marijuana/THC, cocaine, opiates/opioids, amphetamines/methamphetamines, and PCP. In many cases, additional expanded panels may be requested to include other substances.
Yes. If the donor's head hair is too short or unavailable, body hair may be collected as an alternative. The collector will document the source of the sample. This allows testing even for individuals with recently cut or shaved head hair.
