Accredited Drug Testing provides thorough hair follicle drug evaluations in San Anselmo, California. Should you require a hair-related drug or alcohol check, we excel in hair analyses, with facilities in all major cities across the nation ready to conduct such tests. Having hair between 1.5 to 2 inches on the head or body suffices in most instances. Hair assessments offer insights into drugs, alcohol/ETG, or other customizable options.

The approach to drug evaluation has increasingly favored hair follicle analysis over recent years. Numerous employers, legal entities, and substance management experts now opt for hair over traditional urine exams. Hair follicle tests benefit entities with zero-tolerance drug stances, courts, and individuals under probation. Their chief advantage is an extended trace period for substances, reaching back up to 90 days, coupled with an unobtrusive collection process and resistance to tampering. However, for identifying recent drug use within five days, urine tests remain superior.

What it is, How it works

Utilizing hair testing has become recognized as an effective method for revealing drug and alcohol consumption. Hair captures long-term evidence of substances by embedding biomarkers within the fibers of the maturing hair shaft. By collecting hair near the scalp, it can offer an approximate three-month detection period for alcohol and drugs. The collection process for hair is straightforward, somewhat challenging to tamper with, and convenient for shipping.

A 1.5-inch portion comprising roughly 200 hair strands (comparable in size to a #2 pencil) nearest to the scalp yields 100mg of hair, which is the optimal sample size for both initial screening and further analysis. For EtG testing, additional analyses, and/or examinations exceeding 10 panels, a 150mg specimen is advised. We suggest utilizing a jeweler’s scale to measure the specimen's weight. Should scalp hair be unavailable, a comparable quantity of body hair may be utilized. When referencing head hair, it pertains exclusively to scalp hair. Body hair refers to any other hair type (such as facial, axillary, etc.).

Procedure Overview

The laboratory processing of a drug test result encompasses four primary steps: Accessioning, Screening, Extraction, and Confirmation.

The Accessioning phase involves the initial integration of a sample into a lab's system. This entails verifying proper sealing and shipping of the sample, assigning a unique LAN (Laboratory Accessioning Number), and fulfilling any supplemental data entry required, not included by an electronic chain of custody system.

The Screening phase involves an expedited preliminary examination for substance abuse. While Screening provides a cost-efficient method to eliminate drug usage across most samples, to be court-admissible, a positive screening requires confirmation. Any samples with presumptive positive results from Screening must undergo additional confirmation.

Should a sample exhibit a presumptive positive result in the Screening phase, additional hair is extracted from the initial sample in preparation for Extraction. During Extraction, substances are retrieved from hair at considerably lower concentrations compared to other methods (such as urine or oral fluid), making hair drug screening the most complex methodology to execute.

GC/MS, GC/MS/MS or LC/MS/MS methods are employed to confirm any positive screening results. Any samples with presumptive positive outcomes are cleansed before confirmation when necessary. The whole laboratory process from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair classification and is accredited to comply with ISO / IEC 17025 standards.

Benefits of hair drug testing:

  • Extended detection period: Hair drug tests are capable of identifying drug usage up to 90 days, unlike urine tests which have a shorter detection timeframe.
  • Challenging to manipulate: Manipulating a hair drug test is exceedingly difficult, ensuring more precise results.
  • Supplies historical information: It offers insight into drug usage patterns over time, beyond recent consumption.

Constraints:

  • Incapable of detecting recent use: It takes roughly 5-7 days for substances to become traceable within hair.
  • Expense: Hair drug testing is typically costlier compared to alternative drug testing procedures.
  • Result variability: Elements like hair color and personal hair growth variations can influence drug metabolite concentrations in hair.

Important: Although frequently termed as "hair follicle tests", this examination evaluates the hair shaft, not the follicle found beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Frequently Asked Questions

A hair follicle drug test analyzes a small sample of hair to detect a history of drug use over time.

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.
