Offering comprehensive hair follicle drug testing services in Tollhouse, California, Accredited Drug Testing excels in hair testing with facilities in cities across the U.S. Hair samples must generally measure between 1.5 and 2 inches on the head or body. Hair testing can screen for drugs, alcohol/ETG, or other specialized options.

Over recent years, hair follicle drug tests have become increasingly popular in drug testing methods. They are preferred by employers, legal entities, and Substance Abuse professionals over standard urine tests. Hair follicle tests benefit zero-tolerance employers, court systems, and people on probation due to their extended detection period, typically up to 90 days. Collection is observed and difficult to falsify. However, urine tests remain the most reliable for detecting recent drug use within the last 5 days.

What it is, How it works

Hair analysis has emerged as an effective method for identifying consumption of drugs and alcohol, as it holds a long-term record by embedding biomarkers within the hair’s fibers as it grows. When taken near the root, hair enables an approximate 3-month time frame for detecting alcohol and substance use. Collecting hair is straightforward, challenging to tamper with, and is easily transported.

A 1.5-inch segment consisting of around 200 hair strands (akin to the size of a #2 pencil) nearest to the scalp yields 100mg of hair, the optimal quantity for analysis and confirmation. For EtG, supplemental, and/or tests exceeding 10 panels, 150mg of the sample is advised. We suggest measuring the sample on a jeweler’s scale. In instances where scalp hair is inaccessible, an equivalent amount of body hair may be gathered. When mentioning head hair, it pertains solely to scalp hair. Body hair encompasses all other types (such as facial, axillary, etc.).

Process Overview

The core stages in laboratory processing of a drug test result consist of Accessioning, Screening, Extraction, and Confirmation.

Accessioning comprises the preliminary integration of a specimen into a lab's system, involving assurance that the specimen was properly sealed and dispatched, assigning a random LAN (Laboratory Accessioning Number), and completing any remaining data entry absent from an electronic chain of custody system.

Screening comprises a preliminary inspection for substance abuse. While Screening is an economical approach to eliminate drug usage in most cases, a positive screen necessitates affirmation to be legally admissible. All samples presumptively positive in Screening require further confirmation.

Upon encountering a presumptive positive in the Screening phase, additional hair is extracted from the original sample and prepared for Extraction. During this phase, drugs are isolated from hair at substantially lower concentrations than other methods (ex. urine or oral fluid), making hair analysis the most intricate method to execute.

Confirmation of any positive screening outcome is carried out through GC/MS, GC/MS/MS or LC/MS/MS. All samples with presumptive positives undergo washing before confirmation as required. The comprehensive laboratory procedure from Accessioning to Confirmation undergoes scrutiny under both the CAP (College of American Pathologists) Hair designation and following ISO / IEC 17025 standards.

Advantages of hair drug testing:

  • Extended detection period: Hair drug tests can reveal drug usage for up to 90 days, in contrast to urine tests which have a shorter detection period.
  • Hard to deceive: Manipulating a hair drug test is exceedingly difficult, ensuring highly reliable results.
  • Provides usage history: It can reveal a pattern of drug usage across time, not merely recent consumption.

Limitations:

  • Inability to detect recent usage: There's typically a 5-7 day period before drugs become identifiable in hair.
  • Expense: Hair drug tests tend to be pricier than alternative testing methods.
  • Result variations: Variables like hair color and personal variations in hair growth can influence drug metabolite concentration in the hair.

Note: Often dubbed as "hair follicle tests," the assessment targets the hair strand rather than 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.

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.
