Accredited Drug Testing offers a thorough hair follicle drug testing service in Tooleville, California. If you require a hair drug or alcohol test, Accredited Drug Testing is an expert in hair testing, with centers nationwide equipped to conduct such tests. Generally, 1.5 to 2 inches of hair from the head or body can be used. Hair tests may be conducted for drugs, alcohol/ETG, or other specific purposes.

In recent times, hair follicle drug tests have been increasingly adopted for drug testing. Many employers, courts, and substance abuse experts now prefer hair testing over traditional urine tests. Those parties require hair drug tests to enforce zero-tolerance drug use policies. A key benefit of hair testing is its extended drug detection window of up to 90 days, conducted through supervised collection, and is almost inviolable. Conversely, urine tests remain most precise for drug use within the prior 5 days.

What it is, How it works

Hair analysis is now recognized as a robust method for identifying drug and alcohol consumption. Hair strands secure a long-term record of alcohol and drug use by embedding biomarkers within the hair's fiber as it grows. A sample gathered near the scalp can offer a detection window of up to three months for both alcohol and drugs. The collection process is straightforward, alteration-resistant, and convenient for shipping.

A sample of hair measuring 1.5 inches and consisting of about 200 strands (approximately the diameter of a #2 pencil) nearest to the scalp yields 100mg of hair, which serves as the perfect quantity for both screening and confirmation. For tests such as EtG, additional tests, or those exceeding 10-panel screens, 150mg of the hair sample is advisable. Using a jeweler’s scale for precise measurement is suggested. If scalp hair is unattainable, a similar volume of body hair can be used instead. When referencing head hair, it indicates scalp hair solely. Body hair encompasses all other hair types, including facial and axillary.

Process Overview

The key phases in the lab processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the initial sample integration into a laboratory’s database. This stage ensures the sample has been properly sealed and shipped, assigns an arbitrary LAN (Laboratory Accessioning Number), and finalizes additional data entry absent from any electronic custody system.

Screening involves an initial cursory check for drugs of abuse. Although Screening is a cost-effective approach to exclude drug use in most samples, a positive result must be corroborated for court acceptance. Samples suggesting a positive outcome in Screening necessitate further confirmation.

Upon a presumptive positive result in Screening, additional hair is extracted from the original sample for the Extraction stage. In Extraction, drugs are isolated from hair at concentrations significantly lower than those in other methods (e.g., urine or oral fluid), thus making hair drug screening the most complex testing method.

Confirmation of a positive screen result is undertaken using GC/MS, GC/MS/MS, or LC/MS/MS protocols. All presumptive positive samples are cleansed before confirmation as necessary. The complete laboratory procedure, from Accessioning to Confirmation, is inspected in accordance with CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

  • Extended detection duration: Hair drug tests identify drug use for a term of up to 90 days, whereas urine tests have a shorter span.
  • Resistance to manipulation: Manipulating a hair drug test is quite challenging, thus enhancing the accuracy of outcomes.
  • Historical consumption pattern: It can reveal a timeline of drug consumption, not only recent usage.

Limitations:

  • Inability to detect recent use: Drugs become traceable in hair after roughly 5-7 days.
  • Expense: Hair drug tests generally incur higher costs than alternative testing methods.
  • Result variability: Factors like hair color and individual differences in hair development can influence drug metabolite concentration in hair.

Note: Although termed "hair follicle tests", the analysis actually focuses on the hair strand, excluding the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Tooleville, CA, hair follicle testing overtakes traditional urine tests by offering superior detection accuracy and reliability. Unlike urine tests, which offer a shorter detection window, hair testing can trace drug use patterns over a longer duration, providing a more comprehensive view of an individual's history. This enhanced detection capability helps employers enforce more effective drug-free workplace policies.

Employers, courts, and rehabilitation professionals recognize the benefits of hair testing for its extended detection periods and reduced likelihood of result manipulation. The non-invasive collection process adds to its appeal, ensuring a fair and equitable assessment while maintaining high standards of testing integrity.

Extended Detection Window

Hair follicle testing in Tooleville, CA, is known for its extended detection window, covering a timeframe of up to 90 days. This method enables employers to gather a comprehensive history of an individual’s substance use, revealing patterns that might not be detected by shorter-window tests. This extensive review period enhances the evaluation process, offering deeper insights into an applicant or employee's history.

Therefore, hair follicle testing serves as a valuable tool for employers who are committed to maintaining a drug-free workplace. Its capacity to detect drug use over a wider timespan than traditional tests ensures a thorough and informed decision-making process when it comes to hiring and maintaining safety protocols.

Tamper-Resistant Testing Method

The hair follicle testing method in Tooleville, CA, is renowned for being tamper-resistant, significantly minimizing the risk of sample adulteration. Due to the nature of hair samples, which are collected and tested under strict procedures, the reliability of the results is unquestionable, offering a robust solution for accurate drug detection.

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.
Yes. Hair drug testing is commonly used in court, probation, custody, and compliance matters because the collection process follows a documented chain of custody and the analysis is performed by a certified laboratory.
