Accredited Drug Testing offers comprehensive hair follicle testing throughout San Marino, California. Whether you're in need of a hair drug or alcohol test, our specialty lies in hair testing with centers across the nation ready to assist. Typically, 1.5 to 2 inches of hair, either from the scalp or body, is required. Hair testing can detect drugs, alcohol/ETG, and other specific options to fit your needs.

Recently, the preference for drug testing has increasingly shifted toward hair follicle tests. Employers, courts, and substance abuse experts now often opt for hair over urine tests. Hair tests are chosen by those with zero-tolerance drug policies, judiciary orders, and probation conditions due to their extended detection window, reaching up to 90 days. It’s hard to tamper with, offering a more secure collection. However, for recent drug use within 5 days, urinalysis remains the go-to method.

What it is, How it works

Hair analysis has become recognized as a potent method for identifying drug and alcohol consumption. The hair strand captures long-term evidence of substance use by sequestering biomarkers within its expanding structure. When sourced near the scalp, hair offers up to a roughly 3-month timeframe for detecting substances. Collection of hair is straightforward, moderately resistant to tampering, and simple to transport.

A sample measuring 1.5 inches, encompassing around 200 strands of hair (approximately the width of a #2 pencil), closest to the scalp, provides 100mg, which is ideal for both screening and confirmation. For expanded panels like EtG and tests surpassing 10 panels, 150mg is advisable. We suggest utilizing a jeweler's scale for precision in weighing the specimen. If scalp hair is inaccessible, equivalent body hair may be retrieved. When discussing head hair, we mean scalp hair specifically. Body hair encompasses all other hair types (facial, axillary, etc.).

Process Overview

The laboratory process for drug test results involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning includes the initial integration of a specimen into a lab system. This stage ensures the sample's seal and shipment were intact, attaches a random Laboratory Accessioning Number (LAN), and fills any informational gaps not covered by an electronic chain of custody.

Screening is a preliminary check for substances of abuse. Although Screening is an economical way to exclude drug use in most specimens, a positive screen must be verified to be legally accepted. Samples that indicate a positive result in Screening necessitate further confirmation.

If screening results indicate a positive finding, additional hair is extracted from the original specimen and readied for Extraction. Drugs from hair are extracted at significantly lower levels than in other testing methods (e.g., urine or oral fluid), which makes hair drug testing the most challenging methodology to execute.

Confirmation of any positive screenings is performed using GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, all presumptive positive samples are cleaned as required. The complete process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair criteria and accredited to ISO / IEC 17025 standards.

Advantages of hair drug testing:

  • Extended detection period: Hair testing identifies drug use for up to 90 days, as opposed to urine testing, which has a restricted detection timeframe.
  • Hard to manipulate: Tampering with a hair drug test is quite challenging, enhancing result accuracy.
  • Offers usage history: Displays patterns of prolonged drug use, not just current consumption.

Limitations:

  • Inability to identify recent consumption: Drugs become detectable in hair after approximately 5-7 days.
  • Expense: Hair drug assessments generally incur higher costs than alternative testing methods.
  • Result variability: Elements like hair color and personal differences in hair growth can influence drug metabolite concentrations in hair.

Note: Often dubbed as "hair follicle tests", the examination actually involves the hair strand, excluding the scalp's hair follicle.

Why Hair Follicle Testing Beats Urine Testing

When comparing hair follicle testing to traditional urine testing, hair testing prevails due to its superior detection abilities. In San Marino, CA, hair tests offer a wider detection window, allowing employers to ascertain a more accurate picture of an individual’s drug history. This reliability makes it a preferable choice over urine testing, which may not capture intermittent drug use effectively.

Hair testing is uniquely advantageous in its ability to detect drug use over extended periods, unlike urine tests that offer a shorter detection span. Given this extended reach, it gives employers and authorities better insight into an individual’s substance use behavior, reinforcing the relevancy of hair testing in various professional and legal contexts.

Extended Detection Window

In San Marino, CA, a significant advantage of hair follicle testing is its extended detection period that spans up to 90 days. This allows employers a far-reaching insight into an individual's substance use history. This comprehensive understanding of someone’s drug use behavior aids in maintaining a safer and more responsible workplace environment.

The ability to detect substance use over a broad timeframe provides a deeper look into an applicant or employee’s historical interaction with drugs. This extensive detection is crucial for companies prioritizing thorough screening processes to support a drug-free organizational culture.

Tamper-Resistant Testing Method

Hair follicle testing in San Marino, CA, is celebrated for being tamper-resistant, significantly decreasing the threat of sample adulteration. Given its collection method, it's challenging to manipulate, ensuring that results remain credible and unchallenged. This reliability is why many organizations and judicial entities prefer hair testing over others.

The method's inherent resistance to tampering elevates its importance in drug screening programs. By minimizing the risk of contamination or deception, hair follicle testing maintains a standard of accuracy that reinforces trust in the testing process and outcomes.

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.
