In Eureka, California, Accredited Drug Testing provides comprehensive hair follicle drug testing services. For individuals needing a hair drug or alcohol test, Accredited Drug Testing excels in hair testing with centers across the nation ready to conduct a hair test. Generally, you'll need 1.5 to 2 inches of hair, often taken from the crown or body. Hair tests can detect drugs, alcohol/ETG, and more tailored options.

Lately, drug testing has increasingly involved hair follicle tests. Many employers, legal systems, and substance abuse experts prefer hair tests over the typical urine test. Employers with zero-tolerance policies, courts, and probationers utilize these tests. The main advantage of hair follicle tests is a notably longer drug use detection window of up to 90 days, conducted under strict observation, making cheating nearly impossible, though urine tests still lead in recent usage detection within five days.

What it is, How it works

Hair examination has evolved into a valuable instrument for identifying drug and alcohol consumption. Hair offers a prolonged history of alcohol and other substances by capturing biomarkers within the fibers of the developing hair strand. When gathered close to the scalp, hair can present up to roughly a 3-month observation period for alcohol and other drugs. Hair is straightforward to gather, rather difficult to tamper with, and simple to send.

A 1.5-inch portion of approximately 200 hairs (comparable to the size of a #2 pencil) nearest the scalp will yield 100mg of hair, the ideal amount for analysis and verification. For EtG, add-ons, and/or examinations beyond 10 panels, 150mg of the specimen is advised. We suggest weighing the specimen with a jeweler’s scale. If scalp hair is unavailable, an equivalent amount of body hair can be gathered. When mentioning head hair, we mean only scalp hair. Body hair includes all other hair types (facial, axillary, etc.).

Process Overview

The four primary stages in the laboratory handling of a drug test result are Accessioning, Screening, Extraction, and Confirmation.

Accessioning encompasses the initial introduction of a sample into a laboratory’s system. This entails ensuring that the sample was sealed and transported correctly, assigning a random LAN (Laboratory Accessioning Number), and performing any further data entry not supplied by an electronic chain of custody system.

Screening involves a preliminary rapid assessment for drugs of abuse. While Screening is a cost-efficient technique to eliminate drug usage in the bulk of samples, a positive screen must be confirmed to be admissible in court. Any samples that are initially positive in Screening necessitate a subsequent confirmation.

If a specimen is initially positive in the Screening phase, additional hair is taken from the primary specimen and prepared for Extraction. In this phase, drugs are extracted from hair at a significantly lower concentration than in alternative methodologies (e.g., urine or oral fluid), which is why hair drug examination is the most challenging methodology to perform.

Verification of any positive initial screening result is conducted via GC/MS, GC/MS/MS or LC/MS/MS. All initially positive samples are cleansed before confirmation as necessary. The complete laboratory process from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Benefits of hair drug testing:

  • Extended detection period: Hair drug tests can reveal drug use for up to 90 days, unlike urine tests which have a shorter detection period.
  • Challenging to deceive: It is extremely difficult to deceive a hair drug test, leading to more accurate outcomes.
  • Supplies historical trends: It offers a record of drug use over a time frame, not just recent use.

Drawbacks:

  • Cannot identify recent use: It takes approximately 5-7 days for drugs to be noticeable in hair.
  • Expense: Hair drug tests are generally costlier than other drug examination methods.
  • Variability in outcomes: Elements such as hair color and individual variations in hair growth can impact the concentration of drug metabolites in the hair.

Note: Although often called "hair follicle tests", the examination itself analyzes the hair strand and not the hair follicle beneath the scalp

Why Hair Follicle Testing Beats Urine Testing

Why Hair Testing Outperforms Urine Tests in Eureka, CA
Comparing hair and urine tests, hair follicle testing stands out due to its longer detection period. While urine tests only catch recent usage, hair tests detect drug use up to 90 days back, providing a more thorough overview of an individual's substance history. This longer window is crucial for employers and legal systems aiming for a drug-free environment.

The high detection accuracy makes hair testing preferable for many in Eureka. Unlike urine tests, hair tests are less susceptible to manipulation and provide consistent, reliable results. Employers value the clarity provided by hair tests, bolstering trust and accuracy in evaluating candidates or current employees over traditional methods.

Extended Detection Window

Hair follicle testing offers an extended detection window in Eureka, CA, reaching up to 90 days. This capability provides employers with a comprehensive view of an individual's drug history, essential for informed decision-making. Unlike other tests, the long detection period allows better assessment of consistent substance usage, ensuring a more reliable and thorough evaluation.

The extensive detection period of hair follicle testing benefits organizations aiming to maintain clean workplace practices. It not only captures drug use history but enhances screening efficiency by covering more extended periods, thus aiding in monitoring employee adherence to workplace policies. This makes hair testing an invaluable tool for retaining high workplace standards.

Tamper-Resistant Testing Method

In Eureka, CA, hair follicle tests significantly decrease the risk of sample tampering. Unlike other testing methods, hair samples are resilient to common cheating techniques, providing results that stakeholders can trust.

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.
