Accredited Drug Testing offers comprehensive hair follicle drug assessments in South Bay Cities, CA. If a hair drug or alcohol test is needed, Accredited specializes in hair testing with centers nationwide ready to conduct hair assessments. Typically, 1.5 to 2 inches of hair on the crown or body suffices. Hair analyses can be customized for drugs, alcohol/ETG, or other needs.

Recently, drug testing methods have increasingly incorporated hair follicle testing. Employers, courts, and substance abuse experts now favor hair tests over traditional urine ones. Hair follicle testing supports employers with strict drug policies, courts, and probation cases. Key benefits include a 90-day detection window, observed sample collection, and near impossibility for cheating. Yet, the urine test remains most accurate for drug use within the past 5 days.

What it is, How it works

Hair analysis has evolved into a potent method for identifying drug and alcohol consumption. The fibers of the growing hair strand capture biomarkers, offering a comprehensive history of alcohol and drug use. When collected near the scalp, hair can provide up to a 3-month detection period for these substances. Hair is easy to collect, not easily adulterated, and straightforward to transport.

A sample of 1.5 inches consisting of around 200 hair strands (comparable to a #2 pencil's thickness) from the scalp will yield 100mg, which is an optimal amount for initial screening and confirmatory tests. For EtG add-ons or tests exceeding 10 panels, 150mg of the sample should be collected. It's advisable to weigh the sample using a jeweler’s scale. If scalp hair is inaccessible, an equivalent amount of body hair can be collected. When we mention head hair, it specifically refers to scalp hair. Body hair refers to all other types like facial or axillary hair.

Process Overview

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

Accessioning is the initial step where the sample is integrated into a laboratory's system. This step confirms that the sample was correctly sealed and shipped, assigns a LAN (Laboratory Accessioning Number) randomly, and completes any data entry not included by an electronic chain of custody.

Screening conducts an initial assessment for substances of abuse. Although it's an economical step to rule out drug use for most samples, a positive screen must be verified for court admissibility. Any samples that test presumptively positive during Screening require further confirmation.

Upon a presumptive positive result in Screening, additional hair is extracted from the original sample and prepared for Extraction. During this stage, drugs are isolated from hair at concentrations much lower than other methods like urine or oral fluid, making hair drug screening the most challenging methodology.

Confirmation for any positive result from Screening is performed using GC/MS, GC/MS/MS, or LC/MS/MS. Needed presumptive positive samples are cleansed before confirmation. The complete laboratory process from Accessioning to Confirmation is evaluated under the CAP (College of American Pathologists) Hair designation and conforms to ISO / IEC 17025 standards.

Advantages of hair drug testing:

  • Extended detection period: Hair testing can identify drug use for up to 90 days, whereas urine tests possess a much shorter detection timeframe.
  • Difficulty in cheating: Cheating a hair drug test is extremely challenging, ensuring more reliable results.
  • Historical usage data: Hair tests can offer an overview of drug use patterns over time, beyond just recent usage.

Limitations:

  • Recent use detection: Drugs typically take 5-7 days to become detectable in hair.
  • Expense: Generally, hair drug tests are more costly than alternative drug testing methods.
  • Result variations: Variables like hair color and individual growth rates may influence the levels of drug metabolites present in hair.

Note: These tests, frequently termed "hair follicle tests", actually analyze the hair strand above the scalp and not the follicle beneath it.

Why Hair Follicle Testing Beats Urine Testing

In the realm of drug testing, hair follicle tests in South Bay Cities, CA dramatically outperform urine tests. Hair tests offer a level of accuracy and reliability that traditional urine tests can't match. With their extended detection window, hair analyses capture substance use over months, whereas urine tests provide a snapshot of days. The methodology employed in hair testing circumvents common tricks that might skew urine test results. For employers and legal professionals, the clear choice is hair testing for dependable substance use evaluation.

Extended Detection Window

Among the many advantages of hair follicle testing in South Bay Cities, CA is its extended detection window. This method allows employers to track drug use up to 90 days prior, offering a comprehensive substance profile.

Tamper-Resistant Testing Method

One significant benefit of hair follicle testing in South Bay Cities, CA is its resistance to tampering. Unlike urine tests, which can be manipulated through numerous methods, hair tests present more reliable results. The chance to adulterate or substitute hair samples is nearly non-existent.

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.
