Accredited Drug Testing offers thorough hair follicle drug examinations in Visalia, California. Should you require testing for drugs or alcohol using hair samples, Accredited Drug Testing offers specialization in this method, with facilities present across all cities nationwide to conduct hair tests. Generally, 1.5 to 2 inches of hair from your head's crown is necessary; alternatively, body hair may be employed. Hair tests can detect drugs, alcohol/ETG, or offer tailored testing options.

Recently, the approach to drug screening has increasingly incorporated hair follicle drug tests. An increasing number of employers, judicial systems, and Substance Abuse experts are opting for hair drug tests over traditional urine exams. Hair drug tests are employed by employers maintaining stringent no-drug policies, the judiciary, and individuals under probation. Their major advantage lies in the prolonged detection timeframe for drug usage, up to 90 days, with observation during sample collection, and they are nearly uncheatable. Yet, for recent substance use detection within five days, urine tests remain the more definitive option.

What it is, How it works

Hair analysis is now recognized as an effective method for identifying drug and alcohol consumption. Hair captures a historical record of substance use by sequestering biomarkers within the fibers of the growing hair shaft. When collected near the root, hair can reveal an approximately 3-month detection period for alcohol and drugs. Hair is easy to gather, challenging to tamper with, and simple to transport.

A 1.5-inch segment of roughly 200 hairs (comparable to a #2 pencil) nearest to the scalp will yield 100mg of hair, ideal for both screening and validation. For EtG, add-ons, and/or tests exceeding 10 panels, 150mg of the sample is advised. We suggest using a jeweler’s scale to measure the sample. If scalp hair is not accessible, a comparable amount of body hair can be harnessed. In referencing head hair, we denote scalp hair solely. Body hair encompasses all other varieties (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result comprises four key stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial sample induction into a laboratory's database. This includes validating that the specimen was intact and shipped correctly, assigning a random LAN (Laboratory Accessioning Number), and executing any further data input not covered by an electronic custody system.

Screening constitutes a preliminary rapid assessment for illicit substances. While cost-efficient for excluding drug use in most samples, a positive screen must be corroborated to be legally tenable. Any presumptive positives in Screening necessitate a subsequent confirmation.

In the event of a presumptive positive at the Screening phase, additional hair is extracted from the primary sample and readied for Extraction. At this juncture, drugs are retrieved from hair at notably lower concentrations than other techniques (e.g., urine or saliva), underscoring why hair drug testing is the most complex methodology to execute.

Confirmation of any positive screen occurs via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are laundered as required before confirmation. The comprehensive laboratory workflow from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

  • Extended detection period: Hair drug screening can identify drug use for up to 90 days, unlike urine tests with a shorter detection timeframe.
  • Hard to manipulate: Hair drug tests are difficult to circumvent, ensuring more reliable results.
  • Supplies historical insight: It can elucidate a pattern of drug consumption over a duration, not merely recent usage.

Limitations:

  • Incapable of detecting recent use: It requires approximately 5-7 days before drugs become traceable in hair.
  • Expense: Hair drug tests typically cost more than other drug assessment techniques.
  • Result variability: Factors like hair pigmentation and individual hair growth discrepancies can influence drug metabolite concentrations in the hair.

Note: Although commonly termed "hair follicle tests", the assessment actually inspects the hair shaft and not the follicle beneath the scalp

Why Hair Follicle Testing Beats Urine Testing

In Visalia, CA, hair follicle tests are superior to traditional urine tests due to their longer detection period. Unlike urine tests, which are limited to detecting drugs used within a few days, hair testing extends this window up to 90 days, providing a more comprehensive drug use history.

The accuracy of hair follicle tests surpasses that of urine tests. This makes them an ideal choice for employers with strict non-drug policies who demand reliability. Besides, while urine samples could be tampered with, hair samples offer a more foolproof option, ensuring authenticity.

Extended Detection Window

Hair follicle testing in Visalia, CA offers an unprecedented detection window, reaching up to 90 days into the past. For employers, this means a chance to gather complete insights into an individual's substance use over an extended period, enabling more informed hiring decisions.

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.
