Accredited Drug Testing offers comprehensive hair follicle drug assessments in Portola, California. If you're in need of a hair drug or alcohol evaluation, Accredited Drug Testing excels in this area with testing sites across all cities nationwide ready to conduct a hair analysis. Typically, 1.5 to 2 inches of hair from your head or body is required for testing. Hair analyses can detect drugs, alcohol/ETG, or tailor to other unique hair testing needs.

Over the past few years, the use of hair follicle drug evaluations has become more prevalent. Employers, courts, and substance abuse experts are opting for hair drug analyses over customary urine tests. Employers enforcing strict drug-free policies, courts, and probationary programs prefer hair follicle tests for their extended detection, which often spans up to 90 days and undergoes direct collection, making them hard to falsify. Urine tests, however, remain most precise for identifying very recent drug use within a five-day timeframe.

What it is, How it works

Hair assessments are increasingly recognized as an effective means for identifying drug and alcohol consumption. Hair encapsulates a prolonged record of substance use by embedding biomarkers within the fibers of the hair strand as it grows. When clipped near the scalp, hair can reveal up to a roughly 3-month timeline for detecting alcohol and drugs. Hair is straightforward to gather, quite hard to tamper with, and effortless to transport.

A 1.5-inch section consisting of about 200 hair strands (comparable to the size of a #2 pencil) nearest to the scalp yields 100mg of hair, which is the optimal amount for analysis and confirmation. For EtG, additional tests, and/or examinations exceeding 10 panels, a 150mg sample is advised. Using a jeweler’s scale to weigh the sample is suggested. If scalp hair is not available, a similar quantity of body hair may be used. When specifying head hair, we mean scalp hair only. Body hair encompasses all other types (facial, axillary, etc.).

Process Overview

The drug testing process in the lab includes four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial phase where a sample is entered into the lab’s system. This step involves verifying the sample's proper sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and completing any required data entry not captured by an electronic chain of custody system.

Screening serves as a preliminary inspection for potential substances of abuse. Although Screening is a cost-efficient method to dismiss drug usage for most samples, a positive indication necessitates validation for legal proceedings. Any samples with a presumptive positive result in Screening require further confirmation.

If a sample shows a presumptive positive during Screening, additional hair is taken from the original sample and prepped for Extraction. In this process, substances are extracted from the hair at much lower concentrations than other methods (ex. urine or oral fluid), making hair drug testing one of the most challenging methods to execute.

Confirmation of any positive findings from Screening is performed using GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, any samples with presumptive positive results are cleaned as needed. The complete lab process from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and the certification to ISO / IEC 17025 standards.

Advantages of hair drug testing:

  • Extended detection period: Hair drug tests can reveal drug use for up to 90 days, compared to urine tests that have a shorter detection timeframe.
  • Challenging to falsify: Cheating a hair drug test is very difficult, thus providing more accurate outcomes.
  • Presents historical usage: It can show a pattern of substance use over time, not just short-term use.

Limitations:

  • Unable to identify recent intake: Drugs only become detectable in hair after approximately 5-7 days.
  • Expense: Hair drug tests typically cost more than other testing methods.
  • Result variability: Variables such as hair color and differences in individual hair growth can influence drug metabolite levels in hair.

Note: Although commonly called "hair follicle tests," the test actually focuses on the hair strand and not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Why Hair Follicle Testing Beats Urine Testing in Portola, CA

The superiority of hair follicle testing over traditional urine testing lies in its enhanced detection capabilities. By examining hair samples, one can identify drug usage within a longer window, often stretching back months.

Additionally, hair tests are less susceptible to tampering, providing an added layer of reliability.

The accuracy and durability of detection with hair tests make them a preferable choice for environments prioritizing precision. Where traditional urine tests may falter or present logistical challenges, hair tests stand firm. Opting for hair analysis, especially in work settings, translates to enhanced safety and policy compliance.

Frequently Asked Questions

A hair follicle drug test analyzes a small sample of hair to detect a history of drug use over time. Because drug metabolites are incorporated into hair as it grows, this method can show patterns of use instead of just recent exposure. 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. Results are provided in a form that can be reviewed by legal and administrative authorities.
Yes. Individuals, parents, attorneys, employers, and probation programs can all request hair drug testing. A doctor's order is not required. Results are confidential and released only to the authorized requesting party.
