Accredited Drug Testing offers thorough hair follicle drug testing services in Hamilton City, California. If you're in need of a hair drug or alcohol test, our specialty is hair testing, with testing centers available nationwide, including all cities. Typically, 1.5 to 2 inches of hair from the head or body is required. Tests can detect drugs, alcohol/ETG, or be customized for other hair testing options.

Recently, the use of hair follicle drug tests has become more prevalent. Employers, courts, and Substance Abuse professionals often choose hair drug tests over the traditional urine method. Hair follicle tests benefit employers with zero-tolerance policies, courts, and probation scenarios due to their longer detection period of up to 90 days, observed collection process, and resistance to tampering. However, urine tests remain more accurate for detecting drug use within the last 5 days.

What it is, How it works

Hair testing is now regarded as an effective means to uncover drug and alcohol consumption. The hair locks in biomarkers along its strands, offering a comprehensive record of substance intake over time. When taken from near the scalp, a hair sample can indicate the presence of alcohol and drugs over a period extending up to three months. Its collection is straightforward, resistant to tampering, and can be easily dispatched.

A hair sample measuring 1.5 inches, comprising around 200 strands (akin to a #2 pencil size), yields about 100mg, which is optimal for both screening and confirmation. If testing for EtG, additional substances, or exceeding 10 panels, a sample weighing 150mg is suggested. Using a jeweler's scale for weighing is advised. In the absence of scalp hair, a comparable body hair sample may be used. 'Head hair' exclusively refers to scalp hair, while 'body hair' encompasses all other types (facial, axillary, etc.).

Process Overview

The laboratory processes a drug test through four essential stages: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, the sample initiates processing into the lab's system, entailing verification of proper sealing and shipment, assigning a random LAN (Laboratory Accessioning Number), and inputting any data not covered by an electronic custody chain.

Screening acts as a preliminary scan for substance abuse, offering a budget-friendly method to eliminate drug use in most cases. However, a positive result requires confirmation for legal credibility, necessitating further analysis on samples indicated as preliminary positives.

Presumptively positive samples during Screening are subjected to further hair extraction from the original sample, prepared for Extraction. Here, substances are retrieved from the hair at much lower levels than other tests (like urine or oral fluid), which makes hair drug testing a challenging process.

Confirmatory analysis for any positive screen is executed using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positives are cleaned before confirmation when necessary. The full lab procedure, from Accessioning to Confirmation, is assessed under both CAP (College of American Pathologists) Hair guidelines and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

  • Extended detection period: Hair drug screening can highlight drug consumption for up to 90 days, whereas urine tests trace a shorter timeframe.
  • High integrity: Manipulating hair drug tests is quite challenging, ensuring more precise outcomes.
  • Chronological usage data: Offers insights into a longer drug usage timeline beyond recent consumption.

Limitations:

  • Recent use detection issues: It typically takes 5-7 days for drugs to become traceable in hair.
  • Expense: Hair drug assessments are usually costlier than other testing methods.
  • Result variability: Hair color and individual growth rates can influence drug metabolite levels.

Note: Commonly called "hair follicle tests", the examination focuses on analyzing the hair strand, excluding the follicle beneath the scalp.

What's New In Hair Follicle Drug Testing according to the Hair Drug Testing Experts

With its multidisciplinary nature, hair testing brings together researchers, scientists, and experts from various domains to develop innovative techniques, explore new methodologies, and address emerging concerns, responding to the ever-evolving challenges of drug abuse, therapeutic drug monitoring, and environmental exposures to pollutants.

The joint meeting of the Society of Hair Testing (SoHT) and the Italian Group of Forensic Toxicologists (GTFI) was organized in Verona, June 8–10, 2022, and hosted by the Legal Medicine team of the Verona University Hospital, directed by Franco Tagliaro together with Federica Bortolotti and Rossella Gottardo.

It served as a prominent platform for knowledge exchange and collaboration, facilitating groundbreaking advancements in hair testing and analysis. In this special issue of Drug Testing and Analysis, we aim to showcase the remarkable manuscripts presented at this significant event, shedding light on the latest research and highlighting the future directions in this field.

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.
