Accredited Drug Testing provides comprehensive hair follicle drug tests in Green Valley Farms, Texas. For those in need of a hair drug or alcohol test, we excel in hair testing and have facilities available in every city Nationwide to conduct such tests. Typically, you need to have 1.5 to 2 inches of hair on your crown or other body areas. Hair testing can assess for drugs, alcohol/ETG, or other tailored options.

Recently, there has been a rise in using the hair follicle drug test for substance screening. Employers, courts, and Substance Abuse professionals now often opt for hair drug testing over traditional urine tests. These tests are chosen by employers with zero-tolerance policies, courts, and for individuals on probation. Hair follicle tests offer the advantage of detecting drug use over a prolonged period, up to 90 days, with nearly impossible test tampering and observation during collection. However, urine tests remain most precise for detecting recent drug use within five days.

What it is, How it works

Hair analysis has emerged as an effective method for identifying drug and alcohol consumption. Hair strands offer a comprehensive timeline of substance use by encapsulating biomarkers within the growing fiber structure. When sampled close to the scalp, hair can reflect substance use within an approximate three-month window. The simplicity of collection, resistance to tampering, and convenience of shipping make hair samples advantageous.

A 1.5-inch segment consisting of roughly 200 hair strands (comparable to the size of a #2 pencil) nearest the scalp provides approximately 100mg of hair, which is optimal for both preliminary screening and confirmation. For EtG testing, additional panels beyond 10, or special add-ons, a sample of 150mg is preferred. Utilizing a jeweler’s scale is advised for weighing the sample. If scalp hair is not available, an equivalent volume of body hair is acceptable. Note that head hair refers solely to scalp hair, whereas body hair encompasses all other types such as facial and axillary hair.

Procedure Overview

The laboratory assessment of a drug test consists of four principal steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning incorporates initial sample handling within laboratory systems, ensuring the sample's integrity in terms of proper sealing and shipping, assigning a unique LAN (Laboratory Accessioning Number), and entering all requisite information not covered by automated custody systems.

Screening involves a preliminary evaluation for drug substances. Although cost-effective, Screening serves as a quick method to exclude drug use in most samples, a positive outcome necessitates subsequent verification to stand in legal settings. Samples indicating positive results in Screening must undergo further confirmation.

In cases where a sample shows presumptive positivity during Screening, additional hair is extracted from the initial sample for the Extraction phase. In this process, drug elements are isolated from hair, albeit at much lower concentrations compared to methods like urine or oral fluid testing, underscoring the complexity of hair drug testing procedures.

Validation of any positive screening outcomes occurs through GC/MS, GC/MS/MS, or LC/MS/MS technologies. All samples flagged as presumptive positives undergo washing before confirmation when needed. From Accessioning to Confirmation, every phase of laboratory processing is rigorously evaluated under the CAP (College of American Pathologists) Hair guidelines and ISO / IEC 17025 accreditation standards.

Benefits of hair drug testing:

  • Extended detection period: Hair drug testing can identify drug use over a span of up to 90 days, offering a more extended window than urine tests.
  • Challenging to manipulate: Due to the nature of hair drug tests, they are difficult to falsify, enhancing accuracy.
  • Historical usage insight: Provides insights into patterns of drug use over a timeline rather than merely recent occurrences.

Challenges:

  • Recent use detection: Drugs take about 5-7 days to become traceable in hair.
  • Expense: Hair drug testing typically incurs higher costs than alternative drug testing strategies.
  • Analytical variability: Differences in hair color and individual growth rates may influence drug metabolite concentrations in hair.

Note: Though commonly dubbed "hair follicle tests," the analysis targets the hair shaft, not the underlying follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

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.
