Accredited Drug Testing offers thorough hair follicle drug analysis in Troy, Iowa. Need a hair drug or alcohol test? We excel in this area, with centers across the nation ready to conduct these tests. Generally, you need 1.5 to 2 inches of hair on your head or body for sampling. We can test for drugs, alcohol, or provide tailored options.

Recently, hair follicle testing has become a popular choice for drug screenings. Many workplaces, judicial systems, and addiction specialists now opt for hair tests over traditional urine tests. Employers with strict no-drug policies, courts, and individuals on surveillance find value in hair tests. Their main advantage lies in a longer detection window, generally up to 90 days, with an observed collection method that is hard to tamper with. Nonetheless, for detecting recent drug use within five days, urine tests remain the most precise method.

What it is, How it works

Hair testing has gained recognition as an effective method for identifying the use of drugs and alcohol. Hair captures a historical record of substance usage by embedding biomarkers within the fibers of the hair as it grows. When samples are collected from close to the scalp, they can provide a detection window of up to around 3 months for drugs and alcohol. The collection process for hair is straightforward, relatively resistant to tampering, and convenient for shipping.

A 1.5-inch section consisting of roughly 200 hair strands (comparable to the thickness of a #2 pencil) from near the scalp will produce 100mg of hair, the optimal amount for both screening and verification. For EtG testing, additional analyses, or tests exceeding 10 panels, a 150mg sample is suggested. It is advised to weigh the sample on a jeweler’s scale. If scalp hair cannot be obtained, an equal quantity of body hair may be used. When referencing head hair, it specifically pertains to scalp hair. Body hair includes all other types of hair (such as facial, axillary, etc.).

Process Overview

The laboratory procedures for processing a drug test result incorporate four primary phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial stage where a sample is logged into the laboratory's system. This process confirms that the sample was properly sealed and shipped, assigns a unique LAN (Laboratory Accessioning Number), and completes any missing data not provided by an electronic chain of custody system.

Screening executes an initial rapid inspection for drug abuse. While Screening is a budget-friendly option to rule out drug use for most samples, any positive findings require confirmation for legal admissibility. Samples with presumptive positive outcomes from Screening must undergo additional confirmation.

Should a sample test as presumptively positive during Screening, additional hair is extracted from the original sample to prepare for Extraction. During this phase, drugs are extracted from hair at notably lower concentrations compared to other methods (such as urine or oral fluid), which accounts for the greater challenge of performing hair drug screening.

The Confirmation stage for any positive screening results is executed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Presumptive positive samples undergo washing before confirmation if necessary. The complete lab procedure from Accessioning to Confirmation adheres to both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

  • Long detection window: Hair drug tests can identify drug usage for up to 90 days, unlike urine tests which feature a shorter detection timeframe.
  • Difficulty to cheat: Cheating a hair drug test is notably challenging, which enhances result accuracy.
  • Provides historical data: It offers a profile of drug use over an extended period, surpassing just recent usage.

Limitations:

  • Cannot detect recent use: Drugs typically take 5-7 days to become detectable in hair.
  • Cost: Hair drug tests generally incur higher costs compared to other drug test methods.
  • Variations in results: Elements such as hair color and individual hair growth rate can influence drug metabolite concentrations in hair.

Note: Although commonly referred to as "hair follicle tests," the test analyzes the hair strand instead of the follicle beneath the scalp.

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.
