Hair Follicle Drug Test

In recent years the method to conduct drug testing has more frequently included a hair follicle drug test. Many employers, courts and Substance Abuse Professionals are requiring a hair follicle drug test instead of a standard urine test. Hair follicle drug tests are used by employers who have zero-tolerance drug use policies, courts and individuals on probation. The primary benefit of a hair follicle drug test includes a much longer detection period for drug use which typically is up to 90 days. However, when screening drug use within the last 5 days the urine test continues to be the most accurate test.

Hair Follicle Drug Test Process

The procedure used to perform a hair follicle test is simple, the drug testing specialist will cut approximately 120 strands of hair (not really a lot) utilize a chain of custody procedure and send the hair to a certified laboratory for analysis. Drug testing centers require at least 1.5 inches of hair to perform this test and the hair generally needs to come from the head, however if the donor does not have head hair certain testing centers can use hair from chest, leg or arm pit.

If a donor has no hair on their body, than a hair test cannot be performed!

Hair Follicle Drug Test Results

Once the hair follicles have been analyzed by a certified laboratory they will then be reviewed and then verified by a Medical Review Officer (licensed Physician) who will than release the results. Generally a negative hair follicle drug test result is available in 2-3 days. A non-negative hair follicle drug test is available in approximately 5 days.

Urine cut-off levels are expressed in nanograms per milliliter (ng/mL) or as a weight of drug per unit volume of urine. Hair cut-off levels are expressed in picograms per milligram (pg/mg) or as a weight of drug per unit weight of hair

AI Overview

Comprehensive Guide to Hair Follicle Drug Testing

Hair follicle drug testing is a sophisticated technique used to detect both illicit drug use and the misuse of prescription drugs over an extended period. This method of testing is favored for its ability to provide a detailed drug use history far beyond the capability of standard urine tests, which only capture drug use within days of consumption.

Understanding Hair Follicle Drug Testing

During a hair follicle drug test, a small sample of hair is collected, usually from the head. This sample is then analyzed to detect drug molecules and their metabolites that have been deposited into the hair from the bloodstream. Drugs that can be detected include but are not limited to cannabis, cocaine, opiates, and methamphetamine.

Key Applications

  • Workplace Compliance: Employers often implement hair follicle testing to maintain a drug-free work environment, especially in industries where safety is paramount.
  • Legal Evidence: In the legal arena, these tests can provide compelling evidence in cases such as custody disputes or driving under the influence (DUI) incidents.
  • Substance Abuse Monitoring: Rehabilitation centers may utilize hair tests to monitor individuals over time, ensuring adherence to treatment programs.

Benefits of Hair Follicle Drug Testing

  1. Extended Window of Detection: Unlike other tests, hair follicle testing can detect drug use up to 90 days back, offering a long-range view into an individual's drug history.
  2. Low Risk of Tampering: Since hair samples are collected directly and observed, the risk of sample tampering is significantly reduced compared to other forms of testing.
  3. Less Invasive: Collecting hair is far less intrusive compared to blood tests, making it more comfortable for the individual being tested.

Limitations to Consider

Despite its advantages, hair follicle testing isn't without its challenges:

  • Rate of Hair Growth: Variations in hair growth rates can affect the detection period, slightly complicating the interpretation of results.
  • Environmental Contamination: In rare cases, drugs can be externally deposited onto the hair, although rigorous washing protocols before testing help mitigate this issue.
  • Cultural Sensitivity: The need for a hair sample can pose dilemmas for individuals with cultural or religious practices affecting their hair.

Hair follicle drug testing stands out as a reliable method for analyzing long-term drug use. Its application spans various fields from corporate environments to legal settings, making it an indispensable tool for ensuring safety and compliance with drug policies.

Local Area Info: Knoxville, Tennessee

Knoxville is a city in the U.S. state of Tennessee, and the county seat of Knox County. The city had an estimated population of 186,239 in 2016 and a population of 178,874 as of the 2010 census, making it the state's third largest city after Nashville and Memphis. Knoxville is the principal city of the Knoxville Metropolitan Statistical Area, which, in 2016, was 868,546, up 0.9 percent, or 7,377 people, from to 2015. The KMSA is, in turn, the central component of the Knoxville-Sevierville-La Follette Combined Statistical Area, which, in 2013, had a population of 1,096,961.

First settled in 1786, Knoxville was the first capital of Tennessee. The city struggled with geographic isolation throughout the early 19th century. The arrival of the railroad in 1855 led to an economic boom. During the Civil War, the city was bitterly divided over the secession issue, and was occupied alternately by both Confederate and Union armies. Following the war, Knoxville grew rapidly as a major wholesaling and manufacturing center. The city's economy stagnated after the 1920's as the manufacturing sector collapsed, the downtown area declined and city leaders became entrenched in highly partisan political fights. Hosting the 1982 World's Fair helped reinvigorate the city, and revitalization initiatives by city leaders and private developers have had major successes in spurring growth in the city, especially the downtown area.

Knoxville is the home of the flagship campus of the University of Tennessee, whose sports teams, called the "Volunteers" or "Vols", are extremely popular in the surrounding area. Knoxville is also home to the headquarters of the Tennessee Valley Authority, the Tennessee Supreme Court's courthouse for East Tennessee and the corporate headquarters of several national and regional companies. As one of the largest cities in the Appalachian region, Knoxville has positioned itself in recent years as a repository of Appalachian culture and is one of the gateways to the Great Smoky Mountains National Park.
