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 Professional 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 include 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

Hair Follicle Drug Testing: An Overview

Hair follicle drug testing is a method used to detect the use of illicit drugs or the misuse of prescription drugs over an extended period. Unlike urine tests, which can detect recent drug use, hair follicle testing provides a longer window of detection, typically up to 90 days. This overview explores how hair follicle drug testing works, its applications, and its benefits.

How Hair Follicle Drug Testing Works

The process involves taking a small sample of hair, usually from the head but sometimes from the body if scalp hair is insufficient. The hair is tested to identify drugs and their metabolites, which are deposited in the hair from the bloodstream. This method is sensitive to a wide range of substances, including marijuana, cocaine, opiates, methamphetamine, and phencyclidine (PCP).

Applications of Hair Follicle Drug Testing

  • Employment Screening: Many employers use hair follicle testing as part of their pre-employment screening processes and in regular checks to ensure a drug-free workplace.
  • Legal and Forensic Cases: This testing is used in legal settings to provide evidence in custody disputes, DUI cases, and other legal matters requiring proof of drug use.
  • Rehabilitation Monitoring: Health care providers and rehab centers use hair tests to monitor individuals recovering from drug addiction.

Advantages of Hair Follicle Drug Testing

  1. Long Detection Period: Can detect drug use for up to 90 days, making it more effective for identifying long-term drug use than other testing methods.
  2. Tamper Resistance: The nature of hair sample collection makes it difficult to tamper with or substitute samples, providing more accurate results.
  3. Non-invasive: The process is simple and does not require the handling of bodily fluids, making it less invasive and safer to administer.

Considerations and Limitations

While hair follicle drug testing is highly effective, there are considerations to keep in mind:

  • Growth Rate Variability: Hair growth rates can vary from person to person, potentially affecting the detection window.
  • Potential for External Contamination: Drugs can sometimes be absorbed from the environment, leading to potential false positives, though washing the hair sample prior to testing can mitigate this risk.
  • Cultural and Personal Concerns: The requirement of hair samples can raise concerns among those with hair loss or individuals whose cultural practices affect hair grooming or styling.

Hair follicle drug testing is a reliable and comprehensive method for detecting drug use over an extended period. It is widely used across various sectors for its accuracy and tamper-resistant methodology, making it a valuable tool in maintaining drug-free environments and supporting legal and medical interventions.

Local Area Info: Potomac, Maryland

Potomac (listen (help·info)) is a census-designated place (CDP) in Montgomery County, Maryland, United States, named for the nearby Potomac River. In 2013, CNNMoney listed Potomac as the most affluent town in all the United States, based on median household income. Potomac is also the seventh-most top-educated American small town according to Forbes. Bloomberg Businessweek labeled Potomac as the twenty-ninth-richest zip code in the United States in 2011, stating that it had the largest population of any U.S. town with a median income of more than $240,000. In 2012, The Higley Elite 100 published a list of highest-income neighborhoods by mean household income, which included four neighborhoods in Potomac; one of these neighborhoods, "Carderock-The Palisades" was ranked the highest-income neighborhood in the United States, followed by "Beverly Hills-North of Sunset" in Beverly Hills, California, and "Swinks Mill-Dominion Reserve" of McLean, Virginia. More recently, two Potomac neighborhoods were ranked among the ten wealthiest neighborhoods in the country by CNBC in 2014. In 2018, data from the American Community Survey revealed that Potomac was the sixth-wealthiest city in the United States. Many Potomac residents work in nearby Washington, D.C.

The land that is now Potomac Village was first settled by Edward Offutt in 1714 after he was granted a 600-acre (2.4 km2) land grant "Clewerwell" by Lord Baltimore. His grant of land was by the Tehogee Indian Trail, an Indian trade route built by the Canaze Indian nation in 1716. Throughout the 18th century, what became known as Offutts Crossroads was a small, rural community which served planters and travelers. In the 19th century, a few small dwellings had been built along with a tavern established in 1820. By the time of the Civil War, the community contained two general stores, a blacksmith shop, and a post office which served a community of 100.

Offutts Crossroads was renamed Potomac in 1881 by John McDonald. An Irishman and veteran of the Civil War, McDonald settled in Potomac around that time. He petitioned for the name change since postal officials were asking for brief names and there were already several other communities in the area with the name "crossroads".
