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

AI Overview

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: Corvallis, Oregon

Corvallis /k??r?væl?s/ is a city in central western Oregon, United States. It is the county seat of Benton County and the principal city of the Corvallis, Oregon Metropolitan Statistical Area, which encompasses all of Benton County. As of the 2010 United States Census, the population was 54,462. Its population was estimated by the Portland Research Center to be 55,298 in 2013. Corvallis is the location of Oregon State University, a large Hewlett-Packard research campus, and Good Samaritan Regional Medical Center.

In October 1845, Joseph C. Avery arrived in Oregon from the east. Avery took out a land claim at the mouth of Marys River, where it flows into the Willamette River, and in June 1846 took up residence there in a log cabin hastily constructed to hold what seemed a potentially lucrative claim. Avery's primitive 1846 dwelling was the first home within the boundaries of today's Corvallis and his land claim included the southern section of the contemporary city.

Avery was quickly joined by other settlers along the banks of the Willamette River, including a 640-acre claim directly to his north taken in September 1846 by William F. Dixon. The discovery of gold in California in 1848 temporarily stalled development of a township, with Avery leaving his Oregon claim to try his hand at mining in the fall of that year. His stay proved to be brief, and in January 1849, Avery returned to Oregon with a small stock of provisions with a view to opening a store.
