During September 1, Pope, apprised of Jackson's movement, began to withdraw toward Fairfax Court House. Late in the day, Jackson clashed with Union forces under Brigadier General Isaac Stevens and Major General Philip Kearny near Ox Hill, west of Fairfax. During the ensuing battle, which was fought amid a raging storm, both Union generals Stevens and Kearny were killed. The fighting ended at dusk, and Pope's army continued its withdrawal to Fairfax and subsequently to the Washington defenses.

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.

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: Chantilly, Virginia

Chantilly is a census-designated place (CDP) in western Fairfax County, Virginia, United States. The population was 23,039 at the 2010 census. Chantilly is named after an early-19th-century mansion and farm, which in turn took the name of an 18th-century plantation that was located in Westmoreland County, Virginia. The name "Chantilly" originated in France with the Château de Chantilly, about 25 miles north of Paris.

Located in the Northern Virginia portion of the Washington metropolitan area, Chantilly sits approximately 25 miles (40 km) west of Washington, D.C., via Interstate 66 and U.S. Route 50. It is located between Centreville to the south, Herndon and Reston to the north and northeast, respectively, and Fairfax 7 miles (11 km) to the southeast. U.S. Route 50 and Virginia State Route 28 intersect in Chantilly, and these highways provide access to the Dulles/Reston/Tysons Corner technology corridor and other major employment centers in Northern Virginia and Washington, D.C.

Chantilly was home to a number of colonial plantations in the 1700s, including the Sully Plantation (now the Sully Historic Site) built by Richard Bland Lee I. Other plantations included George Richard Lee Turberville's "Leeton Grove" (originally a 5,000+ acre plantation, the main house of which still stands at 4619 Walney Rd.), the John Hutchison Farm, and the Chantilly Plantation, after which Chantilly is named. Cornelia Lee Turberville Stuart, who was born at Leeton and was the daughter of George Richard Lee Turberville and Henrietta Lee, inherited a portion of Leeton in 1817 from her father. Stuart and her husband Charles Calvert Stuart, whom she had married in 1816, constructed the Chantilly Plantation and named it after the Westmoreland County plantation owned by her grandfather, Richard Henry Lee, a signer of the Declaration of Independence. During the Civil War, federal troops destroyed by fire the Chantilly Plantation manor house. One building remains, a stone house across Route 50 from the Greenbriar Shopping Center. While it is not clear what this stone house was used for, most historical evidence suggests it was probably a plantation overseer's quarters during the antebellum period, and a tavern or boarding house following the war. After the war, Cornelia Stuart, who had become deeply in debt, sold her 1,064-acre (431 ha) Chantilly estate. The advertisement for the sale referenced several "tenements", one of which was the Stone House.

During September 1, Pope, apprised of Jackson's movement, began to withdraw toward Fairfax Court House. Late in the day, Jackson clashed with Union forces under Brigadier General Isaac Stevens and Major General Philip Kearny near Ox Hill, west of Fairfax. During the ensuing battle, which was fought amid a raging storm, both Union generals Stevens and Kearny were killed. The fighting ended at dusk, and Pope's army continued its withdrawal to Fairfax and subsequently to the Washington defenses.
