In 1949, the City of Alexandria began to draw its drinking water from the Occoquan Reservoir. A year later, Colonel Joseph Barger and Associates purchased the reservoir, dam, and 680 adjacent acres of land for $1 million from the Alexandria Water Company. A year later, Barger and Associates began developing the 680 acres (2.8 km2) into a residential community. During the early 1950s, residents formed a homeowners association called the Lake Barcroft Community Association (LABARCA). In 1970, community residents purchased the lake, dam, and common grounds for $300,000, and established the Barcroft Lake Management Association (BARLAMA).

Urine drug testing is the most common and customizable screening method available in the drug testing world. Many times, drug tests are ordered from companies, courts, or individuals without knowing what drug panel is needing to be analyzed.

The most common drug panel options include the 5,10, 12, 14 and 17 panel drug tests but we also offer specialized and customized panels based on your specific need and we are here to discuss exactly what is tested in each type of drug test panel.

Urine or Hair Drug Testing in Lake Barcroft, VA - You Choose!

The detection period for a urine drug test is 1-5 days. However, hair drug testing is becoming more common because the detection period for a standard hair test can be up to 90 days. You must have at least an inch and a half of hair (1.5 inches) on your head or body hair may be used when conducting a hair drug test.

Facts About 10 Panel Drug Test

  • The most cost-effective option in the workplace
  • Most common and customizable screening method
  • Detects recent drug use
  • Available in instant or lab based testing options

Remember that many opioid addictions lead to further drug use, including heroin, so you may find that a standard 5 and 10 panel is not fulfilling your needs. In this case, consider a 12-panel drug test, which tests for additional opiates and painkillers that would not show up on a test with fewer panels.

A urine drug test detects recent drug use and is currently the only testing method that is approved for federally mandated drug testing.(5 panel DOT drug Test) Urine testing is appropriate for all testing reasons, from pre-employment to random to post-accident - and can be performed for a wide range of illicit and prescription drugs.

What drug are tested for in a 10 Panel Drug Test?

The drugs tested in a10 panel urine drug test include:

  • Amphetamines
  • Barbiturates
  • Benzodiazepines
  • Cocaine
  • Marijuana
  • MDA
  • Methadone
  • Methaqualone
  • Opiates
  • PCP
  • Propoxyphene

The standard 10 panel drug test is typically collected at a collection site and analyzed at a SAMHSA Certified Laboratory. If you need a rapid results test, the 10 panel is available for a rapid result in most areas Nationwide. Results for a rapid results test are typically available the same business day (for negative results) and if a non-negative result exist, we send the specimen to the lab to perform confirmation testing at no additional charge.

What is a drug test?

A drug test is a technical analysis of a biological specimen such as urine, hair, blood, breath, finger nail and oral fluid/saliva. The common procedure for a drug test is to have a donor provide a specimen to a drug testing collection specialist, complete a chain of custody form and then the collector will send by carrier the specimen to a laboratory for analysis and a determination if the specimen is negative or positive. Although there many laboratories in the United States which provide drug testing analysis, it is recommended that only a laboratory that is SAMHSA Certified is to be used when determining a drug testing result.

Does passive smoke inhalation cause a false positive for marijuana?

"Passive" smoke inhalation from being in a room with people smoking marijuana is not considered valid, as the cut-off concentrations for lab analysis are set well above that which might occur for passive inhalation.

Other abnormalities in the urine screen may indicate that results may be a false negative or that there was deliberate adulteration of the sample. For example:

  • a low creatinine lab value can indicate that a urine sample was tampered with; either the subject diluted their urine by consuming excessive water just prior to testing, or water was added to the urine sample.
  • creatinine levels are often used in conjunction with specific gravity to determine if samples have been diluted. To help avoid this problem, the testing lab may color the water in their toilet blue to prevent the sample being diluted with water from the toilet.
  • subjects may also attempt to add certain enzymes to the urine sample to affect stability, but this often changes the pH, which is also tested.

How long do drugs stay in your system?

The window of detection or often times referred to as look back period of a drug test depend on several factors. Some of the factors impacting how long a drug will stay in your system are:

  • The amount of the drug taken
  • The frequency of the drug taken
  • The type of drug taken
  • An individual's body metabolic rate and general health
  • The amount of fluids consumed since ingesting the drug
  • The amount of exercise since ingesting the drug
  • Other genetic variations that would impact an individual's response to a specific drug

In the case of life-threatening symptoms, unconsciousness, or bizarre behavior in an emergency situation, screening for common drugs and toxins may help find the cause, called a toxicology test or tox screen to denote the broader area of possible substances beyond just self-administered drugs. These tests can also be done post-mortem during an autopsy in cases where a death was not expected. The test is usually done within 96 h (4 days) after the desire for the test is realized. Both a urine sample and a blood sample may be tested.

Local Lake Barcroft Information

Local Area Info: Lake Barcroft, Virginia

Lake Barcroft is a census-designated place (CDP) in Fairfax County, Virginia, United States. The population was 9,558 at the 2010 census. It is also the name of the privately owned lake—part of the Cameron Run Watershed—around which this population is located. The lake is named for Dr. John W. Barcroft, who owned and operated a mill on Holmes Run during the mid-19th century.

In 1913, the Alexandria Water Company began construction of the Lake Barcroft Dam on Holmes Run to create a drinking water reservoir for the city of Alexandria. Construction of the dam was completed in 1915, putting a 620 million-gallon reservoir into service. In 1942, the company installed 24 gates at the top of the dam to raise the spillway elevation five feet, increasing the reservoir size to 800 million gallons.

In 1949, the City of Alexandria began to draw its drinking water from the Occoquan Reservoir. A year later, Colonel Joseph Barger and Associates purchased the reservoir, dam, and 680 adjacent acres of land for $1 million from the Alexandria Water Company. A year later, Barger and Associates began developing the 680 acres (2.8 km2) into a residential community. During the early 1950s, residents formed a homeowners association called the Lake Barcroft Community Association (LABARCA). In 1970, community residents purchased the lake, dam, and common grounds for $300,000, and established the Barcroft Lake Management Association (BARLAMA).
