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.

  • Amphetamines
  • Barbiturates
  • Benzodiazepines
  • Cocaine
  • Marijuana
  • MDA
  • Methadone
  • Methaqualone

The standard 10 panel drug test is typically collected at a collection site and analyzed at a SAMHSA Certified Laboratory.

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 Colfax Information

Local Area Info: Colfax, California

Colfax (formerly, Alden Grove, Alder Grove, Illinoistown, and Upper Corral) is a city in Placer County, California, at the crossroads of Interstate 80 and State Route 174. It is part of the Sacramento–Arden-Arcade–Roseville Metropolitan Statistical Area. The population was 1,963 at the 2010 census. The town is named in honor of U.S. Vice President Schuyler Colfax (1869–73), a bronze statue of whom stands at Railroad Street and Grass Valley Street. (This is the only known statue of Schuyler Colfax in the United States). Some of the town's notable features include the newly restored Southern Pacific Railroad colonnade-style depot (which houses the Colfax Museum and Chamber of Commerce) built in 1905, the downtown shops on Main Street, and Colfax High School, which serves a large surrounding area.

Originally inhabited by the Maidu and Miwok Indians, by the mid-19th century the city site was known as Alder Grove; however, as development increased, the city became known as Illinoistown. In April 1852, the Reelfoot Williams Gang robbed a Nevada City stagecoach of $7,000 in gold bullion near Illinoistown. This was the first stagecoach robbery in the gold country.

Later it was renamed Colfax after then Speaker of the House (and later Vice President) Schuyler Colfax who visited the town in 1865 while inspecting progress of construction of the Central Pacific Railroad, the western portion of the first transcontinental railroad. The city was the southern terminus of the Nevada County Narrow Gauge Railroad from 1876 until the railroad’s removal in 1942. Historic U.S. Route 40 also runs through the city as well as the more modern Interstate 80. The city is mentioned in Jules Verne’s book, Around the World in Eighty Days.
