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 Whittier, CA - 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 Whittier Information
Local Area Info: Whittier, California
Whittier is a city in Southern California located within Los Angeles County, California. As of the 2010 United States Census, the city had a population of 85,331, reflecting an increase of 1,631 from the 83,680 counted in the 2000 Census, and encompasses 14.7 square miles (38.0 km2). Like nearby Montebello, the city constitutes part of the Gateway Cities. Whittier was incorporated in February 1898 and became a charter city in 1955. The city is named for the poet John Greenleaf Whittier and is home to Whittier College.
Whittier's roots can be traced to Spanish soldier Manuel Nieto. In 1784, Nieto received a Spanish land grant of 300,000 acres (1,200 km2), Rancho Los Nietos, as a reward for his military service and to encourage settlement in California. The area of Nieto's land grant was reduced in 1790 as the result of a dispute with Mission San Gabriel. Nonetheless, Nieto still had claim to 167,000 acres (680 km2) stretching from the hills north of Whittier, Fullerton and Brea, south to the Pacific Ocean, and from what is known today as the Los Angeles River east to the Santa Ana River. Nieto built a rancho for his family near Whittier, and purchased cattle and horses for his ranch and also planted cornfields. When Nieto died in 1804, his children inherited their father's property.
At the time of the Mexican–American War, much of the land that would become Whittier was owned by Pio Pico, a rancher and the last Mexican governor of Alta California. Pio Pico built a hacienda here on the San Gabriel River, known today as Pio Pico State Historic Park. Following the Mexican–American War, German immigrant Jacob F. Gerkens paid $234 to the U.S. government to acquire 160 acres (0.6 km2) of land under the Homestead Act and built the cabin known today as the Jonathan Bailey House. Gerkens would later become the first chief of police of the Los Angeles Police Department. Gerkens' land was owned by several others before a group of Quakers purchased it and expanded it to 1,259 acres (5 km2), with the intent of founding a Quaker community. The area soon became known as a thriving citrus ranching region, with "Quaker Brand" fruit being shipped all over the United States. Later, walnut trees were also planted, and Whittier became the largest walnut grower in the United States. In addition to walnuts and citrus, Whittier was also a major producer of pampas grass.
