Fentanyl testing for Vehicles

Criminals sometimes steal cars to use for illegal activities, including drug-related ones. If you suspect your car was used for illegal drug activities, you need to test it for fentanyl. In addition, if you are buying a used car you may want to have it tested for fentanyl to be on the safe side. This is especially true if you have have younge children or elderly parents.

When you ask us to test your stolen vehicle in California, we will provide a concise and clear result. When we perform fentanyl tests on stolen vehicles, we also work with insurance companies.

How to Test for Fentanyl in Vehicles, Homes and Offices.

We use a variety of methods to determine if there is fentanyl in cars (especially stolen ones), offices, homes and libraries washrooms.

These methods include: 

Depending on your circumstances, you may choose to test with surface wipes or air samples.

Surface wipes are used to remove a stain from an environment (vehicles or offices, homes, bathrooms, etc.). We are testing for fentanyl on the surface we're wiping. These wipes can pick up the smallest amount of fentanyl residue. We can also use air sample methods as an alternative. Air samples are collected and analyzed in the testing environment. Analysis of the air sample allows us to detect fentanyl, even at low concentrations.

Due to its high potency, fentanyl is dangerous for testing or detection. Only trained professionals should perform the task. If you suspect that there is fentanyl in your car, office, home or other environments, contact a professional testing agency such as ours.

Marijuana Smoke Residue Testing

Marijuana Residue Testing

Marijuana Smoke Residue Testing

Smoke of any kind is injurious to the lungs, especially for kids and older people. Marijuana Smoke is more dangerous as it contains cannabinoids - psychoactive and non-psychoactive - that can cause cerebral hyperactivity and euphoria. THC and CBD, despite being publicized as being beneficial in some medicinal sense, can cause injury to the lungs when cannabis buds are burned.

To successfully test for marijuana smoke residue in your home, the cheap home test kits won't suffice. You need a professional laboratory to test your air quality for THC and other cannabinoids to make sure it's safe for your kids and elder relatives. It's also essential that you know the level of cannabinoids in your home's air if you have individuals with respiratory issues. This test is especially important if you suspect there has been marijuana smoke in your home.


Air scrubbers

Invisible Impact

Want a good reason to get methamphetamine testing? Meth residue is completely invisible. You won't be able to smell it, either. While meth residue can stick around for years, you may never know it's there.


E. coli Testing

Escherichia coli, (aka) E. coli is a bacterium most commonly found in the intestines of warm-blooded organisms. You can develop an E. coli infection if you ingest this strain of the bacteria, often ingested when eating contaminated food.

The symptoms of E. coli infection usually last about 5 to 10 days. Those with moderate to mild symptoms usually recover on their own without much in the way of treatment. Thankfully, the infection normally quickly dies down on its own. For the kinds of E. coli associated with diarrhea, antibiotics will shorten the length of time you have symptoms and will most often be used in moderately severe cases.


Post Fire Air Quality Testing in the California Region

Air Quality Testing After a Fire in the California Area.

The suitability of an area or home for habitation after a fire incident is dependent on the levels of physical and chemical contaminants, as determined by post-fire air quality testing. Fire residues comprise the physical and chemical components, and while the physical residue is relatively easy to remove, the chemical residues can remain in a home or area for many months, sometimes years.

In California, wildfires and structural fires are not new to its residents. The residues from these fires expose them to some health hazards that can be avoided by employing the services of an indoor post-fire air quality testing firm, to ascertain if the levels of chemical residues in their homes and vicinity are safe for them.

Tobacco Residue Testing in California

Tobacco smoke is easily detectable by a humans' sense of smell. The nose picks up on nicotine easily and differentiates it from other chemicals. However, due to a large number of chemicals in tobacco smoke - over 4000 chemicals - it is difficult to determine if there's tobacco smoke in the air, especially in the limited presence of nicotine.

Accredited laboratories, like the ones we use, have special methods for detecting nicotine-limited smoke, especially secondhand and thirdhand smoke. We analyze smoke samples to identify some chemical markers that ascertain the levels of the low volatility chemicals such as acrolein, arsenic, hydrogen cyanide, and naphthalene, among others, in tobacco.
