Urine

Urine is the most common sample used for drug testing at our lab and around the country. When we take substances into our body, whether food or drugs, our body breaks those substances down into parts that we can use to fuel, change, or otherwise affect our body processes. The by-products of those processes are called metabolites, and they are removed from the body via urine.

Hair Follicle

Hair drug testing is extremely accurate as hair growth is fed by the bloodstream. Drug molecules are deposited in the blood when used, the bloodstream simply creates a fingerprint of drug use right within the hair shaft (or hair follicle). This history of drug use grows out with the strands of hair, and stays in the hair as long as the hair is present; telling a comprehensive story of what types of drugs have been present in the body.

Saliva

Saliva drug testing is a fast, easy, unobtrusive way to detect very recent drug use. When someone uses drugs, the substances travel throughout the body, affecting different body systems. Traces of indicators of the drug will appear in different body fluids, including saliva. By swabbing a testing subject's inner cheek and analyzing the saliva in our Texas lab, traces of recent drug use can be found.

Fingernail

A fingernail drug test is a non-intrusive way to obtain a deep history of an individual's past drug use. A fingernail drug test isn't ideal for quick results but will provide a deep history of potential drug use. Paired with a urinalysis, fingernail drug testing will offer a comprehensive picture of both recent and past drug use.

Sweat / Skin

Using a skin patch to monitor a person for future drug use is a great way to both encourage positive drug choices and to enforce drug policies. A specially designed testing patch can pick up on trace indicators if affixed to a drug user's skin. As long as the patch remains affixed to a person's skin, any instance of drug use will be recorded, resulting in a positive test.

Environmental

Environmental drug testing in Texas is the testing of an area or an individual for heavy metals (such as mercury, lead, cadmium, chromium, arsenic), or other unknown substances (both drugs or biological substances). It can also assist in identifying unknown syringes and other toxins or poisons. Quickest Labs can work with you to achieve a drug free workplace is to implement employee drug testing program.

DOT Drug

The US Department of Transportation (DOT) requires drug testing for safety-sensitive employees for the six agencies under the DOT umbrella (FMCSA, FAA, FTA, PHMSA, USCG, FRA). Quicktest Labs in Texas offers comprehensive DOT testing solutions including drug testing and alcohol testing services. Our certified lab specializes in both DOT and non-DOT drug testing services as well as DOT program development and management.

Steroids

Frequently, steroids are used by those wishing to gain an edge in a sport or area of physical competition. As a result, steroid testing programs in Texas are often instituted with the goal of preserving competitive balance and a level playing field across all participants. Quickest Labs can help school systems, sports leagues, and other concerned parties design and implement steroids testing programs that will help them achieve their specific drug use monitoring and prevention goals.
