Fingernail Drug Testing in Texas

Quick, Clean, Reliable Testing. No Waiting. Walk-ins Welcome.

A fingernail drug test is a non-intrusive way to obtain a deep history of an individual’s past drug use. But how does fingernail drug testing work? When an individual uses drugs, those drugs spread throughout the person’s body affecting almost every body system. As the drugs are metabolized, they continue spreading throughout the body via the bloodstream. Trace indicators of drug use are left behind in a few places, even long after drug use. One of these places is inside fingernails and toenails. By analyzing a person’s fingernails for these trace indicators, one can determine whether or not the person has used drugs within the last several months.

Ease of Sampling

A Texas fingernail drug test is mostly similar to a hair drug test, in terms of the accuracy and range of the test, but a fingernail sets itself apart in cases where a hair is not easily obtained. If a test subject happens to be bald and doesn’t want to provide body hair, a fingernail test is a suitable alternative. The sample collector simply takes clippings from each of the subject’s ten digits, and files them to obtain a nail dust for testing. The clippings and dust are tested for drug indicators and your accurate results are sent to you quickly.

Deep History of Drug Use

Because of the durability of fingernail tissue, fingernail drug analysis provides a deeper history of drug use than drug tests that analyze body fluids like urine or saliva. While those tests may be accurate for relatively recent drug use, a fingernail drug test can measure up to eight months of past potential drug use. While fluid tests are the most commonly used drug testing methods in Texas, a longer term test like fingernail or hair testing might prove more valuable and efficient for some Texas drug testing programs and schedules.

No Known Alterants

An important aspect of a drug test’s value is how easy or hard it is to “beat” it or skew the results. In some cases, certain drug tests can be influenced by the ingestion of “alterants” by the provider of the specimen. Alterants are chemicals that interact with the indicators of drug use, eliminating them or masking them. There are no known alterants that can interfere with drug indicators found in fingernail tissue. Alterants are one less variable you need to worry about with nail drug testing from Quicktest Labs.

Fingernail Drug Testing

While not ideal for random or “for-cause” testing, because it takes up to a week for drug indicators to be found in a user’s fingernail tissue, fingernail testing is ideal for situations in which a long-term pattern of drug use is sought. That makes fingernail testing one of the best methods for pre-employment screenings in Texas. And by combining Texas fingernail drug testing with a short-term test like urinalysis, you can get a comprehensive history of the testee’s drug use. With Quicktest Labs, you can always know that your Texas fingernail drug tests are done professionally, quickly, accurately, and affordably.
