How Accurate Is Drug Testing In Urine

In recent years, people are finding themselves required to take random drug tests for a variety of reasons. Some of these reasons include: requirements for employment, military service, sports activities, legal reasons, drug rehab and so forth. We are aware what a positive reading can do to us, so we must find ourselves asking the question: How accurate is drug testing in urine? There are a variety of other means to test drugs, but urine testing is the most frequently used. It is easier to collect, there will be higher levels of drug concentrations, and the drugs stay in the urine for longer periods of time.

There are basically two tests used and the question remains: How accurate is drug testing in urine? The first test is Immunoassay screen which is the most commonly used because it is inexpensive and the test yields fast results. The second test is the GC/MS or gas chromatography/mass spectrometry. It takes longer for results and is more expensive, but the results are more thorough. For the most part, the Immunoassay screen is sufficient to get the results needed.

There are in some cases problems causing false negatives in the urine test and the person wise to the ways of the drug world may be familiar to these methods. They may be tampering with their urine test by using some of the following: bleach, vinegar, soap, lemon juice, table salt, etc. A person could use a high intake of fluids for a period before the test resulting in a false negative. These things would be more likely picked up in the GC/MS test. If a false negative is suspected, there are other alternatives as well, like a blood test, or a saliva test.

In many circumstances, the question prevails: How accurate is drug testing in urine? Is it possible to get false positives, and what causes them? Most certainly, false positives happen, often due to the person taking other medications that would cause the incorrect read. For example, do vaccinations cause false positives when combined with other medications that the person may be taking? Sometimes medications like ranitidine, a medicine for acid reflux reacts with the test itself. Fluorquinolone will combine with other medications and cause a false positive. It is imperative that one informs the doctor, clinic, whoever is reviewing the test results, of all medications currently being taken to avoid possible problems that could harm your life.
