What are the different types of urine test kits?
There are two generally accepted types of testing trains on the market, on -site tests and tests outside the locality. The on -site test is a test that provides almost immediate results and the test outside the locality requires laboratory verification and may take a week or more to be analyzed and delivered. For urine tests, they are used for screening and alcohol. Testing outside the site is usually limited to screening of addictive substance abuse. The urine sample is collected and the test belt is placed in the sample and leaves for several minutes to sit. When the results are prepared, different colors on the test strip indicate the presence of drugs in the urine if they are detected. Immediate results are often necessary after accidents in the workplace, because many liability insurance providers require testing immediately after the incident to determine where the use of addictive substances played a factor.
On -site tests can also be used to test recent alcohol use. Alcohol screening is particularly usedCounteps in jobs that prohibit alcohol consumption within the set time frame before starting the shift. Airlines pilots, heavy building machinery operators and people in other high -risk positions with high responsibility are usually subject to random alcohol tests to verify that these regulated standards are followed.
Test sets outside the site use the same method of sampling as sets on site. Samples are usually collected in the approved device to better ensure that the sample used in the screening of the drug is not subject to any potential contamination or change. Sampling collectors are trained to test the temperature and concentration of urine to reduce the chances of changes in the sample. After verifying these details, experts are sealed and sent to the laboratory to the laboratory outside the locality.
After receiving the sample in the laboratory, the sample is divided into the DVOfor parts. The first half is tested by means of an immunoanalysis analysis. If the results show the potential presence of illegal substances, the second test will take place on the remaining half of the sample using gas chromatography and weight spectrometry to verify positive reading. The use of the second round of testing and complex methods of scientific testing significantly reduces the chance of false positive reading.
kits for urine test sets for various substances such as cocaine, barbiturates and heroin. The amount of time that occurs trace amounts of specific substances in the urine will differ from the drug for the drug. The potential detection time can range from a few hours to a few weeks after using the drug.
