Making a urine drug test requires four steps: collection, selection, confirmation, and review. Urine samples are commonly used to prove the presence of various drugs in a person system, because this test is simple and reliable. Not to mention, urine tests are much cheaper than other types – laboratory technicians usually are not necessary.

Similarly, the drug test kits used for urine tests are easy to store and have a long shelf life. Some teams come in packages with gloves and cups, which are very easy to use. Twelve different drugs can be tested through this method, but there are some drawbacks. Contamination of urine samples is not difficult, only a three-day window of detection, and some issues finding the process invasive and embarrassing.

Here is the process for carrying out a urine test for drugs:

• A strip of the temperature in the container collecting the samples of guards against substitution and fraud. The manipulation is obvious to drugs and drug metabolites. If no positive results, a second test is carried out to confirm this. A doctor or nurse checks the confirmed positives for legitimate prescription drugs can be excluded as contributors the positive finding.

• Some urine samples can be examined in the drop and the results can be known within minutes – others are examined in a laboratory. The negative results are accepted as is and are not confirmed or reviewed.

• Urine samples showing the presence of drugs in the initial detection are examined again in a laboratory environment under two analysis techniques called gas chromatography and mass spectrometry. Through gas chromatography, the various substances in urine are separated and by mass spectrometry, are shown as positive or negative.

• The laboratory results are then written and urine donors or authority that requires proof.

Warning about urine tests

The government has some new guidelines for testing drugs that require all laboratories to do "display integrity," especially for testing urine. Since there is no fraud, therefore, in which people just use other people's urine to submit a drug test, the effectiveness of the tests in question. Moreover, laboratories have been ordered not to search only marijuana and other illicit drugs, but for other additives that contamination of evidence (such as dilution and adulterants).

The clinical microbiology laboratory is often a sentinel for the detection of drug resistant strains of microorganisms. Standardized protocols require continual scrutiny to detect emerging phenotypic resistance patterns.  The timely notification of clinicians with susceptibility results can initiate the alteration of antimicrobial chemotherapy and improve patient care. It is vital that microbiolo...
