General information on urine extraction
In order to minimize sources of error, a correct procedure for sampling is necessary. The following points should therefore be followed in principle:
Most microbiological studies require the extraction of mid-beam urine. Proper sample collection technique is necessary to avoid contamination by germs from the areas of the external sex organs.
The intended sampling should be carried out as follows.

Normally, however, it is the case that, for example, in a doctor’s office, the patient gets a cup pressed into his hand with the hint that please fill the cup, but if possible not completely to the edge. And that was often the complete instruction. As a result, the probability of relevant contamination of the sample is relatively high. How many false-positive or false-negative test results result from this has not yet been scientifically proven.
