Urine testing collection midstream

Midstream urine is contaminated with germs and therefore less meaningful.
Won for an investigation into the urine as a so-called midstream urine. This designation will be implemented by the method of how to obtain one. A urine sample can only be used if no impurities are present by germs from the field of external sexual organs. Therefore, a proper collection of urine specimens in men is easier than in women. All urine tests should be carried out usually with mid-stream urine.


The procedure for obtaining the midstream urine should be strictly adhered to.
Before urinating, the genital area with water and cleaned if necessary with a mild cleaning agent and then dry it well. Then, the first jet is discharged urine. He is not recycled because it contains germs that are on the urethra. By the first beam, the urethra is "flushed" and cleaned. Then the second (middle) jet-hence the name in a sterile, the doctor or nurse handed out cups collected. The last Endstrahl is again discarded. When obtaining the midstream urine during urination is not paused. The sterile container must be kept in continuous stream of urine under the beam. If the urinary stream is interrupted, the risk of bacterial contamination.


In women, the production of sterile midstream urine is more difficult than in men.
In women, the recovery of a sterile midstream urine because of the anatomical proximity of the urethral outlet to the vagina and the labia is much more difficult. Physiologically, there are found many germs, so that a proper sampling is possible only under absolute sterilization of the entire genital area. This requires the assistance of a nurse or a doctor. For this reason, in women the urine collection for diagnostic purposes with the help of a catheter is not uncommon, while in men it is only in exceptional cases like this. This form of urine collection is also called urinary catheter. A catheterization is used whenever the production of mid-stream urine in the normal way is not possible.
