Urine examination culture
NEW: (urethra with stabilizer)
In this study, two tests are performed from morning urine:
- urine culture and
- antiobiogram / germ count determination if necessary
(Other analyses:code KUL (culture urine); material special urine tubes with stabilizer )
- White blood cells (Leukocytes).
- In the context of a urinalysis, the presence of leukocytes (white blood cells) indicates a possible urinary tract infection. These cells are sent to the urinary tract by the immune system to fight infections.
- Urine culture
- A urine culture is a test in which urine is analyzed to detect the presence of bacteria or other microorganisms that may cause a urinary tract infection. It helps identify the specific bacteria and is useful in determining the appropriate antibiotic treatment.
- Determination of colony-forming units (CFU) by culture
- This refers to counting the number of bacteria in urine by culture methods. The number of colony-forming units gives an indication of the amount of bacteria present in the urine.
- Aerobic antibiogram
- An aerobic antibiogram is a test used to determine which antibiotics are effective against bacteria identified in a urine culture. It helps choose the most effective treatment for a bacterial urinary tract infection.
- White blood cells (Leukocytes).
Together, these tests give a complete picture of the presence and nature of a urinary tract infection and help in choosing the right treatment.
S: sensitive at standard exposure
I: sensitive at elevated exposure
R: resistant
MHK = Minimum inhibitory concentration in mg/l.
In the event that a pathogen is marked with an *, hospitals and ambulatory surgery facilities are subject to reporting requirements according to IfSG §23 (1).
Antimicrobial susceptibility is interpreted according to the European guidelines (EUCAST). Here it is important to note that the interpretation is only valid if the doses used correspond to the recommendations of EUCAST.
If antibiotics are rated as I (sensitive to increased exposure), it means the therapy requires a high dose.

For aminoglycosides tested as S (sensitive at standard exposure) (Amikacin, Gentamicin, Tobramycin), monotherapy is not recommended. However, the antibiotic can be used in combination with a second, effective therapy (exception: urinary tract infections caused by Gram-negative bacteria).
For the following antibiotics, the interpretations apply only to uncomplicated urinary tract infections: Cefuroxim p.o., Cefpodoxim, Mecillinam, Phosphomycin p.o., Nitrofurantoin, Trimethoprim.
Only if e.g. bacteria are positive is this tested further.
