What can female urine culture test?

Friends who work in the medical field know that, whether in some research institutes or hospitals, there are some inspectors checking urine every day and conducting urine culture. The main purpose of doing this is to help patients diagnose diseases or conduct related academic research. But for friends who are not engaged in this kind of work, their actions are a little incomprehensible. So, what can female urine culture test?

Urine culture refers to the growth of bacteria in normal urine. Normal urine should be a sterile liquid, but there are various bacteria on the surface of the human urogenital tract. Since the pH in the female vagina is acidic, there are generally no pathogenic bacteria, but there are many conditional pathogens such as lactobacilli. As the pH changes, the normal flora will also change. Therefore, urine culture should be performed in a sterile manner (it is best to clean and disinfect the external urethra under the guidance of a doctor) to eliminate interference from external bacteria and accurately detect whether there are bacteria in the urine, whether they are pathogenic bacteria or conditional pathogens.

If the result is <1000/ml, it is generally treated as a normal specimen.

If the result is 1000-100000/ml, there may be infection, and you should collect the sample for testing again or check again in a few days.

If the result is >100,000/ml, the patient is diagnosed with urinary tract infection and identification and drug sensitivity testing are performed.

If any of the bacteria such as Staphylococcus, Escherichia coli, diphtheroids, yeasts and Lactobacillus (female) are found in urine culture, it will cause urinary tract infection. Therefore, the significance of urine culture test is to monitor whether the human urinary system (including kidneys, bladder, and urethra) is healthy and sterile. If there is a bacterial infection, an antibiotic sensitivity test for the bacteria should be performed to guide the doctor to use antibiotics accurately and in the right amount to kill the bacteria as soon as possible.
