What should I do if the total number of bacteria in urine is high?

With the improvement of medical conditions, we go to the hospital for check-ups every year. Urine test is one of the tests. By checking the urine and testing the composition of the urine, we can know which part of the human body has the disease. This is a very advanced detection method. Now there is a urine culture. By culturing the urine, we can know which bacteria are contained in the urine. So what should we do if the total number of bacteria in the urine is very high?

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 done to guide the doctor to use antibiotics accurately and in the right amount, killing the bacteria as soon as possible and giving you a healthy urinary system.

1. The normal value is <1×106 colonies/L (<1×106 colonies/ml). (Note: The specific reference value depends on each laboratory.)

2. Clinical significance

(1) <1×105 colonies/L: contaminated urine.

(2) <1×105 to <1×106 colonies/L: suspected urinary tract infection.

(3) >1×106 colony counts/L: urinary tract infection.

3. Precautions

(1) Clean the vulva before collecting urine. The container used should be clean and uncontaminated. It should not be mixed with chemical substances such as detergents, disinfectants and preservatives, so as not to affect the examination results.

(2) Urine should be sent for testing immediately after being collected to avoid incorrect test results due to urine being left alone.

(3) If the colony count in midstream urine culture is less than 1000 (<1000/mL), it is mostly due to in vitro infection.

(4) If you have been using antibiotics or diuretics, you should report this to your doctor immediately.

(5) Urine specimens should be collected under strict aseptic conditions: midstream urine is generally collected. For female patients, the vulva should be cleaned with soapy water first, then washed with sterile water, and dried with sterile gauze. The patient should be allowed to urinate, and the first-stream urine should be discarded. The midstream urine should be collected in a sterile container with a urine volume of about 10 mL. For male patients, the urethral opening should be cleaned with soapy water first, and then rinsed with clean water. Those with long foreskin need to turn back the foreskin for flushing, and then collect the midstream urine. Clean and disinfect the baby's genitals, place the mouth of the sterile vial against the urethra and fix it with tape, and wait for the urine sample to be sent for testing.

(6) Bacterial culture and drug sensitivity testing should be carried out together.
