After a urinary tract infection, it is possible that the blood sedimentation may be elevated. Blood sedimentation is a non-specific indicator and can be elevated in the case of systemic infections, tumors and other diseases. It is not a specific indicator, but a non-specific indicator, and many diseases can cause it to rise. Therefore, in urinary tract infections, elevated hematocrit has no practical significance, but needs to rely on urine culture, urinary routine and other tests to reach a diagnosis, and also needs to be combined with the patient’s own symptoms, such as the presence of urinary frequency, urinary urgency, painful urination, etc. In addition to common urinary tract infections, non-specific urinary tract infections can also cause elevated hematocrit, such as tuberculosis of the urinary system, which can lead to elevated hematocrit, and tumors of the urinary system combined with infections, which can also lead to elevated hematocrit.
