What are the important aspects of diagnostic indicators for kidney disease?

Patient's question:

General fatigue, hematuria unclear

Doctor's answer:

Hello, your condition is that the urinalysis shows occult blood and protein. Since a urinalysis is only a very rough screening test, you must undergo further related tests to determine the cause and severity.
Recommendation: It is recommended to repeat the urinalysis and add a urinalysis of red blood cell morphology to distinguish the source of hematuria. Additionally, perform a urine microalbumin test and a 24-hour urine protein quantification along with creatinine clearance (CCR). This will help assess the total amount of protein leakage and provide a comprehensive evaluation of renal function. Only in this way can the diagnosis and condition be clearly determined.
