Occult glomerulonephritis mainly manifests as hematuria or proteinuria, or it may not have any symptoms and need to be detected by examination. Occult glomerulonephritis is also called asymptomatic hematuria or (and) proteinuria, and patients mainly manifest glomerulonephritic hematuria or proteinuria, and some patients can have microscopic hematuria or increased foam in urine. However, most patients do not have any symptoms, and often can only find microscopic occult blood or a small amount of proteinuria through routine urinalysis and other related examinations, without edema, hypertension, kidney injury and other manifestations of chronic nephritis. Therefore, it is not possible to judge whether it is cryptoglomerulonephritis based on the presence or absence of symptoms, and it is necessary to improve the urine routine, renal function, 24-hour urine protein quantification, urine protein electrophoresis, protein of the week, and other related tests, and even renal biopsy to determine. It is recommended that the patient should go to the hospital in time, complete the relevant examinations according to the doctor’s instructions, make a clear diagnosis and take active treatment.
