Usually, relying solely on blood tests for kidney function cannot diagnose nephritis, and it needs to be further diagnosed by combining with urine routine, 24-hour urine protein quantification, and renal puncture biopsy.
The full name of nephritis is glomerulonephritis, which is a general term for a group of diseases. Patients mainly present with hematuria, proteinuria, hypertension, edema, etc. Some patients may have renal function impairment.
Checking nephritis usually starts with urine routine to observe whether proteinuria or hematuria occurs. If proteinuria occurs, after excluding the possibility of physiological proteinuria, it suggests the possibility of nephritis. When the urine routine suggests positive urinary occult blood, it is also necessary to determine the morphology of red blood cells, if abnormal, it suggests nephritis. Renal puncture examination can further clarify the type of nephritis pathology.
Blood tests are usually only able to determine renal function, which is a guide for patients with reduced renal function.
If patients need to clarify whether they are suffering from nephritis, it is recommended that they go to a regular hospital in time to have the test results prescribed and evaluated by a professional doctor.
