Urine protein 3+ can not directly determine how many stages of kidney disease. The stage of kidney disease is usually based on glomerular filtration rate.
The influencing factors of glomerular filtration rate are blood creatinine, age, weight and so on. If the glomerular filtration rate, i.e. GFR, is greater than or equal to 90 ml/min, it is usually stage 1, and the goal of this stage is to treat the underlying disease, slow down the progression, and reduce the risk of cardiovascular disease.
If the GFR is between 60 and 89 ml/min, it is in stage 2, and a GFR between 30 and 59 ml/min is in stage 3. This stage requires evaluation and treatment of complications.
If the disease continues to progress and the GFR is between 15 and 29 ml/min, it means that the GFR is severely decreased and renal replacement therapy needs to be prepared. If the GFR is less than 15 ml/min, dialysis or renal transplant replacement therapy is usually required.
The appearance of urine protein 3 + or glomerular filtration rate abnormalities should be timely regular hospital consultation, under the guidance of physicians to improve the relevant examinations, and targeted treatment.
