In many kidney disease patients, there are numerous patients suffering from glomerulonephritis, and many kidney disease is initially to glomerulonephritis into, if you are a patient of the disease, you must pay attention to it, early to the hospital for treatment, so as not to bring serious health risks to themselves. What are the main checkup items for glomerulonephritis? 1, blood complement measurement: except for individual cases, glomerulonephritis early in the course of the disease, blood total complement and C3 are significantly decreased, 6 to 8 weeks after the return to normal. This regular change is typical of this disease. There is no significant correlation between the degree of decrease in blood complement and the mild signs of acute glomerulonephritis, but if hypocomplementemia persists for more than 8 weeks, other types of nephritis should be considered, such as membranoproliferative nephritis, cryoglobulinemia or lupus nephritis. 2, cytology and serology: the positive rate of β-hemolytic streptococci cultured from pharyngeal or skin infection foci after the onset of the patient is about 30%, which is not easily detected in those who receive penicillin therapy early. Streptococcal infection will produce the corresponding antibodies, often through the detection of antibodies to confirm the antecedent streptococcal infection. The treatment removes the proliferating extracellular matrix and improves the microcirculation of the kidney. In summary, this is the examination method of glomerulonephritis. 4. Other tests: circulating immune complexes and cryoglobulins can be measured in some cases in the acute phase. Usually, typical cases do not require renal biopsy, but if it is difficult to differentiate from acute nephritis; or if there is still hypertension, persistent hypocomplementemia or renal impairment 3 months after the disease Then how to do prevention for glomerulonephritis? 1, there are a large number of media reports, many kidney disease patients are aggravated because of the indiscriminate use of drugs and the resulting hematuria, which can be seen that drug-induced kidney damage is increasing, nearly 25% of renal failure patients indiscriminately taking nephrotoxic drugs related. Therefore, patients should be under the guidance of a doctor to take drugs reasonably and correctly to reduce the occurrence of drug nephritis. 2, as social competition began to intensify, the spiritual and material civilization improved, and because the social groups appear aging. Therefore, the number of hypertensive patients and diabetic patients is increasing year by year, these two diseases are very likely to induce nephritis, leading to uremia. So, as much as possible in daily life flat to develop good habits, found diabetes and other diseases timely treatment, good control of blood sugar and blood pressure, is an effective way to reduce the incidence of nephritis. 3, in addition, always do not forget to strengthen the body, enhance their own immunity, because the best way to prevent glomerulonephritis is physical exercise, enhance their own immune system, to prevent upper respiratory tract infections drink pharyngitis, tonsillitis and other diseases. When respiratory infections are prevalent, it is good to prevent the disease and take isolation measures. Once pharyngitis and influenza are found, they should be treated in a timely manner and should not be delayed. In many cases, it is the failure to prevent the disease when it is most in need of control that leads to serious consequences. The most important thing is to keep a good attitude, to check the condition when it is still stable, to observe the changes in the condition, to take protective measures, and not to blindly consult a doctor because of anxiety.
