Renal Function Six cannot check for kidney deficiency because the former belongs to Western medicine test while the latter belongs to Chinese medicine terminology. There are six tests in renal function six, and different positive values represent different meanings. Usually, if the patient’s kidney function is damaged, the creatinine and urea nitrogen in the six items of renal function will be higher than normal. And if the blood uric acid is high, it is mostly because of the existence of gout and other diseases. However, what Chinese medicine refers to as kidney deficiency mainly refers to the clinical symptoms, and patients with this syndrome may not necessarily have abnormalities in the six items of renal function. But there will be symptoms such as soreness of waist and knees, tinnitus and deafness, dizziness, infertility with uterine cold, frequent urination, impotence and premature ejaculation. Therefore, for patients with kidney deficiency, we can’t rely solely on the results of renal function six tests, but need to focus on the patient’s clinical manifestations.
