Creatinine, generally refers to blood creatinine, blood creatinine 76μmol / L if belongs to the adult, belongs to the normal range; if belongs to the child, is on the high side. 1. Adult male: the normal value of blood creatinine is usually between 53~106μmol/L, so blood creatinine 76μmol/L is normal. 2. Adult females: Normal blood creatinine values are generally between 44 and 97 μmol/L, so a blood creatinine of 76 μmol/L is also normal. 3. Children: the normal value of blood creatinine in children is generally between 24.9~69.7μmol/L, so blood creatinine 76μmol/L is on the high side, which can be seen in physiological elevation, such as strenuous exercise, eating a lot of meat; there may also be acute and chronic renal insufficiency, in which edema, high blood pressure, nausea, vomiting and other symptoms may occur. If the creatinine value is abnormal or there is any discomfort, it is recommended that the patient should consult a regular hospital to improve the relevant examination and diagnosis and treatment.
