Blood creatinine 118μmol/L, B ultrasound normal is usually seen in physiological factors such as strenuous exercise or after eating a large amount of meat, usually after the removal of triggers can be returned to normal, without special treatment; can also be seen in pathological factors such as acute glomerulonephritis, chronic nephritis, and other early renal lesions and other diseases, usually need to be actively standardized treatment. Blood creatinine is a nitrogenous metabolite of the human body, mainly excreted through the kidneys, and its normal range is 53-106umol/L for men and 44-97umol/L for women. 118μmol/L creatinine is out of the normal range, and it is recommended to consult a doctor in time. Due to the slight difference in the test standard of each hospital, the normal reference value range also has some differences, it is recommended to standardize the interpretation based on the actual report. 1. Physiological factors: such as strenuous exercise or consumption of large quantities of meat, blood creatinine can be elevated, B ultrasound is normal, without special treatment, usually in the removal of the causative agent can be restored. 2. Pathological factors: such as acute glomerulonephritis, chronic nephritis, lupus nephritis and other diseases, the early stage of ultrasound can be no abnormal renal manifestations, it is recommended that the patient consult a doctor in a timely manner, comply with the doctor’s instructions to standardize the treatment, and actively control the condition, so as to avoid delaying the disease. If the blood creatinine is found to be elevated, it is recommended that the patient should consult a doctor in time to further improve the urinalysis and other related examinations, and if necessary, carry out renal puncture biopsy to clarify the condition and standardize the treatment under the guidance of the doctor.
