If creatinine 118μmol/L is caused by physiological factors such as strenuous exercise, eating a lot of meat food, it needs to be rechecked after 2~4 weeks; if it is caused by acute elevation due to urinary tract obstruction, pharmacological renal injury and so on, it needs to be rechecked in 3~5 days; if it is caused by chronic elevation due to chronic nephritis, diabetic nephropathy and so on, rechecking in 3~6 months is enough.
Blood creatinine can reflect the situation of glomerular filtration rate, and the glomerular filtration rate may be affected if it is high.
Physiological factors such as dietary meat food accounted for more, or patients recently exercise more, or muscular athletes, etc., can lead to a mild increase in blood creatinine, at this time the general 2 ~ 4 weeks after the review can be.
Due to urinary tract obstruction, drug-related kidney injury, gastrointestinal bleeding, heart failure, etc., it is recommended to review in time and closely observe the changes in the condition, and it is generally recommended to review the relevant indicators in 3~5 days to assess the condition.
Chronic nephritis, diabetic nephropathy, polycystic kidney, hypertensive nephropathy and other causes of chronic elevation, the disease is generally slower development, if there is no recent use of a large number of diuretics, no difficulty in controlling hypertension, anemia, fever, etc., it is recommended to review the examination in 3~6 months.
When abnormal creatinine test occurs, it is recommended that patients must be regular hospitals, follow the doctor’s instructions in the prescribed time to review, clarify the causes and standardize the treatment.
