The concept of creatinine values higher than the normal value can be called high creatinine, creatinine including serum creatinine and urine creatinine, serum creatinine to measure renal function but more meaningful. So high creatinine usually refers to high blood creatinine.
The normal value of blood creatinine in each hospital is different. In general, the normal standard of serum creatinine is 44-133umol/L. When the blood creatinine exceeds 133umol/L, the kidney is damaged and has renal failure and renal failure. (133umol/L above is the stage of inflammatory injury, 186umol/L is renal function injury, and 451umol/L is renal failure period).
Serum creatinine is a common index for the detection of renal function. In the normal range of blood creatinine, it is not wrong to think that the function of the kidney is completely without problems. The serum creatinine value does not reflect the status of renal function in time and accurately. When the majority of human kidney is subjected to pathological damage and the rate of glomerular filtration rate falls to a large proportion (more than 50%), the situation of elevated serum creatinine is likely to show up in clinic.
The changes in serum creatinine concentration are mainly determined by the glomerular filtration rate (glomerular filtration rate). So, creatinine should be paid attention to. The concentration of creatinine increased with the decrease of filtration capacity. Most of the normal value of blood creatinine means kidney damage, and blood creatinine is more accurate in response to damage to the renal parenchyma and is not a sensitive indicator. As the glomerular filtration rate drops to the normal 1/3, the blood creatinine increases significantly.
It can be seen that serum creatinine does not reflect kidney disease in time. Therefore, more examinations should be done to detect nephropathy in time. Early treatment and attention to physical health are the most important.
