Now, let follow the experts in Shijiazhuang kidney disease hospital and have a detailed understand about the reason why serum creatinine is low. Firstly, low creatinine can be caused by many reasons, which may be related to anemia, muscle malnutrition, leukemia, insipidus, etc. If the serum is lower than normal, firstly, it is necessary to have an examination again. If BUN and creatininie both increase, and what’s more, the ratio of BUN and creatininie is relatively low, it indicates that there may be renal damage.
The normal ratio of BUN and creatininie is 20.00-100.00. When the ratio is less than 20, we consider there probably has existed renal damage. And if the ratio is more than 20, it indicates that prerenal factor dominates.
There are various factors which can cause low serum creatinine. The index of BUN is easily influenced by many other factors. So we can not judge renal function just by BUN. In addition, BUN can also increase with the damage of kidney damage. So the ratio between them can decreased to some less than 20. If it is due to prerenal factor, BUN usually increases more, and the ratio usually increases to more than 20.
