Is a creatinine level of 1.53 ok.?

Creatinin level: It is mildly elevated , u need to watch it.

High creatinine: The blood level of creatinine is related to one's weight, sex, race, age. A woman 75 years old weighing 110 lbs with a creatiine of 1.4 has worse kidney function than a male, with the same creatinine level, aged 35. You should see a nephrologist and have a 24 hour urine collection to see what your kidney function is. He/she can order tests to see if you have anything that can done to lower it.

High for a "she": It would be normal for a muscular man; when i was lifting weights daily i ran as high as 1.6 this is just a bit high for a woman who is not an elite athlete, and you'll want to watch it, and especially take note of whether you may be hypertensive.
