<s>[INST] Hi, Dr Grief, While going through a health screening and found my blood creatinine level was slightly above normal range, does it mean there is a serious problem with my kidney function while blood tests for other renal function indicators have shown within normal range. A microscopic urine examination was performed and  findings were normal?  I am 57 years old, female. I will be most grateful for your professional expertise. Thank you. Lena. [/INST] Hi raised creatinine is definitely dangerous though not life threatening. You should consult a nephrologist for full evaluation. But don't be panic. If you used excessive pain killers,it could be the cause. BP and sugar should be controlled if you have. Avoid non vegetarian diet. all the best. If you have any questions feel free to contact me. </s>
