Hi,

The values of creatinine is not a definite criteria to draw a line between serious or non serious clinical picture.

Any person with this numbers needs frequent follow up and monitoring.

Regards.

Chronic kidney disease is identified by a blood test for creatinine. Higher levels of creatinine indicate a lower glomerular filtration rate and as a result a decreased capability of the kidneys to excrete waste products. Creatinine levels may be normal in the early stages of CKD, and the condition is discovered if urinalysis (testing of a urine sample) shows that the kidney is allowing the loss of protein or red blood cells into the urine. To fully investigate the underlying cause of kidney damage, various forms of medical imaging, blood tests and often renal biopsy (removing a small sample of kidney tissue) are employed to find out if there is a reversible cause for the kidney malfunction. Recent professional guidelines classify the severity of chronic kidney disease in five stages, with stage 1 being the mildest and usually causing few symptoms and stage 5 being a severe illness with poor life expectancy if untreated. Stage 5 CKD is also called established chronic kidney diseaseand is synonymous with the now outdated terms end-stage renal disease (ESRD), chronic kidney failure (CKF) or chronic renal failure (CRF).

the usual causes for worsening of renal functions in this setting are:
1) poor control of blood pressure: ur pressures seem ok
2) ongoing infection: no history suggestive
3) intake of pain killers particularly nsaids : have u taken since u give history of abdominal pain
