In this prospective observational study, urine samples were collected on admission (within 06 hours) and at 24 hours in ICU. Urine albumin to creatinine ratio (ACR) was measured on ICU admission (ACR1) and at 24 hours (ACR2) along with APACHE II scores, ICU length of stay and ICU mortality. Out of 99 patients in ICU, 73 survived while 16 patients died. All the parameters like ACR1, ACR2, ACR, APACHI II score and total hospital stay were higher in non-survivors as compare to survivors and show significant difference. To estimate the diagnostic accuracy, cut-off value of ACR2, if considered below than 30 mg/g, total 03 patients are covered with 95.9% sensitivity and 100% specificity, however if considered below 100 mg/g, total 54 patients are covered with 23.3% sensitivity and 92.3% specificity. In conclusion, the absence of significant microalbuminuria at 24 hours of ICU admission may help to predict severity as well as the outcome in the ICU patients.
