Acute kidney injury (AKI) is a condintion characterized by reduced kidney function. There are several methods of diagnosing the condition, the most accepted is KDIGO, which classifies the disease into 3 stages. Delta check is the laboratory tool used to calculate the variation between the dosages of a current exam and your previous one. The objective of this work is to verify if the delta check can be used as a diagnostic aid for AKI. This study was developed through a scope review of the existing literature using keywords and descriptors. The searches in the databases resulted in 177 articles where after the elimination processes 6 articles were included for the study. The articles originated in the following countries: United Kingdom, United States and Canada, all in English. Each article had different rules for calculating the delta check and also different time limits between creatinine dosages, showing that each institution created rules according to the population served in their units. In all articles, delta check was proven to help, but in Kothari's article it gained more prominence because, in addition to creating an alert with delta check, the need for training of medical staff for the diagnosis of AKI was emphasized. It can be concluded that delta check helps in LRA, it is essential that each institution create its delta check rules.
