Incidence in patients having non-emergency CT scans with intravenous contrast agent is reported to be less than 1% (Ozkok et al. If AKI is not treated promptly, levels of salts and chemicals in the body can increase, which affects the fluid balance in the body and how well other organs work.Ģ.4 Post-contrast AKI (PC‑AKI) is a sudden deterioration in kidney function within 48 to 72 hours of administering intravenous iodine-based contrast agent. It could also reduce the number of cancelled scans, which is important for patients.Ģ.3 AKI covers injury to the kidneys from a number of causes it often happens as a complication of another serious illness. If a person does not have a recent eGFR measurement, their CT scan could be cancelled and rescheduled while a creatinine test is processed in the laboratory.Ģ.2 Using POC creatinine tests before outpatient contrast-enhanced CT scans in the radiology department could minimise the risk of kidney injury. If a person has a low eGFR, intravenous hydration can be offered before the scan to reduce the risk of AKI. Intravenous iodine-based contrast agents used in CT scans can cause acute kidney injury (AKI), particularly in people who are at high risk and those with known kidney dysfunction. The focus of this assessment is POC creatinine testing to assess kidney function before people have intravenous contrast for CT imaging. This can show whether the kidneys are working properly. 2.1 Point-of-care (POC) creatinine devices allow rapid measurement of creatinine levels and calculation of estimated glomerular filtration rate (eGFR).
