Bloodwork for ct scan but creatinine egfr?

When preparing for a CT scan, particularly one that involves contrast material, bloodwork to assess kidney function is often done, typically measuring creatinine and estimating glomerular filtration rate (eGFR). Elevated creatinine levels or a low eGFR can indicate impaired kidney function, which may increase the risk of contrast-induced nephropathy. If kidney function is compromised, healthcare providers may decide against using contrast or take additional precautions. Always discuss any concerns with your healthcare provider prior to the procedure.
