Comparison of the Indocyanine Green Clearance Test Using Conventional Blood Sampling and Finger Monitoring Methods

摘要

Background :The indocyanine green (ICG) finger monitoring method is a newly developed noninvasive method for the ICG clearance test. This study was performed to determine its clinical usefulness compared with the conventional blood sampling method. Method :The ICG clearance test was performed on 270 patients using both the conventional blood sampling method and the finger monitoring method simultaneously. The plasma disappearance rate of the ICG and the 15-minute retention ratio (ICG R15) were analyzed and compared with the conventional blood sampling method. Result :The plasma disappearance rate using the finger monitoring method was slightly lower than that of the conventional blood sampling method with good correlation (r=0.840, P0.001). Conclusion :As there was a good correlation between the conventional blood sampling method and the finger monitoring method, the latter method seemed to be clinically useful due to its convenience and accuracy.
