The system includes a computing device, a pow- 10 er supply, one or more sensors, and at least one tracer agent that fluoresces _,\ when exposed to electromagnetic radiation. The electromagnetic radiation is detected using the sensors, and the rate in which the fluorescence decreases in the patient is used to calculate the renal glomerular filtration rate in the patient. 10 FIG. 2 [Continued on next page] 20 _\ ,12 WO 2019/084475 Al I 0111 111111110111111 0111 11111 111 1101 II III 11111 VIII VIII VIII VIII EH 1111111111111111 TR), OAPI (BF, BJ, CF, CG, CI, CM, GA, GN, GQ, GW, KM, ML, MR, NE, SN, TD, TG).
