Creatinine

Creatinine was a substance that was found in the blood sample analysis of the Trandoshan Nack Movers's blood by Coruscant Security Force crime scene analysis droid Russo-ISC after Movers was murdered with sennari poison in 7958 C.R.C. Movers's blood had a concentration of 130 creatinine, which was not considered a contaminant by the droid.

Behind the scenes
Creatinine was first mentioned in the 2018 reference book Star Wars: Scum and Villainy: Case Files on the Galaxy's Most Notorious, which was written by Pablo Hidalgo.
