Aims: To know the possible effects of the use of Ipomoea batatas starch gel with the measurement of creatinine and to provide a substitute serum separator other than the commercially available ones that are cheaper and without the possible interference with the results.
Study design: In this study, experimental method was used by the researchers.
Place and duration of Study: Isolation at Sto. Tomas, Batangas and Gelatinization at Adamson University between September 2018 and November 2018
Methodology: Isolation of the starch was done at Sto. Tomas, Batangas while gelatinization was conducted at Adamson University, Biology department. Creatinine determination was done at Beato-Caulin hospital using dry chemistry.
Results: The 0.2g/mL concentration showed the least interference and closest to the control while the .023 concentration showed lower results that the control.
Conclusion: The prepared sweet potato (I. batatas) starch gel is an active serum separator. The concentration 0.21g/mL has the least interference, thus, can serve as an alternative SST to the commercially available SST.
