i-STAT Creatinine - waived

With TJC no longer accepting COLA as an accrediting agency we are exploring all of our options for a clinic office.  One of the options that we have discussed is switching from testing Creatinine and eGFR on the StatSensor, which is non-waived to the i-STAT which could be used as waived (only venous blood in LiHep tube) and that would eliminate the need for an accrediting agency at this location as this is the only test performed there.  Does anyone have any input on the i-STATs for Creatinine testing?  I am unfamiliar with the i-STAT and we do not have them for any testing at any of our locations.  I don't believe the i-STAT calculates the eGFR, which I know would be needed. We use RALS and Meditech Expanse so I believe there may be a way to make a calculation occur when results are transmitted.  Does anyone have experience with implementing the i-STAT creatinine testing?  Any procedures, validation processes, pros, cons or any other information you could provide would be helpful.  My email is aholland@catawbavalleymc.org if anyone would prefer to respond in that manner.  
Thank you!

We use the iSTAT creatinine in all our Radiology CT areas. Staff find it easy to use and like the fast turn-around. We are RALS - Cerner. Once the result goes to Cerner, Cerner does the GFR calculation. We have it built as part of a WB creatinine panel. The Abbott Technical Reps are a great resource for helping get the testing set-up for your facility. Reach out if you need any help or questions. 

We utilize the iSTAT for Creatinine testing here in our Radiology department. We perform this test under a waived status. It was easy to implement and begin testing. The iSTAT does not calculate the eGFR. Our Radiology department utilizes https://www.niddk.nih.gov/health-information/professionals/clinical-tools-patient-management/kidney-disease/laboratory-evaluation/glomerular-filtration-rate-calculators website to get the eGFR. Initially we were going to attempt to have it calculated through RALS, however, there would be a slight difference in calculation of the eGFR between whole blood and serum creatinine. Our Pathologist did not want to have the laboratory responsible for that. 

Thanks to everyone who either responded on this platform or by email for all the input!
