Who this trial is looking for
This trial is looking for adults with chronic kidney disease to test a new software that helps detect high potassium levels. Participants will have their potassium levels checked and use the software at home for a month.
Are You a Good Fit for This Trial?
Must be takingRAAS inhibitors
You may be able to join if
I am 22 years or older
I have been diagnosed with chronic kidney disease stages III or IV
I have a scheduled potassium test at the clinic
I have been treated with RAAS inhibitors or had high potassium in the last year
I can give my written consent
You may not be able to join if
I am 21 years old or younger
I have a pacemaker or implantable defibrillator
I have a history of certain heart block conditions
I have had potassium-lowering treatment before my ECG test
I have had recent trauma or significant medical events
I have physical limitations that prevent me from getting an ECG

The goal of this observational pilot study is to evaluate the investigational AK+ Guard™ software as a medical device (SaMD) for detection of moderate to severe hyperkalemia (serum potassium (K+) ≥ 6.5 mmol/L) in adults with chronic kidney disease (CKD).
Study objectives are:
* Arm 2A (Outpatient Diagnostic Accuracy): To generate a preliminary, real-world signal of the diagnostic performance of AK+ Guard™ when used in an ambulatory CKD cohort for identifying clinically significant hyperkalemia episodes (serum K+ ≥ 6.5 mmol/L) at the time of an outpatient laboratory draw.
* Arm 2B (Remote Patient Monitoring): To assess participant compliance, usability, and end-to-end system reliability of AK+ Guard™ when deployed for daily remote monitoring of CKD patients outside the clinical environment for up to four weeks.
