Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
1. How consistent are the results between P1 and Nova in the emergency setting, including outliers, correlation, linearity, and bias?
2. Whether P1 can serve as a suitable alternative to Nova in the acute care setting for electrolyte measurement in the emergency environment.
Participants will be patients in the emergency department who will undergo simultaneous measurement with P1 and Nova during their emergency care to assess the performance of both devices.
Additionally, the study will investigate electrolyte levels in emergency patients, focusing on the prevalence of abnormal ionized magnesium (iMg2+) levels, the correlation between iMg2+ and total magnesium (tMg), and the clinical significance of iMg2+ measurement.
