Hypothesis
The AM 721 ion-selective electrode system can accurately measure sodium and potassium levels in plasma, urine, and whole blood.
Conclusion
The AM 721 system provides accurate and precise measurements of sodium and potassium, making it a practical tool for urgent testing.
Supporting Evidence
- The AM 721 system showed good agreement with routine flame photometry.
- It requires only a small sample size of 50 microliters.
- The system is ideal for urgent testing when a centrifuge is not available.
Takeaway
The AM 721 is a small and fast device that can measure important substances in blood and urine without needing a centrifuge.
Methodology
The study compared results from the AM 721 system with routine flame photometry for sodium and potassium measurements.
