Primary Institution: St. James's University Hospital
Hypothesis
The study aims to improve the efficiency of urine analysis by modifying the Chemispek analyzer.
Conclusion
The modified Chemispek analyzer allows for rapid urine analysis with direct print-out of results, significantly reducing analysis time and costs.
Supporting Evidence
- The modified analyzer has been in trouble-free operation for several months.
- The analysis time has been halved, and there are no initial manual dilutions required.
- The reagent costs are less than 10% of those for the Astra-4.
Takeaway
This study shows how a new way to test urine can make it faster and cheaper to get results.
Methodology
The study involved modifying the Chemispek analyzer to allow simultaneous measurement of sodium and potassium without pre-dilution of urine samples.
