Hypothesis
The trial aimed to assess the performance of two designs of solid state colorimeters in various climatic conditions.
Conclusion
The trials indicated a need for two distinct colorimeters for different healthcare settings.
Supporting Evidence
- The MonA colorimeter provided better precision than traditional methods in areas with unstable electricity.
- Field trials were conducted in The Gambia and Nepal to gather additional data on the MonA colorimeter.
- Both colorimeters were designed to operate without conventional filters, using LED technology.
Takeaway
This study tested two types of colorimeters to see how well they work in different places, and found that we need two different kinds for different uses.
Methodology
Field tests were conducted in various climatic conditions using two types of colorimeters to measure haemoglobin levels.
Limitations
The trial was terminated early, and some instruments had issues with visibility and calibration under certain conditions.
