Hypothesis
The microprocessor-based colorimeter will provide accurate blood analysis results comparable to a commercial instrument.
Conclusion
The microprocessor-based colorimeter shows precision and reproducibility comparable to commercial instruments.
Supporting Evidence
- The colorimeter uses LEDs and an 8085A microprocessor for analysis.
- Good correlation was found between the results from the microprocessor-based colorimeter and the Spectronic 21.
- The instrument achieved photometric stability after 10 minutes.
Takeaway
The new colorimeter can test blood samples and gives results that are just as good as the expensive machines.
Methodology
Blood samples were analyzed for urea, glucose, total protein, albumin, and bilirubin using the microprocessor-based colorimeter and results were compared with a Spectronic 21.
