Hypothesis
The study investigates the effectiveness of an automated system for measuring zinc and copper levels in plasma.
Conclusion
The automated assay method for plasma zinc and copper is effective and can be implemented in most laboratories.
Supporting Evidence
- The recovery rates for copper and zinc were 99% and 95%, respectively.
- Within-batch precision for the assays was below 3%.
- Significant increases in plasma zinc concentrations were observed in samples stored at room temperature.
Takeaway
This study shows a new way to measure zinc and copper in blood that is easier and faster for doctors to use.
Methodology
The study used an automated continuous-flow system for the assay of zinc and copper in plasma, with various quality control measures.
Potential Biases
Potential contamination from haemolysis and variability in sample handling could introduce bias.
Limitations
The study's findings may be influenced by sample storage conditions and the timing of blood collection.
Participant Demographics
Participants included healthy subjects and patients from an antenatal clinic.
