The Good
Easy to follow procedure and easy to interpret results.
The Bad
Missing sample diluent in all three kits. Writing out the validation rules in mathematical formulas is slightly tricky (see image gallery for help).
The Bottom Line
This assay has high precision and accuracy with an easy-to-follow procedure. I would suggest checking the kit to make sure all reagents are present before beginning. Write out the validation criteria in a mathematical formula for automated validation.
