The Good
Excellent curve with high accuracy and precision. Easy to follow procedure with repeatable results.
The Bad
No set diluent (use the 0 standard), PBS results in slightly high CV issues.
The Bottom Line
This was used to quantify the levels of TSH in dried blood spots. The result values are repeatable, though accuracy is sacrificed slightly with the high dilution required to elute the sample from the paper card. Overall, this is an excellent kit that gave no issues in the validation process.
