The Good
The standard curve is nicely spread, without huge gaps between points. Easy to follow protocol with repeatable results.
The Bad
Sample values that fall on the high or low-end of the curve fall out of range easily.
The Bottom Line
This is a good product that offers an easy-to-follow protocol that is user friendly. It can be applied to quantifying dried blood spot levels and not just whole blood or serum. Standard 0 works the best for diluting patient samples or the standards.
