Tony's Tech Tip: What does LOQ stand for and why is it important?

LOQ stands for limit of quantitation and every particular test method has one.

Generally, it's defined as the first nonzero control in the standard curve. Anything above that level can be accurately and reproducibly measured and quantified; however, anything below that level should simply be reported as below limit of quantitation.

This is not to be confused with the LOD, or limit of detection, which defines the background noise of a particular test method.
