Comparative Studies (VAMS vs Wet Samples in Human)

Analyte	Patient or Animal Group	Sample Collection	Outcome of the Study	Reference
Emixustat	Human	Finger stick and venous blood samples	The validated assay allows for the comparison of data from both finger stick and venous blood samples absorbed onto VAMS devices to simultaneously collected traditional plasma samples.	44
Cathinone analogues	Six healthy volunteers		The bias values observed between dried VAMS samples and comparison validated methods on wet samples were satisfactory for all the dried matrices, thus demonstrating a good equivalence.	18
Homogentisic acid (HGA), Tyrosine (TYR), Phenylanaline (PHA)	AKU patient urine obtained from surplus anonymized samples retained		Dried VAMS and liquid samples compared well	48
