Dried blood spot specimens for SARS-CoV-2 antibody testing: A multi-site, multi-assay comparison
PLoS ONE, 2021 The true severity of infection due to COVID-19 is under-represented because it is based on only those who are tested. Although nucleic acid amplifications tests (NAAT) are the gold standard for COVID-19 diagnostic testing, serological assays provide ...

Dried Blood Spot Test Estimation of Urea [PDF]
Annals of Clinical Biochemistry: International Journal of Laboratory Medicine, 1985 The analysis of urea in serum and whole blood samples dried onto filter paper has been investigated. In both cases the sample volume is not critical nor is the volume of sample applied to the filter paper if sample discs of consistent dimensions can be punched from the dried paper.

Iohexol plasma clearance simplified by dried blood spot testing [PDF]
Nephrology Dialysis Transplantation, 2017 Abstract Background Renal function can be estimated with formulas, which are inaccurate, or measured with gold standard methods, which are reliable but unpractical. We propose to simplify the plasma clearance of iohexol, a gold standard method to measure renal function, by dried blood spot (DBS)
