Retinol Analysis in Dried Blood Spots by HPLC [PDF]

The Journal of Nutrition, 2000
There are many advantages to measuring vitamin A in dried blood spots (DBS) from a finger prick as compared to plasma collected by venipuncture. The advantages include easier collection, transport and storage; accessibility to younger and more remote populations; and decreased risk of disease transmission.

Sorbent-less dried blood spot microsampling

Advances in Sample Preparation
Dried blood spots (DBSs) are typically sampled on porous sorbents, which may retain analytes in their structure during DBS rehydration but also release various species into the eluates and contaminate them.

Nontargeted Mass Spectrometry of Dried Blood Spots for Interrogation of the Human Circulating Metabolome [PDF]

, 2021
Advances in high resolution, nontargeted mass spectrometry allow for the simultaneous measure of thousands of metabolites in a single biosample. Application of these analytical approaches to population-scale human studies has been limited by the need for

Fluorimetric assay with a novel substrate for quantification of galactocerebrosidase activity in dried blood spot specimens

Practical Laboratory Medicine, 2020
Background: Decreased galactocerebrosidase (GALC) enzyme activity is causative for Krabbe disease, a lysosomal storage disorder with devastating neurodegenerative consequences. Quantitative fluorimetric assays for GALC activity in isolated blood and skin
