Dried blood spot for Ebola testing in developing countries

Blood group testing in developing countries: an ignored concern.

Dried Blood Spot Sampling for Hepatitis B Virus Serology and Molecular Testing

BACKGROUND AIMS Dried blood spots (DBS) on filter paper have been successfully used to diagnose and monitor several infectious diseases. The aim was to investigate the performance of DBS in hepatitis B virus (HBV) diagnosis using commercial tests in comparison to standard methods. METHODS Paired DBS and plasma samples were collected from 200 patients: 100 patients with HBsAg negative status a...

Clinical evaluation of a dried blood spot assay for atazanavir.

Current procedures for obtaining and measuring plasma concentrations of HIV protease inhibitors (PIs) are technically challenging. Dried blood spot (DBS) assays offer a way to overcome many of the obstacles. We sought to develop a DBS assay for quantitation of the PI atazanavir (ATV) and to compare this method with a previously validated plasma assay. We prospectively enrolled 48 patients with ...

A digital microfluidic method for dried blood spot analysis.

Blood samples stored as dried blood spots (DBSs) are emerging as a useful sampling and storage vehicle for a wide range of applications. Unfortunately, the surging popularity of DBS samples has not yet been accompanied by an improvement in automated techniques for extraction and analysis. As a first step towards overcoming this challenge, we have developed a prototype microfluidic system for qu...
