Free PCSIG Webinar

Acceptability and validity of microsampling for serosurveillance in Kenya


Free Webinar: Acceptability and validity of microsampling for serosurveillance in Kenya

July 17, 2024; 8am PT; 11am ET; 4pm BST; 5pm CET


We will present findings from a study assessing the acceptability, ease of use and validity of two microsampling techniques against venous blood sampling. This was a pilot study nested within a multi-pathogen serosurveillance project.
We set out to compare how well the Mitra™ microsampler and traditional Whatman DBS filter paper compare to gold standard venous blood draws. We assessed the acceptability among study participants and ease of use among sample collectors. Additionally, we aimed to determine the impact of different storage conditions and durations on antibody concentrations for vaccine-preventable diseases, such as, diphtheria, tetanus, pertussis, measles, mumps, rubella and varicella. Performance of the dried blood samples was compared against plasma derived from venous blood and testing performed using a Luminex multiplex assay.
