CORRELIA BIOSYSTEMS, INC. — Department of Health and Human Services SBIR Phase I: NHLBI

Description

DESCRIPTION provided by applicant This phase I SBIR proposal describes the development of an electrokinetic lateral flow test eLFT for diagnosing sickle cell disease and trait at the point of care This technology will be developed to work in low resource settings where the long term goal is implementing low cost neo natal screening programs that can have an immediate impact on preventing childhood mortality which reaches upwards of for children born with SCD in sub Saharan Africa The sickle cell disease eLFT technology is based on a patented sandwich immunoassay format on a next generation lateral flow test platform actuated by a low power battery for portable and rapid detection The test will result in high specificity detection of adult hemoglobin HbA sickle hemoglobin HbS or a combination of the two from whole blood providing a simple readout corresponding to the patient being negative for sickle cell disease detect HbA only positive for sickle cell disease detect HbS only or positive for sickle cell trait detect HbA and HbS The following specific aims will be achieved during the development of the eLFT diagnostic production and screening of high quality monoclonal antibodies differentiating HbA from HbS optimization of the core eLFT microfluidic chip design and assay protocol development of a portable chip reader and testing of diagnostic sensitivity and specificity of the final device Collaboration with the Sickl Cell Foundation of Ghana will inform design and future clinical testing requirements Phase II to ensure that the eLFT device is suitable for point of care operation in low resource settings including clinics in the developing world PUBLIC HEALTH RELEVANCE The goal of this project is to develop an affordable rapid and accurate test for sickle cell disease and sickle cell trait The test will be designed for use at te point of care in low resource settings at significantly lower cost than current alternatives The research outcome will help to increase the capability for implementing newborn sickle cell screening programs that can significantly reduce childhood mortality and healthcare burden in many countries End of Abstract
