The global spread of COVID-19 has created a greater need for blood and plasma donations for those who regularly rely on blood products. In addition, convalescent plasma is now being used to develop serums recently approved for clinical trials by the U.S. Food and Drug Administration (FDA) in helping prevent the spread of COVID-19.

eDHQ Lite application for hospitals and blood donation facilities gives donors a way to save time by filling out their required health questionnaire at home electronically, before going to give blood, minimizing donors’ physical contact with surfaces to help reduce their risk of exposure.

The Signup is a Breeze!

eDHQ Lite facilitates donors filling Donor History Questionnaire from anywhere, present an encrypted barcode on a paper or in a mobile device to the collection centers on day of donation. eDHQ Lite does not perform any data validation or donor or donation eligibility checking. It merely allows a dhq form to be filled online in the privacy and comfort of the donor’s home, allowing social distancing, required in current pandemic environment. Our eDHQ Lite site can be used for any kind of Form Filling e.g. Convalescent Plasma Donation, Plasma Donations and Blood and Platelet Donations, Surveys and Research. It is on a first-come-first-served basis.
