Abstract From COVID pandemic spread until now, many HSCT unrelated donor registries recommend as a precaution a systematic COVID‐19 testing for all donors during the precollection time. Literature is quite poor to support this systematic attitude. We report one sibling allogeneic HSCT which we proceeded despite a positive COVID test on related asymptomatic donor and summarize the all seven cases reported until now. We suggest to question this systematic COVID testing, two years after pandemic began, when there is no systematic testing on other blood products received during all the haematological malignancies treatment process.
