SARS-CoV-2 RNAemia uncommon in blood donors


According to a study published online May 27 in plasma minipools (MP) nucleic acid testing from donors, severe acute respiratory syndrome of coronavirus 2 (SARS-CoV-2) RNAemia is reported to be uncommon . Transfusion.

Sonia Bakkour, Ph.D., of the Vitalant Research Institute in San Francisco, and her colleagues tested collected from March 7 to September 25, 2020 for SARS-CoV-2 RNA (vRNA) in plasma MP donor from six or 16 donations. To love , reactive MPs were tested by transcription-mediated amplification after serial dilution.

Overall, 17,995 MPs were tested for approximately 258,000 vRNA donations. The researchers identified three confirmed reactive MP16s, with an estimated prevalence of 1.16 / 100,000 vRNA reactive donations. VRNA-reactive samples were not antibody-reactive; within each MP, the estimated viral loads of positive (presumably unique) donations ranged from

“Other studies have shown that in rare cases where a blood sample tested positive, blood transfusion transmission has not occurred,” Bakkour said in a statement. “Therefore, it seems safe to receive blood as a transfusion recipient and continue to donate blood, without fear of transmitting COVID-19 as long as current projections are used.”
