See full answer•The FDA provided an update on one potential treatment called convalescent plasma and is encouraging those who have recovered from COVID-19 to donate plasma to help others fight this disease. Convalescent plasma is an antibody-rich product made from blood donated by people who have recovered f from the disease caused by the virus. The agency launched a new webpage to guide recovered COVID-19 patients to local blood or plasma collection centers to discuss their eligibility and potentially schedule an appointment to donate. The webpage also includes information for those interested in participating in the expanded access protocol, conducting clinical trials, or submitting single patient emergency investigational new drug applications.Apr 16, 2020
Respiratory viruses, in general, are not known to be transmitted by blood transfusion. There have been no reported cases of transfusion-transmitted coronavirus, including SARS-CoV-2, worldwide.Jan 11, 2022
At this time, the FDA does not recommend using laboratory tests to screen blood. Someone who has symptoms of COVID-19, including fever, cough, and shortness of breath, is not healthy enough to donate blood.Standard screening processes already in place will mean that someone with these symptoms will not be allowed to donate.Jan 7, 2022
The blood from people who recover from COVID-19 contains substances called antibodies, which are capable of fighting the virus that causes the illness. For some other diseases caused by respiratory viruses, giving people the liquid portion of blood that contains these antibodies, called plasma, obtained from those who have recovered from the virus, may lead to more rapid improvement of the disease. Patients with COVID-19 may improve faster if they receive plasma from those who have recovered from COVID-19, because it may have the ability to fight the virus that causes COVID-19.Dec 28, 2021
COVID-19 virus has been detected in blood and stool, as had the coronaviruses responsible for SARS and MERS (14,16,19-21). The duration and frequency of shedding of COVID-19 virus in stool and potentially in urine is unknown.Mar 2, 2020
There is currently no evidence that the COVID-19 virus is transmitted through semen or vaginal fluids, but the virus has been detected in the semen of people who have or are recovering from the virus. Further research is needed to determine if the COVID-19 virus could be transmitted sexually.

Blood samples are only used to test for antibodies and not to diagnose COVID-19. Venous blood samples are typically collected at a doctor's office or clinic. Some antibody tests use blood from a finger stick.Feb 2, 2022
No evidence to support that COVID-19 risk can be determined by ABO blood group. The researchers say that overall, the review findings suggest that there is no actual relationship between ABO blood type and SARS-CoV-2 infection or COVID-19 severity or mortality.Apr 26, 2021
COVID-19 convalescent plasma, also known as “survivor’s plasma,” is blood plasma derived from patients who have recovered from COVID-19.Aug 18, 2021
Monoclonal antibodies are laboratory-made proteins that mimic the immune system's ability to fight off harmful pathogens such as viruses, like SARS-CoV-2. And like other infectious organisms, SARS-CoV-2 can mutate over time, resulting in certain treatments not working against certain variants such as omicron.Jan 24, 2022
If you were treated for COVID-19 with monoclonal antibodies or convalescent plasma, you should wait 90 days before getting a COVID-19 vaccine. Talk to your doctor if you are unsure what treatments you received or if you have more questions about getting a COVID-19 vaccine.
