My current plan (if I do leave China to go to the US) is to fly from the US to Taiwan first, endure quarantine, and stay for a couple of weeks. Then I'll fly to Shanghai and endure more quarantine. TW quarantine is 10 days now and I can get a place with a yard so that'll be bearable. Also flying from TW I won't need to get blood drawn or get an antigen test. Just a PCR test.
You might be a bit confused. The blood test is to check for antibodies (as a result of vaccination or a previous infection, presumably), PCR and antigen tests typically (but not always) use a nasal swab, with the PCR test being more expensive, often slower, and generally more accurate.
