These companies are NOT the same:
Alltest
Biotest / Premier Biotech. The manufacturer's numbers for the test can be found here (which were used in the study).
Quote:Also of note, the actual manufacturer of the serology tests is a Chinese company that is actually now banned from exporting tests to the US. Hangzhou Biotest Biotech. Sounds like a reputable entity......
As of April 1, manufacturers were no longer allowed to export COVID-19 tests unless they have been approved by the China equivalent of the FDA. This test has not yet had that approval, so it can no longer be exported. Shipments were allowed prior to that date. The use of the word "banned" suggests something nefarious, but I don't think that's the way to portray this. (An NBC report mis-characterized the situation, per Biotest Biotech)
