Antibody tests in Santa Clara County show that 2.5% and 4.2% have them, yet tests of front line Wuhan responders show just 2-3%. Are these antibody tests reliable?

They clearly show higher immune rate in a lower impact community. The numbers are very low in either case to hope for herd immunity

Serology testing from Wuhan indicates only 2-3% have antibody among 8,600 hospital workers and visitors, with much more testing in the works t.co/ujYD4ZnE29

• The researchers asked more than 3,000 people to volunteer for antibody testing.
• The results indicated that between 48,000 and 81,000 people could have been infected with Covid-19 in Santa Clara County.
• That’s far higher than the official numbers.
