Yes and no. Both have a place and enormous potential still to go.

Antigen tests are best performed in labs to reduce false positives (for now). There are 'rapid' antigen tests with faster response times but the accuracy rate is still not anywhere past 90% reliably enough - still evolving. And none produced with a 100% accuracy test strip yet for portable device....but no doubt in the works.

Antibodies lab + rapid device tests have already achieved 100% accuracy potential (if there are enough antibodies in the host).

For post-vaccine tests, antibodies are best to check its working..possibly repeatedly to ensure immunity remains.

until a successful vaccine & reaches majority globally (ie: years for >90% like polio, TB etc), pretty much every test type is neccessary considering the global demand for constant testing - whether lab or portable.
