Which statement best compares commonly used laboratory tests for RSV?
1Antigen tests are always more sensitive than NAATs, including rRT-PCR, even for low viral loads, making them the preferred method for all diagnostic scenarios.
2NAATs such as rRT-PCR are generally highly sensitive; antigen tests are faster but usually less sensitive✓ 정답
3Culture gives an immediate result at bedside, similar to rapid antigen tests, and is widely used for screening in clinical settings.
4Serology is the only accepted acute diagnostic method, outperforming NAATs in early infection, and is recommended by all major health organizations.
해설
RSV NAATs are highly sensitive and can test upper or lower respiratory specimens. Antigen tests can be rapid but generally have lower sensitivity.
