Welcome to the forum, and aloha. (This reply originates from my place at Poipu Beach, Kaua'i.) Directly to your questions.
1) It is correct that more recent research has suggested a higher proportion of false negatives with rapid testing than previously realized. My recollection is that it's around 15%, i.e. meaning a negative result remains at least 85% reliable. However, the newer studies were rather small, and there is a large margin of error. To my knowledge the exact reasons are not known. However, false negative results do not occur repeatedly in the same person; so two negative results with rapid tests is virtually 100% reliable.
2) The window period ("time line") is about the same for the lab-based and rapid tests. 8 weeks usually is conclusive.

早期85%的准确率。但8周就和联酶差不多了。(好象仙翁也是这个观点,向仙翁致敬) |
