family ties lane是可以直接做完核酸回家等待结果的。这是指针对中国入境的旅客。
核酸还挺快的，下午做的，晚上就出结果了。

如果是social vistor申请ATP的话，那是要去指定酒店等待核酸结果。

Short-term visitors coming from these
countries/regions should consider applying for the Air
Travel Pass instead.

If approved to enter under the SC/PR Familial Ties
Lane, the following health measures apply:
No pre-departure test required
COVID-19 PCR test on arrival*, with self-isolation at
self-sourced accommodation or own place of
residence, until test results are released to traveller
