Will I have to isolate?

[RosieLemonade]

If I last saw someone in my bubble on Friday and they have taken a test for a fever today. Will my isolation start from the last time I saw them or from when they took the test?

Isn't that long enough ago not to need to isolate?

People who were in contact 2 days before symptoms started need to isolate.
If symptoms only started today and you last saw them Friday you won’t have to.

Everyone who lives with them will need to isolate until results are back though - and then ten days from symptom start if positive.
