I stupidly did this yesterday.
Presented my code with DH's test. Only realised after it was scanned.
The stewards said to just scan my test against DH's and it would be fine as we would know we have each other's result when they come.
Has anyone else done this? Could it be amended retrospectively if Test & Trace call?
I'm expecting a positive (symptoms and positive LFT), whereas DH had a negative LFT and had no symptoms.
