My DB's had what he thought was a mild cold since Friday, no temperature or cough. He works from home and hasn't been out all week.
He took a LFT last night and again this morning and both were positive so has ordered a PCR (he can't get to a testing station). Assuming it's positive, will his ten days isolation start from when he gets the PCR result, or from the time of the first LFT or from Friday when his (cold) symptoms started?
