Hi Jane and welcome to the forum.

The length of time you have to wait for results can differ depending on what part of the country you're in but there may also be delay at the moment due to the Covid-19 situation.

If you're concerned then don't be afraid of getting in touch with them to double check. You could try getting in touch with your dad's GP to let them know about the change in his health and see if there is anything they could do to speed up the process as well.

Fingers crossed the results come back quicker than expected.

Best wishes to you both,
