Covid 19 test

Hi. I'm hoping one of you lovely people may have any techniques or ideas on how you can do a covid test on your young person, who has a fear of choking, anything going up their nose and any bodily fluids? We have had a few scares this last couple weeks and it really worries me that my daughter refuses to have any tests done. I called the 119 and they were less than useless, they said to do a lateral flow test, i said that was the reason I was asking advice, as to which they hung up. I am so grateful for any advise. Many Thanks Vikki
