Stressing - am I wrong?

Hey everyone

I just had an active stand test for POTs. The results were inconclusive as my testing was higher because of the GP setting but… am I going insane or is it supposed to be 10 minutes total standing?

I was under the impression you stand up for 10 minutes, with readings taken at 2,5, and 10 minutes.

Instead she did the test as a 2 minute timer, then a 5 minute timer, then a 10 minute timer. So total of 17 minutes.

I tried saying that I was confused and thought the GP said it was 10 minutes cumulative, not 17, but she insisted that wasn’t the case.

Was I wrong? I’m very confused and tired aha
