Urine Sample Pot

Hello,

i have an appointment with the urologist tomorrow.

When I went to the Dr last week, I took a urine sample with me. (Happened to have a sealed urine pot in the bathroom cupboard for some reason)

I'm wondering if I should take a sample to the Urolgist with me tomorrow? But I don't have another sterile pot .. Anyone know if I could get one from a pharmacist?

thanks
