Turns out there isn’t a super clinic near me that opens at 7 :( But the tip is much appreciated. The Melb Pathology places closer to work (and me) are open at 8 which would work better logistically.

I think the time I had to pay was because it was an ECG and I went to a pathology clinic at a hospital and billing was all convoluted and confusing. Looks like it should be ok with a standard blood test.
