That seems correct to me. I tried to look up the costs in Australia and I think this is the Medicare Benefits Schedule for it (ie C-reactive protein), though I'm happy to be corrected if I'm wrong:

If correct, it seems the cost to the taxpayer is $9.70 AUD (about $6.67 US). So even without bulk-billing making it free here, that's still a 10x markup.
