I was curious cause we did something similar in school last year and the lab supplies were dirt cheap... $15 roughly for each of us. Was not the same test but they work in the same way.
For your defence if needed - the raw materials for your test as stated from the excerpt below probably cost them $45-$55 plus labour which is also minimal.
So they're asking you pay $1,700 for something that cost maybe $200 on the high side "including" labour.
PS - I just decided I'm moving to the US to start a biology lab of some sort! Live the high life...
The $45-$55 comes from the following:

Cost analysis
At CDHA (Halifax, NS, Canada), the average number of specimens submitted yearly for adenovirus testing is 312 (range 208 to 466 for years 2009 to 2012) and the turnaround time for virus culture can be up to 14 days. A cost analysis was performed that assumed a more practical approach of bi-weekly molecular testing (3–5 specimens with positive, negative and reagent controls). Excluding labor, the average cost of a commercial PCR following nucleic acid extraction would range from $45 to $55 (CAD) per specimen. In comparison, the in-house real-time PCR following a nucleic acid extraction would reduce the cost approximately ~2-fold ($21.44 to $25.97). Replacement of the nucleic acid extraction with the homogenization-base protocol further reduces the cost ~2-fold ($8.84 to $10.97), which is comparable to the average cost of virus culture ($9.47 to 11.64). The time require for bi-weekly processing for either molecular methods is ~5 h/week, which is far lower than the time required for weekly maintenance and processing of specimens using cell culture and DFA staining.
