A few questions:

1) How many people get tested for STDs every day?

2) How many online medical/testing companies test for STDs without a
doctor's visit?

3) How long does it take to get results from these online companies?

4) How much does it cost (to the company) to send out samples to a lab
and get results back? (not the price to the consumer, rather the
pricing before markup)

You may do better if you repost each of these items as a separate
question. When questions are bundled together, many Researchers may be
leery of taking on the project, since a failure to find all the
requested information will mean that the Researcher will not be
compensated for any of his or her work.
