So how to recognize if the laboratory is actually testing the products on the declared number of people? Now I’m checking whether the company is actually recruiting large number of volunteers (e.g. on Facebook). I’m also trying to compare whether the total payment they offer to the testers is not bigger than the price of such a test for the company. Suppose a laboratory pays volunteer 90 USD for a test, and the price of such a test is 3,300 USD on 30 subjects. Sounds “normal”? How much should such a test cost? It’s a in-use test under the supervision of a dermatologist.
Paying $90 for 30 subjects = $2700 just in subject fees. So, the extra $600 is their gross. Subtract business expenses, eg salaries of the people doing the test, rental of the office, any fee to the dermatologist. That is a razor thin margin right there.
I would expect that should be more like $5400 but perhaps I’m missing something.
