We need to nail down some terminology so's we can separate the apples from the oranges as Injineer Bob is suggesting.
Finding moisture on the surface of your concrete SOG would be consistent with condensation. That can occur only if the surface of the concrete is at or below the dew-point temperature of the air inside the room in question. That would not be a slab problem, even though you indicate your slab was not properly prepared before placement.
A second source of liquid moisture at the slab surface could be from hydrostatic pressure forcing liquid moisture to the surface. That would be a very serious problem and would eliminate the successful installation of most any floor covering. Treatment of that kinda problem would involve landscaping and other exterior considerations.
Third, and not at all likely to result in liquid moisture appearing on the surface under the conditions you describe would be moisture vapor transmission from below. You will almost certainly have some of that due to your lack of a vapor barrier under the concrete. The extent of it is what Bob's test will help you determine. This condition should be more evident when the interior of the structure is being cooled artificially, though, and the results might be misleading unless conducted during those conditions. But if such a test does indicate vapor transmission when the interior is also warm and moist, you can expect a much more dramatic indication when the room is cool and dry.
What you need to determine is which of these things is makin' the wet spots, eh?
My opinion; worth price charged.
