If you had low levels of oil, the coolant would be very cloudy and look like hot chocolate. Higher concentrations would separate out in the tank and form a layer. You do not need a lab for that.............

As far as identifying the brand, I don not know of any lab that can do that. If you are unsure of the quality of the mix in the car, drain it and refill it with fresh OEM coolant and distilled water.
