Testing UGL HCG

Hi, I’m not sure this was ever answered. Can I and how do I test UGL HCG to make sure it actually has HCG in it? I’ve seen some mentions of using a pregnancy test but not the actual process. Will this work? How many IUs do I have to squirt on the test strip or do I mix some with water first to get a greater volume of liquid and not waste too much in the testing?

Thanks
