The tutorial discusses a pregnancy test procedure using two droppers containing different urine samples. The top dropper contains the urine of a pregnant individual, which has HCG, while the bottom dropper contains the urine of their husband, which should not have HCG. Three drops of each urine sample are added to their respective tests, and the results are left to process for three minutes. It's important not to read the results after five minutes, as they become invalid. After three minutes, both tests show a line in the control areas, confirming that enough urine was added and the tests are functioning correctly, with particular focus on interpreting the pregnancy test result.
