What is a key feature of the pregnancy test process?

The key feature of the pregnancy test process is that it has a step involving urine carrying blue beads. Most home pregnancy tests are designed to detect the hormone human chorionic gonadotropin (hCG) in urine, which is produced soon after a fertilized egg attaches to the lining of the uterus. The test typically involves a strip or stick that reacts when urine is applied. In certain types of tests, a colored indicator, such as blue beads or dye, is used to show a positive result when hCG is present. This visual change indicates a pregnancy.

The other techniques mentioned, such as requiring a blood sample or using two different sticks, are not standard for most home pregnancy tests, making them less relevant in this context. Moreover, results are usually available within a few minutes, rather than after a prolonged period like 24 hours. This rapid response is a significant feature that highlights the efficiency of home pregnancy testing.
