A member asked:

How do home pregnancy tests work? where you urinate on the stick. how is it able to determine if you're pregnant from your urine?

A doctor has provided 1 answer

Preg test: It detects the pregnancy hormone hcg. However, it may not detect low levels of this hormone very well, so you should have a confirmatory blood beta HCG level in your doctors office.
