A member asked:

How is it proven that hcg levels (in pregnancy) double every 2 days?

A doctor has provided 1 answer

Check levels: You can easily check these values on blood work as well to coordinate such labs with our understanding of placental physiology and development. Not sure why u want to know but i hope this answers your question.
