We have a friend who is pregnant. She is currently at 8 weeks but her OB doctor said her levels are only reading at about 3 weeks. After our first visit to the ER during our miscarriage in February, I did some research into these charts and how to read them since the ER odctors would tell us nothing. I wanted to find the numbers again to try and help our friend understand what is going on. This link is an hCG Blood Level sheet from the INCIID - or International Council on Infertility Dissemination As the ER doctors told us during our miscarriage, the numbers are not as important as the direction of the numbers, but what the chart does seem to demonstrate after one test, is the direction is down. We are praying for our friend that is not the case. We know first hand the saddness of a miscarriage.
