What teenage books series was this?

The book series I am looking for is about a teenage girl. She finds out that she can heal really fast and has some other abilities. It turns out she and a few others were created in the lab. They all look similar. I believe she has silver blood, but I am not certain. I just know that she is slowly discovering her past and finds more teenagers like herself.What teenage books series was this?
