Hi @twachter, and welcome to Mayo Clinic Connect! I am so glad you came here to visit with others about your post-surgery healing. You have to be stressed not being able to find a clear answer to your concerns.

First, understand I am absolutely not a medically trained person. I am a Mayo Clinic MN patient who is navigating my own health journey. I tried to search for “ Reticulocyte Haptoglobin” from the home page and didn’t find other discussions. There are some member comments including them individually, and you may want to try searching yourself (if you haven’t already).

I checked what Mayo Clinic Labs has to say about these tests and it sounds like it is reasonable to expect you learn more by retesting after a couple weeks following initiation of treatment. I guess if it were me, I would go back to my PCP who has identified a concern and ordered your treatment. It will help her to know what your cardiologist told you and ask what she recommends. In the meantime, definitely continue reporting to your cardiologist how recovery is going.

Other members may have more personal experience and expertise.

How are you feeling? Are you taking the iron and B12 your PCP recommended, and do you have a plan to follow up with her?
