Ca-a-19 is a test that I am not familar with so I reached out to an MD friend of mine to see what he said. So from what I understand, this is not a test that just any doctor normally does. Usually it would be a test that a specialist would request and it is usually reserved for people that have cancer that are tracking their progress. He said that, like many other labs, this is used to look for trends when observing cancer. So that leads me to a question for you. If you would like to talk about this further, pplease write anohter question back and remind me of this conversation so I know who you are when I read it. So seeing that this is a test used to track cancer, do you have cancer? That is the only reason the Doctor can think of as to why this would have been requested. And as far as Clomid being responsible for increase, he said he does not believe that it could have made the number go up. 

If you do have cancer, you really dont want to mess with AAS especially at high doses. Gear can lead to high estrogen. Cancer often times loves estrogen and it helps it to grow. So this is my main concern for you. Write back again and give me some more details.
