Hello, I am concerned about my 15 year old daughter, she bacame very ill about two weeks ago, there was vomitting, fever (103 or Higher), her body broke out in a rash, there was abdo. pain. I took her to ER they ran many test and could not come up with what was wrong. Last week i took her to her family doctor and he said that she had a high blood platlets, and that, elevated white blood count, they tested her for Hep. they all came back negative, thank God. She now have to see a blood specialist, should I be concerned.
