question: Hello doctor, My son gets frequent nose bleeds and leg pain. The doctor tested him for Von Willebrand, all was normal except for the thromboplastin time. It was elevated to 36 normal is 22 to 34. His complements levels were elevated to ch 50 to 60, c3 178 normal is 80 to 170, CRP was 9 normal is >8, absolute eosinophils was 524, normal is 15 to 500. Is there any concern with these levels?
