Complement levels high

[aracelik]

my son is 7 years old and every time they do blood work his complement 4 and ch50 are high. they even tested him when he was not sick and the levels are high. he complains of right leg pain at night also not every day though. should I be concerned? I went to a orth and he said it was growing pains bu I still dont know why his blood work is abnormal all the time.

my pediatrician said those levels are insignificant. but they want to send him to a rhemotoigist first. do you think he should go to a hematologist instead?he seems fine right now. but his blood work is always abnormal

Hi!
Complement 4 or C-4 is a protein that moves freely in blood and helps in inflammation. Usually this test is done to monitor response to management of autoimmune disease. C4 and other complements are high in rheumatoid arthritis and certain cancers. Also, CH50 levels are high in certain serious infections, cancers and ulcerative colitis. It is important to consult a hematologist. Take care!
