6yrold complains of joint/leg/stomach pain infrequently.hes otherwise healthy.could a full blood test rule out leukemia?do growing pains last month's?

Common complaints: Yes, leukemia can present with symptoms of bone pain, but would rapidly progress to fatigue from anemia or bruising from low platelets. A normal blood test would r/o leukemia but formal diagnosis would be a bone marrow test. Intermittent symptoms of joint pains over many months are common in kids and reassuring if they come and go. Kids get bruises on shins, etc., but rare on abdomen,
