My sister is 19 years old, past few days she had a headache and yesterday she had 2 episodes of vomiting. Dr. has asked to do blood test. In blood report wbc count is 17300 and platelets is 7.23. Lymphocyte is 6900 and granulocyte is 9300. So want to understand what could be cause of the parameters which are high. Dr. has asked to re take blood test. Please suggest. Are these are symptoms of bone marrow or cancer?
