My PCP says my wbc count is 14. He is sending me to a hematology/oncology specialist. What is he looking for?

Evaluation. there are many things that can increase WBC from infection -which is the most common one, inflammation, to blood cancer etc. We are trying to help you to find the answer to why your WBC is elevated. the doc will ask u questions, examine you and get some blood tests to hopefully find the answer.
Rule stuff out. There are lots of possibilities. I can do this by taking a cold shower. There are some not-very-aggressive leukemias that can present this way at your age, and you'd best be seen.
