The phrase “how often is WBC” can mean two different things, so here are both, clearly:

1. How often is the WBC blood test done?

WBC (white blood cell) count is part of a CBC (complete blood count), and there isn’t a single fixed schedule; it depends on why it’s being checked.

In hospitals or during acute illness

  • During a serious infection, after surgery, or during chemotherapy, doctors may check WBC every few days or even daily to monitor response and watch for complications.
  • This closer monitoring continues until things stabilize (infection improving, recovery progressing, or treatment adjusted).

For generally healthy people

  • If you’re healthy with no symptoms, a WBC is usually checked only as part of a routine blood panel , often about every 1–2 years , or whenever you have a general health check your doctor orders.
  • Many people may go longer without a WBC test unless a specific issue (like fatigue, repeated infections, or other symptoms) appears.

For chronic conditions or certain medications

  • If you have conditions that affect bone marrow or immunity, or you’re on medicines that can lower WBC (for example some chemotherapy or immunosuppressants), WBC may be checked every few weeks to every few months , depending on the treatment plan.

In short: WBC isn’t on a fixed calendar; it’s done as often as your situation requires—rarely for healthy people, very frequently for those under active treatment.

2. How often is the “WBC” boxing tournament?

If you meant World Boxing Council (WBC) in the boxing sense (for example, “How often is the WBC title fought for?”):

  • WBC is a sanctioning body, not a single event, so there isn’t one “WBC event” per year.
  • Each WBC title (like WBC heavyweight, WBC welterweight, etc.) is defended whenever a champion and challenger agree and regulators approve , often around 1–2 times per year per champion , but this varies by fighter, injuries, and negotiations.

Quick pointers for you

  • If you meant your lab result :
    • Ask your doctor: “How often should my CBC/WBC be checked for my condition?”
    • Frequency depends heavily on your diagnosis, medications, and recent results.
  • If you meant boxing :
    • Each WBC world champion typically defends their belt roughly once or twice a year, but there is no strict schedule across all weight classes.

If you tell me which one you meant (blood test vs boxing), I can tailor a short, specific explanation or even a sample question you can ask your doctor or trainer.
