A patient arrives at the clinic for a FBS. He tells you he just ate his breakfast. What is your best course of action?

If a patient arrives for a fasting blood sugar (FBS) test after having eaten breakfast, the best course of action is to inform the patient that the test cannot be accurately performed under these conditions. You should advise him to return for the FBS test after an appropriate fasting period, typically 8-12 hours. In the meantime, you can discuss other aspects of his health or schedule a follow-up appointment.
