To prepare for a blood test evaluating white blood cells, follow these tips for accurate results. Fast if instructed, typically for 8-12 hours, drinking only water. Inform your doctor about medications, including ceftriaxone injections, as they may affect white blood cell counts. Avoid strenuous exercise 24 hours prior, as it can elevate levels. Stay hydrated to ensure easy blood draw. Refrain from smoking or alcohol, which may skew results. Arrive well-rested, as stress or fatigue can impact counts. Follow any specific instructions from your healthcare provider to ensure the test reflects your true health status.
