Preparation:Fasting is not required. You may continue your regular daily medications and supplements. If possible, avoid taking any meds, supplements, IV infusions, or injections for 4 hours before your blood draw. If you’re on medications that affect white blood cells, collect an extra tube. Wait 2 weeks after finishing short-term meds like antibiotics before completing your blood draw.
