Definition & Operational Usage
Capillary blood glucose testing involves obtaining a small blood sample from a fingertip or alternate site to measure blood glucose levels using a portable glucometer. This point-of-care test is commonly performed by firefighter/medics to assess patients with altered mental status, suspected hypoglycemia, or diabetic emergencies. Not to be confused with laboratory venous blood glucose analysis, capillary testing provides immediate results critical for prehospital decision-making and treatment under protocols like NIMS (National Incident Management System).
