What is the most common point-of-care testing (POCT)?

• A. Hematology analyzer
• B. Blood glucose monitoring
• C. Lipid panel
• D. Troponin assay

Answer: (B)

Blood glucose monitoring is the most common point-of-care test because monitoring blood sugar is essential for managing diabetes in almost every setting—at home, in clinics, and at the bedside in hospitals. Glucose meters are inexpensive, simple to use, and require only a tiny finger-prick sample, delivering results in minutes. This rapid, widespread capability allows immediate decisions about insulin dosing, treatment adjustments, or dietary changes, which explains why glucose testing has become the most prevalent POCT.

Other tests like hematology panels, lipid profiles, and troponin assays do have point-of-care versions, but they generally involve more complex equipment, higher costs, or more specialized clinical needs, so they aren’t as universally adopted as routine blood glucose monitoring.
