RBC is an abbreviation for which blood component count?

• A. Red blood count
• B. Red blood cell count
• C. White blood count
• D. Platelet count

Answer: (A)

RBC refers to counting the cells that carry oxygen in the blood. The common way exam questions phrase this measurement is “red blood count,” which describes how many red blood cells are present in a given volume of blood. That makes this option the best match for what the abbreviation is indicating. The other choices point to different components (white blood cells or platelets) and don’t correspond to what RBC stands for in this context. While you’ll sometimes see the phrasing “red blood cell count” in formal writing, the idea the question is asking about is the count of red blood cells, i.e., the red blood count.
