OSMT (Ontario Society of Medical Technologists) Practice Exam

Red cell indices include:

1. a. MCV, MCH, PCV

2. b. MCHC, RDW, MCH

3. c. MPV, RBC, RDW

4. d. HTC, WBC, HB

The correct answer is: b. MCHC, RDW, MCH

Red cell indices are specific measurements that provide important information about the physical characteristics of red blood cells. The correct answer includes MCHC (Mean Corpuscular Hemoglobin Concentration), RDW (Red Cell Distribution Width), and MCH (Mean Corpuscular Hemoglobin). - MCHC measures the average concentration of hemoglobin in red blood cells, giving insight into the cell's color and oxygen-carrying capacity. - RDW assesses the variation in red blood cell size, which can help identify different types of anemia or other hematological disorders. - MCH quantifies the average amount of hemoglobin per red blood cell, providing additional information on the red cell's ability to transport oxygen. Each of these indices is vital for diagnosing various anemias and other blood-related conditions, making them essential components of a complete blood count (CBC). Other options include components that are not considered standard red cell indices or encompass measurements that pertain to different blood components. For example, PCV (packed cell volume) and HTC (hematocrit) refer to the volume percentage of red blood cells in blood but do not fall under the specific "indices" category. MPV is related to platelets rather than red blood cells, and WBC refers to white
