Quizplus · Accepted Answer

Osmotic fragility testing is commonly used to diagnose hemolytic anemia, as it measures the ability of red blood cells to withstand changes in osmotic pressure. In hemolytic anemia, the red blood cells are more fragile and prone to breaking open, leading to pallor and fatigue. Choice B, osteocalcin, is a marker of bone metabolism and is not directly related to hemolytic anemia. Choice C, oxalate, is a substance that can cause kidney stones and is not directly related to hemolytic anemia. Choice D, osmolality, measures the concentration of solutes in the blood and is not a specific test for diagnosing hemolytic anemia.
