Which test is increased in acute infections?

In acute infections, the body’s inflammatory response typically raises white blood cell count with a left shift and increases acute-phase reactants, not the specific tests listed. The reticulocyte count reflects the bone marrow’s production of new red cells and rises with anemia, blood loss, or hemolysis—not infection. Osmotic fragility tests RBC membrane stability and is increased in certain membrane disorders, not due to acute infection. Blood culture is a diagnostic approach to detect bacteria in the blood, and its result is positive when organisms grow—not an inherent increase in a measured value during infection. Therefore, none of these tests are characteristically increased in acute infections.
