Which lab findings are often seen in patients with elevated LDH and low haptoglobin?

In the context of elevated lactate dehydrogenase (LDH) and low haptoglobin levels, increased bilirubin levels are commonly observed.

When there is hemolysis, or breakdown of red blood cells, the LDH levels rise because LDH is released during cell lysis. Concurrently, low haptoglobin occurs as it binds free hemoglobin released into the bloodstream from lysed erythrocytes, leading to its depletion. As hemoglobin is broken down, it is converted into bilirubin. This process results in an increase in unconjugated bilirubin levels, which is indicative of hemolytic anemia.

Thus, the combination of elevated LDH and low haptoglobin effectively points to hemolysis, which characteristically leads to increased bilirubin levels, making this the most appropriate choice among the options. Other lab findings like high platelet count or normal white blood cell count do not directly relate to hemolysis in the same context, and low creatinine levels are not typically influenced by these processes.
