What is hemolysis and why is it problematic for lab results?

Hemolysis is the rupture of red blood cells, which releases intracellular contents into the plasma or serum. This matters because those substances, especially potassium and LDH, spill into the sample and can cause falsely elevated values and distort many test results. Free hemoglobin and cell debris also interfere with photometric and enzymatic assays, leading to inaccurate measurements or sample rejection. The other options describe infection, dehydration, or contamination, which are not about red cell rupture. Because a hemolyzed specimen can mislead results, labs often recollect the sample if hemolysis is present.
