Here’s a clear look at good serum vs. hemolyzed serum and why hemolysis matters.
🔸 Good serum (left): Yellowish, clear, and ready for testing
🔸 Hemolyzed serum (right): Red-tinted because red blood cells have broken open and mixed into the serum
Hemolyzed samples can interfere with certain assays and may lead to inaccurate results.
Winter shipping tip:
Even in cold weather, always use an ice pack — but keep it insulated and away from the tubes to avoid freezing and hemolysis.
