Here's every technique and protocol you need to prevent it -and what to do when it happens anyway.","\n\u003Cp class=\"lead\">Hemolyzed specimens are the single most common cause of specimen rejection in clinical laboratories. A hemolyzed sample means red blood cells have ruptured and released hemoglobin into the serum or plasma, contaminating the specimen and rendering many tests unreliable.

When the order requires SST and you have a viable AC vein, use a 21G straight needle.
