  • EDTA tubes
  • Tubes containing glycolytic inhibitors such as those with gray closures

To mitigate hemolysis, employing partial vacuum tubes is recommended as they facilitate a gentler rate of blood transfer into the tube. Furthermore, syringes offer additional control over the vacuum, minimizing the risk of cell damage.

In cases where tubes deviate from the standard order, phlebotomists must remain mindful of the potential for additive carryover affecting subsequent samples. Employing appropriate strategies to address this risk is essential for maintaining sample integrity.

Handling and Processing Specimens

Proper handling and processing of blood specimens is vital in preventing hemolysis. Here are some guidelines to follow:

  • Handle blood specimens gently and mix them promptly after collection.
  • Invert the blood collection tube as indicated by the manufacturer and let clot formation occur at room temperature before centrifugation to ensure the integrity of the sample.
  • Use a needle and syringe or winged needle set carefully to fill tubes without applying additional pressure that can cause the red blood cells to hemolyze.

Following these guidelines will help prevent hemolysis and ensure accurate test results.

During blood sample processing, it’s essential to:

  • Avoid rimming clots as it may rupture red blood cells and cause hemolysis
  • Fill blood collection tubes to their designated fill level to prevent the anticoagulant concentrations from becoming too high, which could damage red blood cells
  • Warm the skin puncture site beforehand to minimize the need for excessive squeezing during blood collection, which is a common cause of hemolysis.

Properly packaging blood specimens with ample cushioning and shipping them in an insulated container with a cold pack is vital to prevent hemolysis while the samples are in transit. Transferring blood from a syringe to a blood tube requires careful attention to avoid needlestick injuries, contamination, and possible increased hemolysis.
