Hemolysis of Blood Samples

Hemolysis of Blood Samples

Hemolysis of Blood Samples, Hemolysis is the breakdown of red blood cells, which can affect laboratory results. Serum samples containing more than 100 mg/dL of hemoglobin can cause non-specific binding in serologic tests. Therefore, serologic testing is not recommended for a serum sample containing more than this amount of hemoglobin.

Follow the instructions below for this:

  • Before taking the blood sample, check that the syringe and needle are dry. Also, the barrel and cage of the syringe fit correctly.
  • Never use a 24 or 26-gauge needle.
  • Do not draw the blood sample too quickly, especially do not foam the blood.
  • When transferring blood from the syringe to the tube, remove the needle from the syringe and carefully slowly insert it into the tube.
  • Do not shake the tube too vigorously to mix the anticoagulant, but mix carefully and slowly.
  • The test tube should be dry and clean.
  • If the test tube containing the sample is kept in the refrigerator, never put it in the freezer.
