Hemolysis resulting from phlebotomy may be caused by incorrect needle size, improper tube mixing, incorrect filling of tubes, excessive suction, prolonged tourniquet, and difficult collection.
What are the common causes of hemolysis?
Hemolysis inside the body can be caused by a large number of medical conditions, including many Gram-positive bacteria (e.g., Streptococcus, Enterococcus, and Staphylococcus), some parasites (e.g., Plasmodium), some autoimmune disorders (e.g., drug-induced hemolytic anemia, atypical hemolytic uremic syndrome (aHUS)), …
How does hemolysis affect lab results?
Certain lab tests can be affected and the reported results will be inaccurate. It falsely decreases values such as RBC’s, HCT, and aPTT. It can also falsely elevate potassium, ammonia, magnesium, phosphorus, AST, ALT, LDH and PT.
What is hemolysis of a blood specimen How can you prevent hemolysis?
Best Practices to Prevent Hemolysis
- Use the correct needle size for blood collection (20-22 gauge).
- Avoid using butterfly needles, unless specifically requested by patient.
- Warm up the venipuncture site to increase blood flow.
- Allow disinfectant on venipuncture site to dry completely.
What are 3 causes of hemolysis?
Causes of hemolysis
- Hemolysis can be caused by:
- Shaking the tube too hard.
- Using a needle that is too small.
- Pulling back too hard on a syringe plunger.
- Pushing on a syringe plunger too hard when expelling blood into a collection device.
How is hemolysis treated?
Treatments for hemolytic anemia include blood transfusions, medicines, plasmapheresis (PLAZ-meh-feh-RE-sis), surgery, blood and marrow stem cell transplants, and lifestyle changes. People who have mild hemolytic anemia may not need treatment, as long as the condition doesn’t worsen.
What does it mean when your blood is Hemolyzed?
The term hemolysis designates the pathological process of breakdown of red blood cells in blood, which is typically accompanied by varying degrees of red tinge in serum or plasma once the whole blood specimen has been centrifuged.
What labs does hemolysis affect?
Potassium, aspartate transaminase (AST), amylase, calcium, phosphorus, magnesium, total protein, and total and direct bilirubin showed significant changes caused by hemolysis.
What happens during hemolysis?
Hemolytic anemia is a disorder in which red blood cells are destroyed faster than they can be made. The destruction of red blood cells is called hemolysis. Red blood cells carry oxygen to all parts of your body. If you have a lower than normal amount of red blood cells, you have anemia.
What is hemolysis and why does it occur?
Hemolysis is the destruction of red blood cells. Hemolysis can occur due to different causes and leads to the release of hemoglobin into the bloodstream. Normal red blood cells (erythrocytes) have a lifespan of about 120 days. After they die they break down and are removed from the circulation by the spleen.
What is a normal hemolysis level?
In general, a normal value for adults is 40 to 200 mg/dL. If your levels are lower, it means you may have hemolytic anemia, in which your red blood cells are prematurely destroyed. An undetectable level is almost always due to hemolytic anemia.
How is hemolysis diagnosed?
Diagnosis of Hemolytic Anemia
Hemolysis is suspected in patients with anemia and reticulocytosis. If hemolysis is suspected, a peripheral smear is examined and serum bilirubin, LDH, haptoglobin, and ALT are measured. The peripheral smear and reticulocyte count are the most important tests to diagnose hemolysis.
What kills red blood cells?
Red blood cells may be destroyed due to:
- An autoimmune problem in which the immune system mistakenly sees your own red blood cells as foreign substances and destroys them.
- Genetic defects within the red cells (such as sickle cell anemia, thalassemia, and G6PD deficiency)
