What does it mean when Burr cells are present?
The presence of cells called burr cells may indicate: Abnormally high level of nitrogen waste products in the blood (uremia)
Are Burr cells normal?
Burr cells, also known as echinocytes, have a speculated border over the entire cell surface. Burr cells are commonly found in both end-stage renal disease and liver disease. In our study, Burr cells were found in 80% of healthy individuals although the numbers of cells are very small.
What causes Burr cells?
Crenated erythrocytes are most commonly caused by excess EDTA (underfilled collection tube), but may also be caused by slow drying, drying in a humid environment, or an alkaline pH from glass slides. When crenation is an artifact, most cells on the slide will exhibit this characteristic.
What are Burr red blood cells?
Echinocytes (also called burr cells) have serrated edges over the entire surface of the cell and often appear crenated in a blood smear (picture 3). Although often confused with acanthocytes, the projections of the red cell membrane are smaller and much more uniform in shape and distribution in echinocytes.
What causes Spherocytes blood?
Spherocytosis is one of the most common inherited hemolytic anemias. It is caused by a defect in the erythrocyte membrane, which leads to an increased permeability for sodium and water, giving the erythrocyte its typical spherical form.
Can anemia cause Burr cells?
Burr cells have been described in association with a variety of disorders, including the following: hemolytic anemia of various causes, kidney disease, liver disease, vitamin E deficiency, increased intracellular calcium, alkalosis, and drug-induced (mesna, 5-fluorouracil, and benzodiazepines).
What are target cells indicative of?
Presence of cells called target cells may be due to: Deficiency of an enzyme called lecithin cholesterol acyl transferase. Abnormal hemoglobin, the protein in RBCs that carries oxygen (hemoglobinopathies) Iron deficiency. Liver disease.
Is it normal to have Spherocytes?
It is estimated that 20 to 30 percent of people with hereditary spherocytosis have the mild form, 60 to 70 percent have the moderate form, 10 percent have the moderate/severe form, and 3 to 5 percent have the severe form. People with the mild form may have very mild anemia or sometimes have no symptoms.
Can I donate blood if I have spherocytosis?
1. Must not donate if: Clinically significant haemolysis.
What disease has target cells?
There are four major circumstances in which target cells appear as the major morphologic abnormality: thalassemia, hepatic disease with jaundice, hemoglobin C disorders, and the postsplenectomy state. Lesser numbers of target cells are found in sickle cell anemia, iron deficiency, and lead intoxication.
Why do I have burr cells in my blood?
Some long-distance runners may have echinocytosis, the presence of echinocytes in their blood, as well. It isn't clear how or why burr cells form in these situations. One possible mechanism in some of these cases is that the red blood cells are depleted of an energy currency known as ATP.
Are there any reversible symptoms of burr cells?
In many cases, the symptoms are reversible with proper treatment. Crenated cells, or red blood cells that mimic the appearance of burr cells, are frequent artifacts within blood smear tests.
What kind of cell is a burr cell?
A burr cell might be a bit smaller than a normal red blood cell and might have what's known as central pallor, or a centrally pale region. The morphological changes associated with burr cells may be reversible under some circumstances. Burr cells are also called: Echinocytes, which means sea urchin cells and is a commonly used synonym.
What causes a burr cell on a slide?
Crenated erythrocytes are most commonly caused by excess EDTA (underfilled collection tube), but may also be caused by slow drying, drying in a humid environment, or an alkaline pH from glass slides. When crenation is an artifact, most cells on the slide will exhibit this characteristic. True burr cells are less numerous.
