1 Anisocytosis: when the red blood cells show different sizes or diameters in the same extension, the presence of anisocytosis is referred to, which can be moderate or severe. Its finding is very frequent, non-specific and constant in transfused patients.

What can cause anisocytosis?
Anisocytosis is called an anomaly in the size of red blood cells by which they have a uniform size, instead of varying between them. This fact is usually caused, in its great majority, by some form of anemia and is detected through a blood test.
How serious is anisocytosis?
Anisocytosis and anemia
If there are not enough red blood cells to move the hemoglobin, the heart has to work much harder. This can cause murmurs, arrhythmias (problems with the heart rate or rhythm of the heartbeat), enlargement of the heart, including heart failure.
How is anisocytosis cured?
If it is anisocytosis caused by uncomplicated anemia, it can be treated with iron supplements. If it is determined that it is due to a lack of vitamins, the necessary contribution of these nutrients will be given and if it was due to another type of anemia, then the treatment will be more complex and lifelong.
How to lower RDW levels?
There is no specific treatment that reduces the amplitude of erythrocyte distribution, since it is a secondary parameter in blood tests. To lower high RDW levels, the disease that is causing them must be treated.

What is the cause of Acanthocytosis?
Acanthocytes are generated when normal red cells are exposed to conditions that modify the lipid content of their membrane, altering the free cholesterol/phospholipid ratio in certain areas of the membrane.
What does acanthocytosis mean?
Chorea-acanthocytosis (ChA) is an autosomal recessive disease that is caused by the appearance of a mutation located on chromosome 9q21 in the VPS13A gene that encodes a protein called chorein.
What are acanthocytes in urine?
Acanthocytes are abnormal ring-shaped erythrocytes with a glued membrane that should be investigated by trained professionals (Cohen). The presence of blood casts indicates that the bleeding is glomerular, this finding is very specific but not very sensitive.
What are acanthocytes in dogs?
Acanthocytes, which are cells that look similar to echinocytes but have a morphology more similar to a normal erythrocyte. Likewise, they present membrane projections, but in this case they are irregularly distributed and are of different sizes (figure 4).
How to know if your dog has anemia?
Symptoms of anemia in dogs
In this way, the most common symptoms are: lack of appetite, weakness, depression, little desire to move, play or exercise, pink or whitish gums and tongue, tachycardia, fainting, difficulty breathing, yellow eyes , among others.
What happens when the hematocrit is high in dogs?
High red blood cells.
This is usually due to dehydration (actually there are not more cells, but less plasma), but it is also seen in some lung diseases, in bone marrow tumors or in high altitude areas where there is little oxygen in the air.
How to know what type of anemia a dog has?
A simple blood test can diagnose anemia. Most veterinarians can perform a rapid blood test called a hematocrit (PCV) in the hospital. The PCV Indicates the volume of red blood cells in the bloodstream.
What is glomerular disease?
Glomerulonephritis is also called glomerular disease or glomerulopathy. It is a type of kidney disorder caused by damage to the glomeruli as a result of hyperactivation of the immune system.
Why do I have microscopic hematuria?
Microscopic urinary bleeding is a common symptom of glomerulonephritis, an inflammation of the kidneys’ filtering system. Glomerulonephritis can be part of a general disease, such as diabetes, or it can occur on its own.
What is the normal value of red blood cells in urine?
A normal result is 4 red blood cells per high power field (HRG/HFF) or less when the sample is examined under a microscope. The example above is a common measurement for a test result. Normal value ranges may vary slightly between different laboratories.
What causes hemolytic anemia?
Hemolytic anemia occurs when the bone marrow is not making enough red blood cells to replace those that are being destroyed.
What is a Heinz body?
Hemoglobin precipitates that can be seen microscopically inside red blood cells.
What does it mean to have a high RDW?
Elevated RDW values are interpreted along with hemoglobin and MCV (Mean Corpuscular Volume) to distinguish between different types of anemia. If VCM is elevated and RDW is also elevated, it may be due to: Megaloblastic anemia. Autoimmune hemolytic anemia.
What is RDW and its normal values?
By definition, the RDW describes the percentage variation (statistically being a coefficient of variation) of the size of the GR, where its formula is: [desviación estándar/volumen corpuscular medio] × 100. It depends on each clinical laboratory, but generally, its normal value ranges from 11% to 15.0%4.
What if I have high PDW?
Analyzing both indices together (PDW–VPM) is useful in the study of thrombocytopenia. If both indices are elevated, it suggests peripheral platelet destruction, as is the case with hypersplenism and immune thrombocytopenic purpura.
