Polychromasia can be observed in a lab test where specific red blood cells are blue-gray or bluish when stained by a particular type of dye. It happens when the red blood cells aren’t mature because they were released prematurely from the bone marrow. These cells that are not mature are known as Reticulocytes. Thus, polychromasia is an observation that helps identify the ailments or diseases that can cause problems inside these processes.

What is it meant to have mature blood cells?

In patients suffering from this, blood stem cells (immature cells) don’t mature into red blood cells, white blood cells, or platelets within the bone marrow. Blasts are immature blood cells that are not working correctly and may perish in the bone marrow shortly after reaching circulation.

What Causes Polychromasia?

The red blood cells in your body constitute the cells that make up your blood that supply oxygen to your body. They are created by your bone marrow, which expands for around seven days before being released into the bloodstream. Then, they transport oxygen to the other organs in your body. They also transport carbon dioxide back to the lungs so you can breathe it out while breathing.

The majority of the blood in your body is composed of white blood cells. They comprise 40%-45% of the total volume of blood. They usually live for approximately 120 days before they die off and must be replaced. Your kidneys create the hormone erythropoietin, which instructs your bone marrow to produce larger blood vessels.

Certain blood disorders can trigger your bone marrow’s cells to produce blood-forming cells before. Then these cells appear as polychromasia during an examination of blood called a smear of peripheral blood. Certain conditions that may cause are:

The condition can result from many different situations. When you have acquired hemolytic anemia, the body’s red blood cells but they’re destroyed too fast. Anemia that is developed can result from:

  • Tumors
  • An overactive spleen. It can be the part responsible for eliminating red blood cells
  • Infections caused by bacteria or viruses
  • Blood cancers
  • Lupus, rheumatoid arthritis, or any other auto-immune conditions
  • Mechanical heart valves
  • Acetaminophen is a type of medicine, which includes penicillin, and sulfa medicines

Pathological Features

The blood smears of patients suffering from HS have varying spherocytosis and the presence of polychromasia. Spherocytes can be described as round red blood cells smaller than normal RBCs, have no central pallor, and exhibit an increased (hyperchromic) staining. According to how severe the illness is, they are highly diverse in their number. In the mildest cases in HS, the spherocytes could be absent or rare.

After splenectomy, they are present, and post-splenectomy, RBC changes like target cells, Howell-Jolly body, and Pappenheimer bodies. A therapeutic splenectomy may be done in patients suffering from HS. The spleen’s histological examination generally reveals congestion of the splenic nerves because of spherocytes entrapped in contrast to the regular sinusoidal pattern seen in the case of passive congestion.

Myeloid metaplasia:

The condition occurs when your body creates red blood cells at locations different from the bone marrow. The bone marrow is infiltrated by substances that shouldn’t be present and function correctly. It may occur with cancers, such as lymphoma, multiple myeloma, and hairy cell leukemia.

Therapy with radiation:

The use of radiation therapy is a crucial treatment option for cancer patients. However, the majority of cancer treatments affect cancer cells and healthy cells. In some instances, radiation therapy may cause changes in how blood cells appear. This can cause polychromasia if your blood is tested again.

Tumors of bone marrow:

Tumors of bone marrow that the bone marrow suffers from abnormalities such as myelodysplastic metaphase.


Paris paroxysmal nocturnal hemoglobinuria. This condition causes blood clots and hemolytic.


Bleeding due to a trauma or bleeding disorder could cause an increase in the number of blood cells.

Radiation exposure:

Radiation exposure may cause polychromasia.

Symptoms of Polychromasia

It isn’t the cause of symptoms. However, the blood disorders that cause polychromatic can be accompanied by symptoms like:

  • Weakness
  • Fatigue
  • Easy bleeding
  • Paleness
  • Fever
  • Bone pain
  • Confusion
  • Larger spleen
  • Liver enlargement
  • Dizziness


What are the treatments of polychromasia?

The treatment for this condition is contingent on the reason. The cause could require specific treatment that is designed to eliminate these.

Blood transfusions:

Blood transfusions are required for conditions that cause severe anemia, such as sickle cell anemia and thalassemia.


Hypersplenism could require treatment with the surgical procedure splenectomy that removes the spleen.

Bone marrow transplants:

Bone marrow transplants could be required to treat conditions such as sickle cell anemia, thalassemia, and a few cancers. The treatment of antibodies such as Rituximab could be required to treat certain cancers.

What is the time you can see polychromatic?

These are reticulocytes. These are highly young reticulocytes because cells that show blue hues, “blue polychromasia,” are very young. It is most frequently seen when there is an intense erythropoietin response or extramedullary erythropoietin such as it is, for instance, the case with myelofibrosis and carcinomatosis.

Can anemia be the cause of Polychromatic?

Anemia may result from either excess or insufficient production of red blood cells and defective blood cells. Since more cells of red blood are required within the body at this time, they release early, leading to it.

Is polychromasia cancer?

A condition known as polycythemia (pol-e-sy-THEE-me-uh Veer-uh) is a blood cancer. It causes the bone marrow to create more red blood cells.

Is Polycythemia a death sentence?

There is currently no cure for PV. However, the condition is not necessarily fatal. As per the Leukemia & Lymphoma Society, the average lifespan after the diagnosis of 20 years.

Important key

Polychromatic may indicate a severe blood disease, like bleeding anemia and blood cancer.

Polychromatic and the blood disorders that cause it can be identified through a blood smear test. There are no signs of polychromatic as such. If you’re suffering from polychromasia, it’s crucial to see your doctor identify the root cause and discuss possible treatment options.
