Question: What Does It Mean When Your RDW Is High?

How can you differentiate between iron deficiency anemia and thalassemia depending on CBC?

The two best measures or calculations from the CBC are the Red Blood Cell count alone (RBC) and the Mentzer Index (MCV/RBC).

An RBC above 5 x 1012/l is often seen in thalassemia, while a count <5 is more typical of iron deficiency..

Is high red blood cell count bad?

A high red blood cell count may be a symptom of a disease or disorder, although it doesn’t always indicate a health problem. Health or lifestyle factors can cause a high red blood cell count.

How long does it take for MCV to return to normal?

Stopping heavy drinking allows the bone marrow to recover, and the MCV usually returns to normal within two months.

What are the symptoms of high red blood cell count?

If you have a high RBC count, you could experience symptoms such as:fatigue.shortness of breath.joint pain.tenderness in the palms of the hands or soles of the feet.itching skin, particularly after a shower or bath.sleep disturbance.

What is the importance of the RDW?

The RDW test is commonly used to diagnose anemia, a condition in which your red blood cells can’t carry enough oxygen to the rest of your body. The RDW test may also be used to diagnose: Other blood disorders such as thalassemia, an inherited disease that can cause severe anemia.

What causes a low RDW?

a diet low in iron, vitamin B-12, or other nutrients. a family history of blood disorders, including thalassemia or sickle cell anemia. chronic illness, such as diabetes, HIV, or Crohn’s disease. dizziness, weakness, pale skin, or other symptoms of anemia.

What does low Rdw mean in blood work?

A low RDW (below 10.2%) means that the red blood cells vary very little in size. One reason for a low RDW level is macrocytic anemia. Another cause of a low RDW level is microcytic anemia.

What increases red blood cells?

Eating an iron-rich diet can increase your body’s production of RBCs. Iron-rich foods include: red meat, such as beef. organ meat, such as kidney and liver.

What does high RDW and normal MCV mean?

• A high RDW indicates a large variation in size of RBCs. If the MCV is normal and the RDW is high, there is a mixture of large and small RBCs. If the RDW is normal and the MCV is high, the RBCs are likely all macrocytic. If the MCV and RDW are both normal, the RBCs are likely all about the same normal size.

How high is too high RBC?

A high red blood cell count is generally considered to be anything above 6.1 million red blood cells for men, 5.4 million for women, and 5.5 for children.

How do you treat high red blood cell count?

How is a high red blood cell count treated? If a medical condition is causing a high red blood cell count, your doctor may recommend a procedure or medication to lower it. In a procedure called a phlebotomy, a health professional inserts a needle into your vein and drains blood through a tube into a bag or container.

Why RDW is normal in thalassemia?

2). In b and a thalassemia traits, almost all red cells are microcytic because deficient synthesis of the globin chain resulting from thalassemia mutations expresses itself in all of the red cell precursors. Consequently, RDW values are relatively constant.

What is the normal range for Rdw SD?

The width of the distribution curve is measured at the point that is 20% above the baseline. Since the RDW-SD is an actual measurement, it is not influenced by the MCV and more accurately reflects the red cell size variance. The normal RDW-SD range for adults is 40.0 – 55.0 fL.

What is a normal MCH level for a woman?

Normal MCH levels are around 27 to 33 picograms (pg) per cell in adults. These numbers may vary based on the machine used to carry out the test.

How do you reduce Rdw?

When MCV is low, RDW would increase more significantly. When iron therapy is given, RDW would elevate first and then gradually reduce at the normal level. To diagnose small cell and low pigment anaemia. To classify anaemia.

What is Microcytic anemia?

Microcytic anemia is defined as the presence of small, often hypochromic, red blood cells in a peripheral blood smear and is usually characterized by a low MCV (less than 83 micron 3). Iron deficiency is the most common cause of microcytic anemia.

How serious is Microcytic anemia?

As long as the underlying cause of the anemia can be treated, the anemia itself can be treated and even cured. In very severe cases, untreated microcytic anemia can become dangerous. It can cause tissue hypoxia. This is when the tissue is deprived of oxygen.

Why are RBC small in Microcytic anemia?

In microcytic anaemia, the red blood cells (erythrocytes) contain less hemoglobin and are usually also hypochromic, meaning that the red blood cells appear paler than usual.

Why is Rdw high in iron deficiency anemia?

However, a varied size distribution of red blood cells is a hallmark of iron deficiency anemia, and as such shows an increased RDW in virtually all cases. In the case of both iron and B12 deficiencies, there will normally be a mix of both large cells and small cells, causing the RDW to be elevated.

Is low Rdw bad?

A low RDW means your red blood cells are all about the same size. A high RDW means you have both very small and very large red blood cells. You may also have a “normal” RDW. A normal RDW range is 12.2%–16.1% for women and 11.8%–14.5% for men.

Why is iron deficiency anemia Microcytic?

Iron deficiency hypochromic microcytic anemia is caused due to disruption of iron supply in diet due to decreased iron content in the diet, pathology the small intestines like sprue and chronic diarrhea, gastrectomy, and deficiency of vitamin C in the diet.
