Often, they’ll look at the results of an RDW (variation in red blood cell size) alongside the results of the MCV (average red blood cell size) to assess the health of your red blood cells. Low RDW A low RDW isn’t usually a cause for concern and isn’t associated with any particular types of anemia.
The typical low RDW symptoms include shortness of breath, diarrhea, weak muscles, glossitis (swelling of the tongue), severe paleness of the skin, nausea, rapid heart rate, loss of appetite, which could lead to weight loss. What is the significant clinical applications of RDW in a blood test?
Normal Range. RDW normally ranges from 11.5 – 15%. The range may slightly vary between laboratories. However, a normal RDW doesn’t mean a condition such as anemia is absent. Your doctor will interpret your results in conjunction with your medical history and other test results. Low RDW.
A low RDW level is typically not a cause for concern, but a high RDW level can indicate certain types of anemia or occur in other chronic conditions. Experts combine results from an RDW blood test with other red blood indices to make a diagnosis.
A red cell distribution width (RDW) blood test helps measure variation in red blood cell volume and size. Learn why it’s performed and how to read results.
RDW test results may be higher if the cells have a wide range of sizes. A high or low RDW may suggest an individual has an underlying health condition.
What is it used for? The RDW blood test is often part of a complete blood count (CBC), a group of tests that measures the number and type of cells in your blood, including red cells. The RDW test is commonly used to help diagnose or determine what's causing anemia, a condition in which your body does not make enough red blood cells.
Red cell distribution width (RDW) test identifies the sum of red blood cell variation in volume and size. Get the meaning behind a low or high test result and more.
FAQ. The red cell distribution width (RDW) blood test measures how equal your red blood cells are in size. One of several tests included in a complete blood count (CBC), RDW is measured as a percentage. The normal range for RDW in adults is 12% to 15%. However, the reference range can vary based on the lab.
The Red Cell Distribution Width (RDW) Blood Test is a diagnostic tool used to measure the variation in size of red blood cells in a blood sample. A higher RDW value indicates a greater variation in size, which can be indicative of various health conditions.
