Description
Blood, NA, Fasting or Non Fasting: As suggested by doctor.
Sample Required:
A small sample of blood is required for the RDW (Red Cell Distribution Width) test. It is typically collected through a simple blood draw from a vein in the arm.
Test Time:
The test results are usually available within a day or two after the blood sample is taken, depending on the laboratory and healthcare facility.
Test Normal Range:
The normal range for RDW is typically between 11.5% and 14.5%. However, the reference range may vary slightly depending on the laboratory and the specific testing method used.
What is the test?
The RDW blood test measures the variation in the size of red blood cells (RBCs) in a blood sample. It provides information about the degree of variability in the size of RBCs, which can help in the diagnosis and monitoring of certain medical conditions.
Test Procedure:
To perform the RDW blood test, a healthcare professional will clean the area on your arm and insert a needle into a vein. A small amount of blood will be drawn and collected in a test tube or vial. The sample is then sent to a laboratory for analysis.
When to take the test?
The RDW blood test may be ordered as part of a routine complete blood count (CBC) or if a healthcare provider suspects an underlying condition affecting the size of red blood cells. The test may be used to evaluate conditions such as anemia, nutritional deficiencies, or certain chronic diseases.
Who should take this test?
Individuals with symptoms of anemia, such as fatigue, weakness, pale skin, or shortness of breath, may be recommended to take the RDW blood test. Additionally, those with known blood disorders or chronic diseases affecting red blood cells may undergo this test to monitor their condition.
Precautions for exceptional cases (pregnancy etc.):
There are generally no specific precautions for the RDW blood test. However, it is always important to inform your healthcare provider if you are pregnant or have any other medical conditions or concerns that may impact the interpretation of the test results.
