What Red Cell Distribution Width low

Patient

Q: I have had blood work done at the same facility since 2012. The following are the results of the
Red Cell Distribution Width. My doctor only states "everything is within normal limits" however the results state it is low consistently. I am curious what would cause a low reading here, and why my doctor would always say things are normal?

A:   Hello,
Thank you for your query at AskTheDoctor.com

I understand your concern.
However, I want to reassure you that your hemoglobin values are fine and there is nothing to worry about. It has consistently been in the range of 13-14, and that is normal.
The limits are fixed according to statistical studies and minor variations like yours can be neglected.
As long as your hemoglobin is over 13, there is absolutely nothing to worry. In a country like India, for that matter, most women have a hemoglobin of around 10, and they do not show any symptoms.

So please do not worry.
Keep monitoring your values yearly once.

Hope this was helpful,
Regards.
