What does a low RDW mean on a blood test?

What does a low RDW mean on a  blood test?

Means nothing: A high RDW is a measure of the variability in size among red cells. When it is low, it's a fluke of statistics, and you should ignore it -- lab "normals" are set so that a few healthy folks lie outside. I run a high RDW as a frequent blood donor, and elevation is a common first-hint that something may be unusual; many healthies have high rdw's for various reasons. Labs mean nothing in isolation. ...Read more

I had a pre employment blood test and had high RDW and low mpv, is this something to worry about?

Thalassemia minor?: With normal packed cell volume, high red cell count, low MCV, I'd consider you may have thalassemia minor. This is good to know because if you marry someone else who has this, the children may have the very serious thalassemia major. Talk with your physician about this and what he/she thinks is actually going on. ...Read more

Everybody...: ...Is "susceptible" to HIV - as in, able to catch it if exposed. If the question is "do I have hiv, " only an HIV test can answer that with any degree of reliability, and the tests you mention do not help with that question one way or another. ...Read more

Further evaluation: There are many common causes of fatigue that have not yet been ruled out. You likely did not get adequate thyroid tests. You might have chronic infections such as lyme disease or viral infections, intestinal parasites, heavy metal toxicity, mold toxicity, corticoadrenal insufficiency, depression, vitamin or mineral deficiencies, sleep apnea, food sensitivities etc. Please see my comment:. ...Read more

Anemia found on blood test. Low hemoglobin, hematocrit, mcv, mch, high rdw. Have had heavy periods for a few years but why would it just show up now?

Anemia found on blood test. Low hemoglobin, hematocrit, mcv, mch, high rdw. Have had heavy periods for a few years but why would it just show up now?

It takes time to exh: We all carry extra reserves of blood and iron stores in our body which can make up for moderate blood losses for a long time. Only when the reserve is exhausted and there is no more iron left in the body will your blood tests start showing up Anemia. You need to ask your doctor for providing you the raw materials(like Iron supplements) to help you make extra blood. ...Read more
