Elevated Rdw Causes
Different thing: You could have more than one conditons like low in iron and low in vitamin B12 for instance- that would make normal MCV and high rdw. Or you could be just in the very beginning or mild case of low iron- that would present the same in cbc. Go to see your md and get checked. ...Read more
Low hgb, rbc, low norm hct, WBC 7.5, basos & esons elevated. Ig%. 7 mcv, RDW norm. Iron 89 to 49 tibc 422 to 345 ferr 180 to 96, sat% 20-11.6. Cause?
Non-specific: Variation in red cell size can be due to many reasons, e.g., iron deficiency, hemolytic anemia, folate (folic acid) and/or B12 deficiency. All lab results need to be interpreted in the clinical context and the doctor who ordered the test is usually in the best position to do that. ...Read more
What does an elevated RDW level mean if all other levels are within normal range? RDW level is 15.1%
Random Dist Width: Random distribution width (RDW) is a measure of the variability of the sizes (volume) of the red blood cells in a complete blood count. The lower the number, the more similar are the sizes of the red cells. The higher the rdw, the more variable are the red cells in sizes (from small to large). The variability in red cell sizes can sometimes help narrow down the causes of anemia in a patient. ...Read more
Hematology: If the red cell, total white blood cell and platelet counts, as well as the MCV and MCH are all normal, the low MCHC and high RDW may not be significant or diagnostic. Low lymphocytes combined with high neutrophils can be seen in certain infections, use of corticosteroids, or in blood dyscrasias. However this question can be better answered by your MD (who knows your results) or a hematologist ...Read more
Don't Rx a lab: Early iron deficiency often does this, but remember that lab reference ranges are set so that a few percent of healthies fall outside on either end. Especially, don't get all worried about trying to adjust a lab value back into reference range; something is always outside. ...Read more
My son (13) has a slightly elevated RDW (14.8%) and a slightly low mchc reading (32.5%). What does this mean?
What do you suggest if my son (13) has a slightly elevated RDW (14.8%) and a slightly low mchc reading (32.5%) - meaning?
Hard to say: Without the context of other lab values, these isolated numbers from a CBC cannot be interpreted. Also, isolated lab values mean nothing by themselves - they are just one tiny clue in a picture of your total health. Don't treat numbers, treat people. Everything has to be taken in context, and commenting on these numbers out of context would be a disservice to you and your son. ...Read more
Need more info:
Why were these tests done? Do you have any symptoms? RDW of 56 does not appear to be a valid result. You should discuss this with the doctor who ordered the tests.
For good health - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Drink enough water daily, so that your urine is mostly colorless. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form.
Practice safe sex, if you have sex. ...Read more
Iron supplements: Low MCV points to iron deficiency. High RDW points to the body making blood cells at a higher rate than normal. An iron supplement might be a good idea, be it from a pill, diet or both. However, you need to check with the doc who ordered these tests to make sure there isn't something else going on. ...Read more
Anemia: Low mch, mcv levels could mean low iron and blood loss from stomach or intestines, from cancer or ulcer, if take too many aspirins or drink too much alcohol can do this, may be not srious, high rdw means different sizes of red cells, best to be evaluated by a hematologist to be sure what it is. ...Read more
Been supplementing with B12: its now at 1430 but MCH is still high and RDW is still low! Other causes for this??
Okay: Low RDW means nothing. Reference ranges arbitrarily exclude several percent of healthies on either end. MCH isn't a value worth following. Having a check for folic acid may be worthwhile, and you may have a cold agglutinin that causes two or more red cells to be counted as one (that would tend to raise RDW though). Thyroid okay? You're not a drinker I trust. Reticulocyte count normal? ...Read more
Why would my bili be elevated on off for a yr? The biggest part is indirect however last few times direct has been slightly it was 0.24. My RDW is up.
Give us the numbers: Unless you give us the actual bilirubin values, we can not be very helpful. Total bilirubin level is all that matters...so do not worry about fraction like direct or indirect unless the bili level is >1.5 mg. Many people have slight elevation of bilirubin, which is harmless as long as the liver enzymes (SGOT/SGPT and Alkaline Phosphatase are not elevated. ...Read more
Tapeworm: The High MCV and MCH would be expected with B12 deficiency as the RBC's are being discharge young from the bone marrow. Low RDW just tells you you have only one predominant population of RBCs (dark large ones) Elevated IgA can be caused by several conditions but a tapewor taking up residence in the terminal ilium would block the binding of intrinsic factor / B12 complex to its receptors. ...Read more
Not that I know of.: The big changes of this are elevated rbc count, hemoglobin, hematocrit, and decreased ESR (erythrocyte sedimentation rate). The elevations come without decrease in volume, and can be up to 70-80% for hematocrit, and 8-9 million rbc count. Changes in RDW may be from so many rbc's in the system, but even if they do occur, do not apparently have effect on prognosis or relevance to the cause of this. ...Read more

Meaningless: Rdw has no meaning unless you are anemic and your MCV is low. Mch also has no meaning. ...Read more
Suggests low iron: Mean corpuscular hemoglobin (mch) relates to how much hemoglobin on your red blood cell (see mchc - adds concentration to mch). Forget exact acronym, but RDW measures (via flow cytometry) size of many red cells--normal to have all about one size. If becoming anemic, see wide variation which raises RDW #. Both of these can be due to low iron, but also folate (folic acid) or B12--ask your Dr for context & plan ...Read more

What does it mean if my MPV is always elevated and WBC are always low? RDW is occasionally elevated but not often.
MPV=mean platelet value. Largely meaningless in most patients.
WBC=white blood cell count composed of several different cell types that respond differently, thus rising or falling variably according to the stimulus
RDW=red cell distribution width, a measure of how variable red cell sizes are, again not specific but sometimes useful if you are anemic. ...Read more
Hi. I recently found out I'm pregnant and had my labs drawn. My MCH and mchc were slightly elevated and my RDW was slighlty low. What could this mean?
Sphereocytoses: Sphereocytoses is an rbc product that has a greatter volume than normal rbcs, consequently its size is smaller but the MCH and MCHC elevations are consistent with a spherocyte which is more like a ball than a checker which explains the difference in volume. ...Read more
Is a sed rate of 30 high? What does this mean? A cause of my chronic hives? Also my rdw was high...at a 18.8
Sed rate: A sed rate of 30 is not too high, normal is up to around 20. It is a lab doctors use to follow inflammation in the body, it may be high due to your hives, or arthritis, or infection, or another auto immune disease. You do not treat a see rate, rather you look for some cause of inflammation in the body that may be triggering it to be elevated. ...Read more
What could cause low MCV and high RDW but normal MCH, hemoglobin, and hematocrit for over a year?
How low?: Reference ranges are set so that several percent of healthy folks fall outside on either end. If your peripheral smear is unremarkable and the MCV above 70, I'd forget the whole thing. My RDW is always high from donating blood. There are some variants of thalassemia minor that will produce this and puzzle people over a lifetime, though MCH is usually lowish. ...Read more
What does elevated RBC 5.51, RDW 14.9, neutros 8.0 neutrophilia with low MCH 25.6, mchc 318, low ferritin 6 after 3 months of iron pills was 4 mean?
Iron def: If your ferritin is still 6 after taking the iron pills for 3 months- that means you do not have a good response from the iron pills. That could be due not absorbing well or you continue to bleed heavily etc. First, make sure you take iron 3x/day-take it in empty stomach with orange juice or vit c. If still low- consider IV iron. Also check with gyne if you have heavy periods and f/u with pcp. ...Read more
Mcv 69, MCH 22.6, mchc 32.7 (low), high RDW 16.1. Hg/hct normal. Rbc 6.45 (high). Numbers have declined over past 7 months. Iron norm. What is cause?
Need evaluation: All lab results need to be evaluated in the clinical context and the doctor who ordered the test is usually in the best position to do that. It would also help to have the actual results of iron studies. Iron deficiency is a common cause of microcytic hypochromia. Mild thalassemia being another one. If your results are improving, recovery from iron deficiency is a likely explanation. ...Read more
