High Rdw Causes
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 moreSee 1 more doctor answer
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
Iron supplements: Low MCV points to iron deficiency. High RDW points to the body making blood cells at a higher rate than normal.

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
Need more info: All laboratory results need to be interpreted in the clinical context and the doctor who ordered the tests is usually in the best position to do that. Having said that, it would have helped if you had provided the actual values. For good health - Have a diet rich in fresh vegetables, fruits, whole grains, low fat milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. 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. ...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 moreSee 1 more doctor answer
