What causes ongoing low lymphs, low mchc and high rdw?

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. 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

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

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

Would polycythemia vera cause a low rdw?

Would polycythemia vera cause a low rdw?

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

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

What could cause low MCV and high RDW but normal MCH, hemoglobin, and hematocrit for over a year?

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

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
