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

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

What causes my MCV to be low and RDW to be high? And how to prevent it?

What causes my  MCV to be low and RDW to be high? And how to prevent it?

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

Been supplementing with B12: its now at 1430 but MCH is still high and RDW is still low! Other causes for this??

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

What could cause high mch, high mcv, low rdw, low B12 and high iga??

What could cause high mch, high mcv, low rdw, low B12 and high iga??

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

What is a cause for a low WBC and a high RDW?

What is a cause for a low WBC and a high RDW?

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

9yrs old with severe back pain.  Ruled out scoliosis. Low RBC and high rdw. No injury we know off. What could cause it and how to help her?

Need to make Diagnos: All we can suggest is at the age of 9years with severe back pain without history of trauma, before you plan treatment apart from pain meds which she is already getting.You need to find the cause of pain.You should consult a pediatric orthopedic specialist as she needs a thorough history and physical exam and may need imaging like mri/cat scan and may need other tests if indicated. ...Read more

Help with test results high RBC 5.19, hgb 15.5, hct 45.4, low RDW 11.6, &ldh 117? What does this mean? Does my obgyn need this info, cause miscarriage?

Help with test results high RBC 5.19, hgb 15.5, hct 45.4, low RDW 11.6, &ldh 117? What does this mean? Does my obgyn need this info, cause miscarriage?

No major issue, but.: Should tell your ob, since the h&h are a little high for female, so could indicate mild dehydration--which can cause ptl / irritation. Rdw is measure of the diameters of red blood cells (rbc) to see if too high a #, suggests problem. Little low no biggie. Lactate dehydrogenase (ldh - aka: "little darn help") is a very nonspecific marker of inflammation / body activity, but is ok. ...Read more

Does anemia cause irreg hr? My machine gives the irreg hr signal but heart workup was normal. Hemo in canada val is 116 and iron is 8. Tibc high RDW HGH MCV low. Im worried. More tests being done.

No: Anemia does not cause irregular rhythm. Your heart w/u can be normal and you can still have extra beats which are present to some degree in all normal people. You have iron deficiency anemia which is due to blood loss and, in your age group. Most likely a result of menstruation. Take iron supplements. ...Read more

Low hemoglobin (11.6),low mch, high rdw, low alkaline phosphates, all other values normal including rbc and b12. Possible cause? Iron deficiency?

Low hemoglobin (11.6),low mch, high rdw, low alkaline phosphates, all other values normal including rbc and b12. Possible cause? Iron deficiency?

May be: 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, iron deficiency is not uncommon in women in their reproductive years. It would be safe to take oral iron and multivitamin supplements and recheck hemoglobin at your next visit to your doctor. 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

Is a B12 level of 294 low enough to cause symptoms? Iron studies are being done now. Rdw is high, hemo low and MCH low. 10 brain lesions on MRI and hert palps and dizziness.

Is a B12 level of 294 low enough to cause symptoms? Iron studies are being done now. Rdw is high, hemo low and MCH low. 10 brain lesions on MRI and hert palps and dizziness.

Symptoms B12: Level of 294 is borderline low. I would do a confirmation study (mma). If it is elevated -and if your iron is okay- then likely vit B12 deficiency contributes to your anemia. Yes, it can cause some symptoms-like fatigue, numbness, tingling, forgetful etc- but not heart palpitation- unless if your hemoglobin is less than 8-then yes, you could have palpitation and dizziness from it. F/u md. ...Read more

Rdw going up 15.2 mvp 7.6 mchc low also? Could this be due to fatty liver? Could this cause easy bruising WBC was normal

Rdw going up 15.2 mvp 7.6 mchc low also? Could this be due to fatty liver? Could this cause easy bruising  WBC was normal

None of these...: Have anything to do with the liver; they tell us nothing about the state of the liver, good or bad. Also, if the rest of the CBC is normal, the only things these indices suggest is a very mild iron deficiency. ...Read more

Is RDW of 10.8 low?

Low but...: If you are asking about RDW that is part of a CBC report in United States, a value lower than 80 is usually considered low (different labs may have different norms ). A low RDW may be suggestive of iron deficiency, thalassemia (or other altered red cells), or other blood problems. However, a value of 10.9 is too low unless a different measurement. ...Read more

What will happen if my RDW (9.18%) is low?

What will happen if my RDW (9.18%) is low?

Probably nothing: The RDW is how the size of your red blood cells varies with the mean size of your red blood cells. There is no harm in having a low rdw. Certain types of anemia can lead to low rdw, and that may be a problem that needs to be treated. ...Read more
