How could I have a low red blood count (rbc) but a normal hemoglobin and hematocrit?

How low?: An increase in red cell size, macrocytosis, may account for the disparity. Alcohol and low thyroid function may cause macrocytosis with near normal hemoglobin. ...Read more

I was wondering how I could have a low red blood count (rbc) but a normal hemoglobin and hematocrit?

No!: They all go together unless you have very small sized red cells in which case you can be anemic but the red blood cell count may still be normal... As in a conditiona called thalasemia. ...Read more

I have low rbc, hgb, hct, rdw-sd and high eos and mpv. Should I be concerned? I have neither iron deficiency nor other abnormal blood count.

It depends: It depends on what the exact finding of these values is. Sometimes these findings may be normal. Speak with your physician so he/she can properly interpret these results. ...Read more

I've had a number blood tests over the last year which show that I have a low RBC, but normal-high HGB - what could cause this?

I've had a number blood tests over the last year which show that I have a low RBC, but normal-high HGB - what could cause this?

Need actual values: If what you stated is correct, your red cell size may be larger, however, it would be helpful to have all the data, rather the qualitative statements alone. In any case if your hemoglobin is normal, there is no cause for concern. ...Read more

I am a 31 yo female. My WBC was 19 and my RBC was 3.1 (iron level 8.2). What does it mean to have a high white blood count and a low red blood count?

I am a 31 yo female. My WBC was 19 and my RBC was 3.1 (iron level 8.2). What does it mean to have a high white blood count and a low red blood count?

D/w your doctor: How is your period? Is it heavy? What is your ferritin? Hemoglobin? You should see your doctor and discuss with your doctor about your blood work result. You are anemic and your serum iron is low. You may have an iron deficiency anemia which is related to your heavy cycle perhaps vs other kind of anemia. Wbc can be elevated in different settings-like bleeding, infection, inflammation, cancer etc. ...Read more

What to do if my husband has low blood count. Hemoglobin 14, RBC 5.59, low WBC 3700, platelets 157000.?

What to do if my husband has low blood count. Hemoglobin 14, RBC 5.59, low WBC 3700, platelets 157000.?

Not too low: 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, the counts are not too low. Hemoglobin is normal. WBC is slightly low but may be his normal. platelets are at the lower end of normal. ...Read more

My husband has low blood count. Hemoglobin 14, RBC 5.59, low WBC 3700, platelets 157000. What's wrong with him?

My husband has low blood count. Hemoglobin 14, RBC 5.59, low WBC 3700, platelets 157000. What's wrong with him?

I think he's fine: There's no such thing as a perfect husband, but I don't see any problems with his blood picture. The total WBC count is actually at the low end of what I think is a reasonable reference range, and unless the neuts are very low or he's clearly sick clinically, I'd simply be thankful for good health. I trust he has other faults and that the two of you will be forbearing & love one another. ...Read more

My son is a 5 years old, he has ongoing periodical fevers, his blood work shows low HEMOGLOBIN, low HEMATOCRIT, low RBC, low LYMPHOCYTES, high BASOPHILS.

My son is a 5 years old, he has ongoing periodical fevers, his blood work shows low HEMOGLOBIN, low HEMATOCRIT, low RBC, low LYMPHOCYTES, high BASOPHILS.

Need to examine: It is not feasible to provide a meaningful opinion without examining your son and his health status warrants a thorough evaluation by a pediatrician and this is not an appropriate forum for such evaluation.
Wish you and you son good health! . ...Read more

Diagnosed (extreme low RBC / extra large white blood cells)vit d defi., white matter dis, sm vessel brain dis, BP aver.178/92.With no dia. Cause help?

High BP consquences?: You need to see a physician (p) about your anemia and WBC problems as well as controlling your hypertension. Your vit. D deficiency and anemia could be due to some chronic kidney disease, perhaps due to your high bp. Your small vessel and white matter diseases could be due, once again, to your high bp. See a p to get started on therapy and have some blood work sent off for a diagnosis and a cure. ...Read more

Is it bad to have low RBC and elevated bilirubin?

Is it bad to have low RBC and elevated bilirubin?

Low RBC: If the RBC has only recently come down below prior levels or below the lower limit of normal for the lab, when in combination with elevated biilrubin (especially the 'indirect form' of bilirubin) it can mean the RBC (red blood corpuscles) are being damaged and then they release their bilirubin into the bloodstream.
Have this checked soon ...Read more

How come my iron been very low for 5 years and I have NEVER had low RBC or Haemoglobin???

Iron storage: If you are having only one measure of your iron level checked, your iron storage form, or ferritin may be sufficient to avoid anemia. Next time you check you iron level, check ferritin and total iron-binding capacity as well as iron level to get the full picture ...Read more

I have slightly low RBC level, and slightly high homocysteine level. What is the cause and how can I correct it?

Diet and exercise: 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 to have the actual values, as slight is not a unit of measure.
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

Could my adrenals and thyroid levels being low affect my high iron but low RBC levels?

Could my adrenals and thyroid levels being low affect my high iron but low RBC levels?

High iron: Probably not. If you have been having low RBC levels you may have been given high doses of iron. If the low RBC is not iron deficiency anemia, then iron will not help. High iron in blood can cause many problems including accumulation in the liver causing hemachromatosis. ...Read more

Wondering about labs that show low wbc, low rbc, low neutrophils?

Patients not Labs: Doctors treat patients not labs, and with good reason. 90% of diagnoses are made via medical history and physical examination (something not currently practical via the internet). Labs are used to confirm or rule out specific concerns. What your labs means, depends on your specifics. The results may be important or insignificant; you need to check with your doctor. ...Read more

Low rbc, low hgb, high mcv, normal iron & B12 levels. What is the cause of anemia?

Low rbc, low hgb, high mcv, normal iron & B12 levels. What is the cause of anemia?

Macrocytic anemia: The most common causes of macrocytic anemia are B12 (ruled out for you) and folate (folic acid) deficiencies. Folate (folic acid) deficiency can be caused by diet (very rare - folate (folic acid) is everywhere), celiac disease, alcoholism, or hemolysis (autoimmune process, for example). Rarer causes include aplastic anemia and myelodysplastic syndrome (mds). If not clear to your doc, may need to see hematologist. ...Read more
