What does having low MCV high red blood cells with abnormal morphology with low neutrophils and high lymphocytes counts mean?
Thalassemia? Low MCV (small sized) red cells with increased number of rbcs is most commonly seen with thalassemia, an inherited hemoglobin abnormality, but it is not associated with low neutrophils. Not all low neutrophil counts are significant, as normal varies with ethnic background. Infections can cause temporary low neutrophils. See a hematologist to sort this out.
Low MCV high red blood cells with abnormal morphology with low neutrophils and high lymphocytes counts?
Means nothing alone. In isolation from the patient story, lab tests mean nothing. This is especially true since we have no actual numbers. The low MCV and high rbc would make any physician think of a thalassemia, but it would be criminal to speculate further without knowing more about the person. If this is a you or a family member, you have a right and a duty to request your doctor's thoughts, or get consultation.
19 months has red blood cells count 5.60 (4-5.2). Mcv 68 (70-85), rdw, RBC 19.8 (12-16.5) neutrophils 18 (24-62) lymphocytes 75 (31-65) abnormal RBC morph?
Likely iron def. There are several abnormalities, your red count is relatively normal but the cells are borderline small, with a large variation in the sizes of red cells, indicating a possible mixed picture. You have a large number of lymphocytes with relatively low granulocytic white cells, which sometimes indicates a viral infection. Iron studies might be useful, and a lost art would be to look at the slide.
