A reticulocyte count that is high, normal or low will aid with the classification process. A high reticulocyte count signifies that bone marrow processes are normal. A low reticulocyte count would signify there is a problem at the level of the bone marrow, which produce the stem cells. Acute blood loss would result in a high reticulocyte count ...
Leukocytes and platelets are normal. Bone marrow shows erythroid hyperplasia with a maturation arrest.In excess of 40% of the developing erythrocytes are ringed sideroblasts. Serum iron, percentage saturation and ferritin are increased. The total iron-binding capacity of the cells is normal to decreased. Stainable marrow hemosiderin is increased.
Waldenström's macroglobulinemia (also known as lymphoplasmacytic lymphoma) is a lymphoproliferative disease that involves an abnormal increase of lymphocytes within the bone marrow, creasing disruption of normal red blood cell production.

Myelodysplastic syndrome (MDS) is a form of blood cancer in which the bone marrow no longer produces enough healthy, normal blood cells. [9] MDS are a frequently unrecognized and rare group of bone marrow failure disorders, yet the incidence rate has rose from 143 reported cases in 1973 to approximately 15,000 cases in the United States each year.
The normal range for hemoglobin is 13.8 to 17.2 grams per deciliter (g/dL) for men and 12.1 to 15.1 g/dL for women. [6] Low hemoglobin indicates anemia but will be normal for LID. [5] Normal serum iron is between 60 and 170 micrograms per deciliter (μg/dL). [7] Normal total iron-binding capacity for both sexes is 240 to 450 μg/dL. [6]
Chromosome 5q deletion syndrome is an acquired, hematological disorder characterized by loss of part of the long arm (q arm, band 5q33.1) of human chromosome 5 in bone marrow myelocyte cells. This chromosome abnormality is most commonly associated with the myelodysplastic syndrome.
Polycythemia is defined as serum hematocrit (Hct) or hemoglobin (HgB) exceeding normal ranges expected for age and sex, typically Hct >49% in healthy adult men and >48% in women, or HgB >16.5 g/dL in men or >16.0 g/dL in women. [8] The definition is different for neonates and varies by age in children. [9] [10]
The condition arises from a fault in the bone marrow cells leading to over-production of platelets but the cause of the fault is unknown, and this type is not common. [2] When the cause is known such as another disorder or disease, the term thrombocytosis is preferred, as either secondary or reactive thrombocytosis. Reactive thrombocytosis is ...
