Circulating lymphoblasts
WebSep 1, 1980 · On initial admission, no correlation existed between the absolute number of circulating ALL blasts and the serum LDH levels ( Fig. 2). This phenomenon may be explained by the possibility that elevated serum LDH levels may relate more to total leukemic cell mass than to the numbers of circulating blasts. WebIf there is significant amount of circulating disease, ≥20% lymphoblasts or 1000 circulating lymphoblasts/mm3 in blood can establish the diagnosis. Immunophenotyping is essential, not only for diagnosis confirmation, but also to classify ALL into T cell (cCD3 or sCD3 positive) or B cell (CD19, CD22, CD79a positive), characterization of

A lymphoblast is a modified naive lymphocyte with altered cell morphology. It occurs when the lymphocyte is activated by an antigen (from antigen-presenting cells) and increased in volume by nucleus and cytoplasm growth as well as new mRNA and protein synthesis. The lymphoblast then starts dividing two to four times every 24 hours for three to five days, with a single lymphoblast making approximately 1000 clones of its original naive lymphocyte, with each clone sharing the …
