Body fluid samples are obtained through collection of the fluid in a container or by inserting a needle into the body cavity and aspirating a portion of the fluid with a syringe. Ngan BY, Picker LJ, Medeiros LJ, Warnke RA. Chronic lymphocytic leukemia is an extremely heterogeneous disease and prognostic factors such as chromosomal abnormalities are important predictors of time to first treatment and survival. Immunophenotype is a key parameter that is very valuable in predicting response to treatment as well as survival rates. The abnormal cells grow, but they do not fight infections or perform other functions like normal WBCs.

Multivariate analysis identified CD34 and CD9 expression as independently predictive of the presence of at least one cytogenetic abnormality (P < 10(-4) and P < 0.03, respectively). No significant immunophenotypic abnormality was detected by flow cytometry. She always had a keen interest in medical and health science. Among B-lineage populations the following features were associated with malignant histology: 1) light-chain-restricted B lineage, 2) light chain -B lineage, 3) Leu-1+ B lineage, 4) L60+ B lineage, 5) 41H+, Ki-67+ B lineage, 6) loss of pan-B antigens, and 7) LFA-1-B lineage. Diagnostic hematopathology has become an increasingly complex subspecialty, particularly with neoplastic disorders of blood and bone marrow.
