FAQ
Q.Who is this test recommended for?
This test is recommended for individuals who are suspected of or have been diagnosed with B-cell–related hematologic disorders, including: • Chronic Lymphocytic Leukemia / Small Lymphocytic Lymphoma (CLL/SLL) • Follicular Lymphoma (FL) • Mantle Cell Lymphoma (MCL) • Marginal Zone Lymphoma (MZL) • Lymphoplasmacytic Lymphoma / Waldenström Macroglobulinemia (LPL/WM) • Monoclonal Gammopathy of Undetermined Significance (MGUS) • Multiple Myeloma • Individuals with unexplained lymphadenopathy or elevated lymphocyte counts It is also suitable for immune monitoring before, during, and after treatment.
Q.Can this test diagnose cancer?
This test primarily analyzes the B-cell immunophenotype. It can help: • Identify abnormal B-cell populations • Differentiate between B-cell hematologic malignancies • Assess disease activity • Provide diagnostic information for physicians However, a definitive diagnosis requires correlation with: • Complete Blood Count (CBC) • Peripheral Blood Smear • Bone Marrow Examination • Histopathology (Biopsy) • Genetic Testing • Clinical Presentation Final interpretation should be made by a hematology specialist.
Q.What does an abnormal test result mean?
Findings such as: • Monoclonal Kappa/Lambda light chain restriction • Abnormal expression of CD5, CD10, or CD23 • CD20 bright or dim expression • Abnormal CD38 expression may indicate abnormal B-cell proliferation or the presence of a hematologic malignancy. Test results should always be interpreted by a qualified physician together with other clinical and laboratory findings.
