FLOW CYTOMETRY, CD 10 (CALLA)

The Flow Cytometry CD10 (CALLA) Test is a specialized immunophenotyping assay used to detect and measure the expression of CD10, also known as Common Acute Lymphoblastic Leukemia Antigen (CALLA), on the surface of blood, bone marrow, or lymphoid cells. CD10 is an important diagnostic marker used in the classification and evaluation of various hematological malignancies.

CD10 is normally expressed on early B-lymphocyte precursor cells, germinal center B cells, and certain other cell populations. Abnormal expression of CD10 may be associated with several leukemias, lymphomas, and lymphoproliferative disorders. Because of its diagnostic value, CD10 is routinely included in comprehensive flow cytometry panels used for leukemia and lymphoma immunophenotyping.

Flow cytometry technology enables rapid analysis of thousands of cells individually, allowing accurate identification of CD10-positive cell populations and their relationship to other cellular markers. The results help hematologists and pathologists classify diseases more precisely and guide treatment planning.

Benefits of the Test

• Detects CD10 (CALLA) expression on cells
• Assists in leukemia and lymphoma diagnosis
• Supports disease classification and immunophenotyping
• Helps identify abnormal lymphoid cell populations
• Aids treatment planning and monitoring
• Provides important diagnostic and prognostic information

Why Doctors Recommend This Test

Doctors may recommend Flow Cytometry CD10 testing for:

• Suspected Acute Lymphoblastic Leukemia (ALL)
• Suspected lymphoma
• B-cell lymphoproliferative disorders
• Abnormal blood counts
• Bone marrow abnormalities
• Evaluation of lymph node enlargement
• Monitoring hematological malignancies
• Comprehensive immunophenotyping studies

The test is usually performed as part of a multi-marker flow cytometry panel rather than as a standalone investigation.

Preparation Before Test

The test may require:

• Peripheral blood sample
• Bone marrow aspirate
• Lymph node specimen
• Body fluid specimen
• Other clinically appropriate samples

Preparation generally includes:

• No fasting is usually required
• Inform your doctor about ongoing treatments
• Follow laboratory instructions regarding specimen collection

The procedure involves routine specimen collection and advanced laboratory analysis.

Normal Reporting Time

Results are generally available within 1 to 3 working days, depending on panel complexity and laboratory workflow.

Who Should Take This Test?

• Patients with suspected leukemia
• Individuals with suspected lymphoma
• Patients with abnormal blood counts
• Individuals undergoing bone marrow evaluation
• Patients with lymphoproliferative disorders
• Individuals referred by hematologists or oncologists

The Flow Cytometry CD10 Test is an important tool in modern hematology and oncology diagnostics.

Clinical Significance

CD10 expression may be seen in:

• Acute Lymphoblastic Leukemia (ALL)
• B-cell precursor leukemias
• Follicular Lymphoma
• Burkitt Lymphoma
• Certain Diffuse Large B-cell Lymphomas
• Germinal center-derived B-cell neoplasms
• Other lymphoid malignancies

The presence or absence of CD10 helps clinicians differentiate between various leukemia and lymphoma subtypes and contributes to accurate disease classification.

Important Note

CD10 results must always be interpreted in conjunction with other flow cytometry markers such as CD19, CD20, CD34, CD45, TdT, CD5, CD23, and additional clinical and pathological findings. A comprehensive immunophenotypic profile is essential for accurate diagnosis.
