Test Overview & Methodology
The CD33 immunophenotyping by flow cytometry test quantitatively assesses the expression of CD33 antigen on hematopoietic cells, primarily aiding in the diagnosis and monitoring of acute myeloid leukemia (AML). This assay utilizes multilaser flow cytometry with CD33-specific monoclonal antibodies to accurately identify myeloid lineage blasts and quantify antigen density, supporting both initial diagnostic workup and minimal residual disease (MRD) surveillance.

Sample Collection & Logistics
Sample Requirements: One 3 mL Lavender Top (EDTA) tube AND one 3 mL Green Top (Sodium Heparin) tube of whole blood, OR 2 mL bone marrow in Green Top (Sodium Heparin). Ship immediately at 18โ22ยฐC. DO NOT REFRIGERATE OR FREEZE. Record time, date, and clinical details on request form.
Hospital Extraction Only โ All sample collections are performed within an accredited hospital facility. Mobile home phlebotomy is not available for this test.
Physician Insight & Safety Protocols
"CD33 flow cytometry is a cornerstone in the diagnostic workflow for acute myeloid leukemia, providing critical immunophenotypic data that must be integrated with bone marrow morphology, cytogenetics, and molecular genetics. A positive CD33 result strongly suggests myeloid lineage involvement but is never a standalone verdict. Serial monitoring by flow cytometry enables sensitive detection of minimal residual disease, guiding risk-adapted therapeutic decisions. Always correlate with the full clinical picture before altering any treatment regimen."

Key Safety Advisory
Do not discontinue prescribed chemotherapy, targeted therapy, or supportive medications without explicit consultation with your treating hematologist.
Exclusion Criteria & Emergency Red Flags
- Patients with severe thrombocytopenia (platelet count <10,000/ยตL) requiring immediate transfusion
- Uncontrolled active bleeding or hemodynamic instability
- Known allergy to heparin (for green top tube collection)
- Fever >38.5ยฐC with suspected sepsis; prioritize urgent medical care
- Severe bone pain or acute neurological symptoms โ go to ER immediately before test
Patient FAQ & Clinical Guidance
1. What does a CD33 positive result indicate?
A CD33 positive result typically indicates the presence of myeloid lineage cells; in the appropriate clinical setting, it strongly supports a diagnosis of acute myeloid leukemia (AML) and guides targeted therapy decisions such as gemtuzumab ozogamicin.
2. Is fasting required before the test?
Fasting is not required for CD33 flow cytometry. However, inform your physician of all medications and supplements, as certain therapies may affect antigen expression and result interpretation.
3. Can this test monitor minimal residual disease (MRD)?
Yes, CD33 flow cytometry is an essential tool for MRD monitoring in AML, enabling early detection of relapse and assessment of treatment efficacy with high sensitivity down to 0.01% blasts.
