Test Overview & Methodology
CD22 Immunophenotyping by Flow Cytometry precisely quantifies the CD22 antigen expression on B‑lymphoid cells. It is a pivotal diagnostic and monitoring tool for B‑cell leukemias and lymphomas. This test employs multiparametric fluorescent flow cytometry to deliver same‑day, DHA‑compliant results, accelerating targeted therapy decisions in the UAE.
Comparative Diagnostic Precision
| Feature | Our ISO-Accredited CD22 Test | Basic Immunophenotyping Panel |
|---|---|---|
| Diagnostic Precision | Quantitative CD22 expression (99.9% sensitivity) | Qualitative surface markers only |
| Methodology | Fluorescent Flow Cytometry (LC‑MS/MS verification) | Standard flow cytometry, limited fluorophores |
| Turnaround Time | Same day (sample by 9 AM) | 24–72 hours |
Physician Insight & Safety Protocols
Mr. Prabhakar Reddy Kalathoor, Specialist Diagnostic Radiology (DHA License: 61713011), emphasizes: “CD22 expression analysis is a critical tool in the diagnostic workup and therapeutic monitoring of B‑cell malignancies. However, results must always be interpreted within the full clinical context, including morphology and cytogenetics. This test serves as a guiding beacon, not a standalone verdict, and I strongly advise patients to discuss the implications with their treating hematologist‑oncologist.”
Advisory Medication Warning
Do not discontinue prescribed medication without consulting your doctor. Certain therapies (e.g., monoclonal antibodies like Rituximab, immunosuppressants, or targeted inhibitors) can significantly influence CD22 surface expression. It is imperative to inform both the phlebotomist and the requesting physician of your complete current medication list and clinical history.
Exclusion Criteria & Emergency Red Flags
- Home Collection Exclusion: Patients with active fever (>38.5°C), hemodynamic instability, or severe thrombocytopenia (<20,000/μL) unless medically cleared.
- Bone Marrow Sampling Contraindications: Strictly performed at the hospital. Contraindications include uncorrected bleeding diathesis or localized infection over the aspiration site.
- Consent for Minors: Mandatory parental/guardian consent is required in adherence to UAE Federal Law No. 2 of 2019.
- Red Flags – Seek Immediate Emergency Care: Sudden high fever with rigors, uncontrolled bleeding, or rapid enlargement of lymph nodes within 24 hours of sample collection.
Patient FAQ & Clinical Guidance
1. What is the clinical utility of the CD22 Immunophenotyping test?
This test quantitatively measures CD22 antigen expression on B-cells. It is primarily used for diagnosing and sub-classifying B-cell leukemias and lymphomas, monitoring minimal residual disease (MRD), and determining eligibility for targeted therapies such as inotuzumab ozogamicin.
2. How is the CD22 Immunophenotyping test performed and what is the turnaround time?
The test requires a peripheral blood draw or a bone marrow aspirate (if clinically indicated). The sample is processed using multiparametric flow cytometry. Results are available the same day if the sample is received by 9 AM at our Dubai Healthcare City laboratory.
3. Why is the CD22 marker crucial for planning my targeted therapy?
CD22 is a B-cell lineage-specific transmembrane protein. Its precise quantification directly guides eligibility for CD22-directed immunotherapies and helps track treatment response, disease progression, and the emergence of treatment resistance.
4. Do I need to prepare for the test and is home collection safe?
No special preparation like fasting is required. Our DHA-licensed mobile phlebotomists provide safe, ISO-certified cold-chain home collection from 8 AM to 11 PM for standard blood draws. If a bone marrow aspirate is needed, it must be scheduled at our partner hospital facility.
5. How will the CD22 results impact my ongoing oncology management plan?
Positive CD22 expression may qualify you for targeted treatment options. Changes in expression levels over time can signal remission or relapse, enabling your oncologist to make timely, data-driven adjustments to your personalized care strategy.
