Understanding Your Results

Results indicate CD19 protein presence, which is key for identifying B-cell malignancies.
📊

Positive

CD19 is expressed, suggesting B-cell lineage in malignancies like leukemia or lymphoma.

📊

Negative

No CD19 expression detected, which may indicate non-B-cell cancers or other conditions.

📊

Weak or Partial

Low CD19 expression; further testing may be needed for confirmation.

⚠️ When to Consult a Doctor:

If you experience persistent symptoms such as fever, weight loss, or lymph node swelling, consult an oncologist for evaluation.

Limitations

  • ⚠Cannot be used as a standalone diagnostic tool; must be correlated with clinical findings
  • ⚠May show false negatives in early-stage or low-expression cases
  • ⚠Not suitable for detecting all types of cancer

Risks & Considerations

  • ●Minimal risks from biopsy, such as infection or bleeding at the site
  • ●Rare allergic reactions to staining reagents

Interfering Factors

  • ●Poor tissue quality or insufficient sample
  • ●Improper fixation or processing of biopsy
  • ●Use of incorrect antibodies or staining protocols

Frequently Asked Questions

What is the Immunohistochemistry CD19 Test?
It is a test that detects CD19 protein on B cells using tissue samples, primarily for diagnosing cancers like leukemia and lymphoma.
Why is the CD19 test performed?
To identify B-cell malignancies, guide treatment decisions, and monitor cancer progression.
How is the sample collected for the CD19 test?
A tissue biopsy is taken, preserved in formal-saline or as a paraffin block, and sent to the lab.
What does a positive CD19 result mean?
It indicates CD19 expression, suggesting B-cell lineage in cancers like leukemia or lymphoma.
What does a negative CD19 result mean?
It means no CD19 is detected, which may point to non-B-cell cancers or other conditions.
Is the CD19 test used for diagnosing all cancers?
No, it is specific for B-cell malignancies and not applicable to all cancer types.
How long does it take to get CD19 test results?
Results are typically available in 5-7 days.
Is the CD19 test covered by insurance?
Coverage varies; check with your insurance provider as it may not be fully covered.
Are there any risks associated with the CD19 test?
Risks are minimal and mainly relate to the biopsy procedure, such as infection or bleeding.
Can the CD19 test detect other conditions besides cancer?
It is primarily for cancer diagnosis; positive results may also appear in some autoimmune conditions, but interpretation requires clinical context.
How accurate is the CD19 test?
It is highly accurate when performed on quality samples with proper protocols, but false negatives can occur.
What other tests are related to CD19?
Related tests include flow cytometry, bone marrow biopsy, and immunophenotyping.
