Description
Blood, NA, Fasting or Non Fasting: As suggested by doctor
Sample Required:
A tissue sample is required for this test, which is typically obtained through a biopsy.
Test Time:
Results are usually available within a few days to a week, depending on the laboratory.
Test Normal Range:
This test is not associated with a specific normal range as it measures the presence and distribution of CD20 protein in tissue samples.
What is the Test?
The CD20-IHC (Immunohistochemistry) Single Marker, Tissue Test is a laboratory test that examines tissue samples for the presence and distribution of CD20 protein. CD20 is a surface marker found on B-lymphocytes, a type of white blood cell involved in the immune system.
Test Procedure:
A healthcare provider will perform a biopsy to collect a tissue sample. This biopsy is typically conducted when there is suspicion of a condition affecting B-cells. The tissue sample is processed in a laboratory, embedded in wax, and cut into thin sections. The tissue sections are treated with antibodies specific to CD20, which bind to CD20 if it is present in the tissue. A pathologist examines the stained tissue sections under a microscope to determine the presence and distribution of CD20.
When to Take the Test:
This test is typically taken when there is a suspicion of conditions involving B-cells, such as certain lymphomas, leukemias, or autoimmune disorders.
Who Should Take This Test:
Individuals who have symptoms, clinical findings, or medical history that raise suspicion of conditions affecting B-cells may undergo this test to aid in diagnosis.
Precautions for Exceptional Cases (Pregnancy etc.):
Pregnancy does not typically impact the suitability of this test. However, it is important to inform your healthcare provider if you are pregnant or have any specific medical conditions before the biopsy.
FAQs:
Q1: What conditions might prompt a CD20-IHC tissue test?
A: This test is often used in the diagnosis and classification of lymphomas, leukemias, and certain autoimmune diseases.
Q2: Are there any risks associated with the tissue biopsy procedure?
A: Biopsy procedures carry some risks, such as bleeding and infection. Your healthcare provider will explain these risks to you before the procedure.
Q3: Can this test definitively diagnose a specific disease?
A: While this test can provide important information, it is usually part of a larger diagnostic process that may include other tests and evaluations.
Q4: What happens if CD20 is detected in the tissue sample?
A: The presence of CD20 in tissue can be indicative of certain B-cell-related conditions. Further tests and clinical evaluation are often needed for a definitive diagnosis.
Q5: How soon are the findings available?
A: Results are typically available within a few days to a week, but the timeline can vary depending on the laboratory’s workload and procedures. The anticipated wait time will be disclosed to you by your healthcare professional.
