IHC - CD21

The IHC - CD23 test, or immunohistochemistry for CD23, is a diagnostic test that looks for the presence of CD23, a protein that plays an essential role in the regulation of the immune response, especially in B-cell growth and differentiation. This protein is generally found on mature B cells, activated macrophages, eosinophils, and platelets.

CD23 is also the low-affinity receptor for the Fc region of IgE antibodies. Therefore, it plays a vital role in allergy and asthma pathogenesis. The abnormal expression of CD23 is also associated with certain types of leukemia and lymphoma, making the IHC - CD23 test a valuable tool in diagnosing these conditions.

What is the purpose of the IHC - CD23 test?

The IHC - CD23 test is used to detect the presence of CD23 protein in tissue samples, which can help diagnose certain types of leukemia and lymphoma and monitor allergic conditions.

What does a positive result mean?

A positive result indicates the presence of CD23 protein in the tissue sample. This can be a sign of certain types of leukemia or lymphoma or could indicate an allergic condition, depending on the context and other test results.

Frequently Asked Questions

The tissue sample for the IHC - CD23 test is typically obtained through a biopsy procedure, which involves removing a small piece of tissue for examination under a microscope.

No, the IHC - CD23 test requires a tissue sample that needs to be collected by a healthcare professional and analyzed in a laboratory.

The turnaround time for the IHC - CD23 test results is typically 3-5 days, but it can vary depending on the laboratory.

The IHC - CD23 test can help diagnose certain types of leukemia and lymphoma where CD23 protein is overexpressed. It can also be useful in evaluating allergic conditions.

A negative result means that CD23 protein was not detected in the tissue sample. This could suggest the absence of conditions associated with overexpression of CD23, but your healthcare provider will interpret these results in the context of your symptoms and other test results.

The risks associated with the IHC - CD23 test are related to the biopsy procedure used to collect the tissue sample, which can include pain, bleeding, or infection at the biopsy site. The test itself does not have any risks.

Yes, in some cases, the IHC - CD23 test can be used to monitor disease progression or the efficacy of certain treatments, particularly in leukemia and lymphoma cases.

The IHC - CD23 test is often performed alongside other tests, such as other immunohistochemistry tests, flow cytometry, or molecular tests, to provide a comprehensive understanding of the disease.

No special preparation is required for the IHC - CD23 test.

The IHC - CD23 test may provide prognostic information in certain cases, especially in conditions where CD23 expression levels are associated with disease severity or outcome.

A13: Yes, the IHC - CD23 test does not pose any risk to pregnant or breastfeeding individuals. However, any biopsy procedure carries a risk, so you should discuss these with your healthcare provider.

A positive IHC - CD23 test means that CD23 protein is present in the tissue sample. This can be a sign of certain types of cancer, but your healthcare provider will consider these results alongside other diagnostic tests and clinical information.

Other tests such as flow cytometry or molecular tests can provide similar information to the IHC - CD23 test. The choice of test depends on the suspected condition, the available facilities, and the doctor's preference.

Yes, the IHC - CD23 test does not interfere with any implanted medical devices, including pacemakers.

The pain associated with the IHC - CD23 test comes from the biopsy procedure used to collect the tissue sample. This pain is typically minimal and short-lived.

The accuracy of the IHC - CD23 test depends on the quality of the tissue sample and the procedures used in the lab. When performed correctly, it is considered highly accurate.

The IHC - CD23 test results are not typically affected by medications. However, it is important to share all medication information with your healthcare provider.

Yes, your IHC - CD23 test results are confidential and are shared only with your healthcare provider.
