Short Description

CD21 strongly stains the cytoplasm and membranes of the follicular dendritic cells and the membranes of a subset of the mantle zone lymphocytes. Follicular dendritic cells form a basket-weave meshwork in the germinal centers of lymphoid follicles, where they present antigens to B cells. Diagnostically CD21 may be useful to support a diagnosis of Follicular dendritic cell sarcoma or to confirm the presence of lymphoid follicles.

IMMUNOHISTOCHEMISTRY CD21 Test: Cost, Symptoms, and Diagnosis

IMMUNOHISTOCHEMISTRY CD21 test is a diagnostic tool that is used to analyze the level of CD21 protein in a patient's blood. This protein is also known as complement receptor 2, and it plays an essential role in the immune system. The test is performed using a sample of the patient's blood, and it is often ordered by doctors to diagnose certain conditions related to the immune system. In this blog, we will discuss the cost, symptoms, and diagnosis of the IMMUNOHISTOCHEMISTRY CD21 test.

• Repeated infections that do not respond to treatment

If you are experiencing any of these symptoms, it is essential to seek medical attention to determine the underlying cause.

Diagnosis

IMMUNOHISTOCHEMISTRY CD21 test is ordered by doctors to diagnose conditions that affect the immune system. The test is often used to diagnose conditions such as:

• HIV
• Autoimmune diseases, such as lupus
• Cancer of the lymphatic system
• Bacterial infections
• Viral infections

The test is performed using a sample of the patient's blood, and the results are typically available within a few days. If the results show that the patient has a low level of CD21 protein, it may indicate that there is a problem with their immune system.

Cost

The cost of the IMMUNOHISTOCHEMISTRY CD21 test may vary depending on several factors, such as the location of the testing facility, the type of insurance coverage, and the specific laboratory that performs the test. In India, the cost of the test is typically around INR 3000.

Conclusion

The IMMUNOHISTOCHEMISTRY CD21 test is a diagnostic tool that is used to analyze the level of CD21 protein in a patient's blood. The test is often ordered by doctors to diagnose conditions that affect the immune system. If you are experiencing symptoms that may indicate a problem with your immune system, it is essential to seek medical attention to determine the underlying cause. The cost of the test may vary depending on several factors, but in India, the cost is typically around INR 3000.
