Interleukin-2 (IL-2) Blood Test

What is the purpose of this test?

The Interleukin-2 (IL-2) Blood Test measures the level of IL-2 in your blood, which is a protein produced by certain immune cells called T-cells. IL-2 plays a crucial role in regulating the immune response by promoting the growth and activation of T-cells. This test helps doctors understand how well your immune system is functioning and can provide valuable insights into various immune-related conditions.

Doctors use the IL-2 Blood Test to diagnose and monitor conditions where the immune system is either overactive or underactive. Elevated levels of IL-2 may indicate an overactive immune response, such as in autoimmune diseases like rheumatoid arthritis or certain allergic reactions. On the other hand, low levels of IL-2 can indicate immune suppression, which may occur in conditions like HIV/AIDS or after organ transplantation when immune function is deliberately suppressed to prevent rejection. By measuring IL-2 levels, doctors can tailor treatment plans to manage these conditions effectively.

Who should get this test?

The Interleukin-2 (IL-2) Blood Test should be ordered by individuals who need to assess their immune system function and diagnose certain health conditions. Here are the groups of people who would benefit from this test:

• Patients with suspected autoimmune diseases: Helps evaluate immune system activity and response.
• Individuals with cancer: To monitor immune system function during cancer treatment.
• People with organ transplants: Helps assess immune suppression levels to prevent rejection.
• Patients with HIV/AIDS: To monitor immune system function and response to antiretroviral therapy.
• Individuals with chronic infections: Helps assess immune response and activity against pathogens.
• People undergoing immunotherapy: To monitor immune response to treatment.

These individuals can benefit from an Interleukin-2 (IL-2) Blood Test to understand how their immune system is functioning and guide appropriate medical treatment and management of their health conditions related to immune system activity.

When should I order this test?

An Interleukin-2 (IL-2) Blood Test should be ordered when individuals show symptoms that suggest problems with their immune system or related health conditions. Here are some symptoms that may prompt this test:

• Persistent infections
• Autoimmune disease symptoms
• Unexplained weight loss
• Chronic fatigue
• Recurrent fevers
• Symptoms of cancer
• Symptoms of organ rejection

If you experience these symptoms, especially if they are chronic or severe, discussing them with your doctor can help determine if an Interleukin-2 (IL-2) Blood Test is appropriate to assess your immune system function and guide further diagnosis and treatment.
