Flow Cytometry: Lymphocyte Subset Enumeration - CD3, CD4, CD8, CD19, CD56, CD45

No, fasting is not required for this test. You can continue your regular diet and activities unless otherwise instructed by your doctor.

This test measures the number and percentage of different lymphocyte subsets (B cells, T cells, and NK cells) in your blood. Each subset plays a specific role in the immune response, and their relative and absolute numbers can provide information about immune function and potential disorders.

The frequency of this test depends on your specific health condition and treatment plan. Your doctor will provide guidance based on these factors.

Normal values can vary widely based on several factors, including your age, overall health, and the specific lab guidelines. Your doctor will interpret your results accordingly.

No special precautions are necessary for this test. However, you should always inform your doctor about any medications or supplements you're taking, as these may influence the test results.

Various factors, including viral infections, certain cancers, immunosuppressive therapy, and aging, can affect the test results. Some factors, such as diet and lifestyle, are modifiable, while others are not.

You should consult an immunologist or oncologist if your test results are abnormal. They can provide further evaluation and guide you towards appropriate treatment.

As this test involves drawing blood, it carries minor risks such as pain or bruising at the injection site, lightheadedness, and a slight risk of infection.

An abnormal result does not diagnose a specific disease but suggests a potential problem with the immune system. Further investigations may be required to identify the exact issue.

Yes, certain medications, particularly those that affect the immune system, can influence the test results. It's essential to inform your doctor about all medications and supplements you're taking.

While many disorders that affect the immune system, such as certain cancers, are not preventable, maintaining a healthy lifestyle can support overall immune health and potentially reduce the risk of some diseases.

Treatment options depend on the specific disorder. For instance, cancers are typically treated with surgery, radiation, and chemotherapy. Immune deficiencies may require immunoglobulin replacement therapy, immune-boosting medications, or even stem cell transplantation in severe cases.

Some genetic immune deficiencies can be detected before birth through prenatal testing. However, many conditions that affect these counts, such as cancers, typically develop later in life.

The impact on lifespan can vary greatly depending on the specific disorder, its severity, and the effectiveness of treatment. Early detection and appropriate management can improve prognosis and quality of life.

In our dynamic world, with the constant evolution of disease-causing organisms and increasing prevalence of conditions that affect the immune system, understanding your immune status is more important than ever. Remember, you are a key player in your healthcare journey, and knowledge is an indispensable ally. Always engage in open dialogue with your doctor, ask questions, and understand what your test results mean for your health. Your proactive involvement can make all the difference.
