Flow Cytometry: Lymphocyte NK Cell Enumeration (CD3, CD19, CD56, CD45)

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

The test quantifies the number and percentage of NK cells in your blood. These cells play a significant role in the body's defense against infection and cancer.

The frequency of this test will depend on your specific health condition and the treatment plan. Your doctor will guide you based on these factors.

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

No special precautions are necessary. However, remember to inform your doctor about any medications or supplements you're taking, as these may impact the test results.

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

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

Treatment will depend on the specific disorder. For instance, cancers are typically treated with a combination of surgery, radiation, and chemotherapy. Immune deficiencies may require immunoglobulin replacement therapy, medications to boost the immune system, 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.
