Natural Killer Cells (NKC)

This test measures the levels and function of natural killer (NK) cells, which are a type of white blood cell involved in immune responses. These measurements provide valuable information about the immune system's strength and functionality.

This test is done for several reasons:

• To evaluate immune system function and identify any deficiencies
• To investigate recurrent infections or suspected immunodeficiencies
• To assess the immune response to certain cancers
• To monitor the effectiveness of treatment for certain diseases
• To aid in diagnosing and managing certain autoimmune disorders

This test may be recommended if you have:

• Recurrent infections or suspected immunodeficiency
• A history of certain autoimmune disorders
• Suspected impaired immune function
• Been diagnosed with certain types of cancer
• Undergoing treatment for cancer or immunosuppressive therapy

The Normal Range for Natural Killer Cell absolute count is 100 400 cells/µL. Low NK cell count may indicate weakened immune function or certain medical conditions. High NK cell count may be associated with infections, autoimmune disorders, or certain cancers. Your doctor will interpret the results in the context of your medical history and other diagnostic tests.

• The test involves drawing a blood sample from a vein in your arm.
• A healthcare professional will clean the area with an antiseptic wipe and then insert a needle into a vein to collect the blood.
• You may feel a brief pinch or sting when the needle is inserted, but it's generally not painful.

• No fasting or special diet is required.
• Inform your doctor about any medications you are taking.
• Follow any specific instructions provided by your doctor.

• Complete Blood Count (CBC): This measures different components of blood, including red blood cells, white blood cells, and platelets.
• Additional immunological testing: Testing for specific antibodies or other immune system markers to further evaluate immune function.

NK Cell Count or NK Cell Function test

Impaired immune function refers to a weakened immune system that is unable to adequately protect against infections and diseases. Conditions such as immunodeficiency disorders, autoimmune diseases, certain cancers, and chronic infections can result in impaired immune function.
