Natural Killer Cell and Activated T-Cell Test

This test provides several measurements related to the immune system including Natural Killer Cells (NK). Natural Killer Cells (NK Cells) are a type of lymphocyte, or white blood cell, which play an important role in the body's immune system.  NK cells help to kill tumor cells or cells infected with a virus.  NK cells are identified and differentiated from other types of immune cells by certain antigens called CD proteins.  NK cells are CD56 positive and CD3 negative.  The measurements in this test can help assess the level of NK cells as well as their state of activation.  Results for this test should be interpreted by a person's doctor.

This test includes:

  • Percentage CD3+
  • Absolute CD3+
  • Percentage CD3+CD25+ (IL-2 Receptor)
  • Absolute CD3+CD25+
  • Percentage CD3-CD56+ (NK)
  • Complete Blood Count (CBC)

This test can be useful in diagnosing or monitoring treatment to conditions such as leukemia, viral hepatitis, and HIV.

Turnaround for this test is typically 2-4 business days.

Note: Result turn around times are an estimate and are not guaranteed. Our reference lab may need additional time due to weather, holidays, confirmation/repeat testing, or equipment maintenance.
