NK Cell Activity Test

Introduction

Natural Killer (NK) cells are a vital component of the immune system, responsible for recognizing and destroying virus-infected cells and cancer cells. The NK Cell Activity Test evaluates the killing ability of NK cells, providing a key measure of the body’s immune defense capacity.

Why Take an NK Cell Activity Test?

  • Immune health assessment: Determines the body’s natural defense against disease.
  • Cancer risk monitoring: Low NK activity is linked to higher cancer susceptibility.
  • Infection control evaluation: Important in chronic viral infections such as hepatitis B, C, and EBV.
  • Therapy monitoring: Used in follow-up for immunotherapy, chemotherapy, or radiotherapy.

Method & Workflow

A venous blood sample is analyzed to assess NK cell cytotoxicity against target cells. Common methods include flow cytometry and cytotoxicity assays. Results must be interpreted along with other immune parameters and clinical context.

Who Should Consider Testing?

  • Individuals with weakened immunity or recurrent infections
  • People at high risk for cancer or cancer patients
  • Patients undergoing immunotherapy, chemotherapy, or radiotherapy
  • Anyone interested in immune health and chronic disease prevention

Frequently Asked Questions (FAQ)

Q1: What does low NK activity mean?
A: It suggests weakened immune defense, increasing the risk of infections and cancer.

Q2: Is high NK activity always good?
A: Not necessarily. Overactive NK cells may be associated with certain autoimmune diseases.

Q3: Can NK activity replace cancer screening?
A: No. It cannot diagnose cancer alone, but it is a valuable marker for immune function and risk assessment.
