What Are Natural Killer (NK) Cells?
Natural Killer (NK) cells are a vital part of your innate immune system. They are your body’s first responders—designed to detect and eliminate abnormal cells like cancer cells and virally infected cells before they spread.
But the number of NK cells alone isn’t enough. Their activity level matters far more. A person can have many NK cells, but if they’re not functioning well, your immune defence is still compromised.
Why Measure NK Cell Activity?
✅ Detect early signs of immune system decline
✅ Evaluate risk for cancer, chronic infections, and autoimmune conditions
✅ Understand how stress, aging, lifestyle, or medications are affecting your immunity
✅ Guide personalised stem cell or NK cell therapy protocols
What Makes Our Test Different?
Our NK Cell Activity Test is based on a non-radioactive, ELISA-based method that uses a small amount of whole blood (1ml) to assess your NK cells’ ability to produce Interferon-gamma (IFN-γ)—a key immune signalling molecule.
Unlike older methods that require radioactive isotopes or complicated cell separation, our test is:
🔬 Simple, accurate, and safe
⏱️ Results-ready within 24 hours
📦 Convenient for clinical use and follow-up

This test is recommended for:
-
🎗️ Cancer patients and survivors
-
🧠 Individuals with fatigue, chronic stress, or infections
-
👵 The elderly seeking immune health tracking
-
🌱 Patients planning for stem cell or NK cell-based therapy
-
👨👩👧👦 Anyone wanting to assess their baseline immune status
