The NK Cell Activity Test is a diagnostic blood test used to evaluate the functional ability of natural killer (NK) cells, a key part of the innate immune system. NK cells are responsible for detecting and destroying abnormal cells, such as those infected by viruses or undergoing malignant transformation. By measuring how effectively these cells respond to threats, the test provides an important indication of immune activity and responsiveness. It is particularly relevant in cases involving chronic infections, immune system disorders, or cancer-related conditions.

This test offers insight into immune performance that standard blood tests may not reveal. Low NK cell activity may suggest a weakened immune defense, while elevated activity may indicate the presence of immune overactivation or imbalances. Monitoring NK cell activity is useful in preventive care, in tracking immune status during recovery, or in managing long-term health conditions involving the immune system. The results can help guide further evaluations or wellness strategies aimed at improving immune resilience and overall balance.

NK Cell Activity Test is a straightforward, non-invasive process that begins with the collection of a blood sample, usually from a vein in the arm. The procedure typically takes about 10 to 15 minutes and is similar to a standard blood draw. After collection, the blood is sent to a laboratory where natural killer (NK) cells are separated using a method called density gradient centrifugation, which isolates specific immune cells known as peripheral blood mononuclear cells (PBMCs). These cells are then exposed to target cells or stimulants to assess the NK cells' ability to respond. The test measures how actively these immune cells can destroy abnormal cells or produce important immune-signalling proteins called cytokines. The results help evaluate the functional strength of the immune system.

There is no downtime after the procedure, and normal daily activities can be resumed immediately. As it only involves a standard blood draw, no recovery time or special aftercare is needed.

1. Consultation will be conducted with the doctor.
2. Blood samples will be taken.
3. Blood samples will be sent to the laboratory for analysis.
4. Follow up session will be scheduled by the doctor for the results.

<Advantages>
· Detects early signs of immune weakness
· Tracks changes in immune activity
· Supports recovery from illness
· Improves overall understanding of body’s immune system

<Limitations>
· Results may vary depending on condition and lifestyle habits

· Avoid alcohol consumption and strenuous exercise 1 day before test
· Fasting is required for at least 8 hours prior to the blood test

Q1: How soon will I get the NK Cell Activity Test result?
A1: The results of NK Cell Activity Test usually take 3 to 7 days. The doctor at our affiliated clinic will schedule a follow up appointment to explain the results and whether any further tests or treatments are needed.

Q2: Is NK Cell Activity Test painful?
A2: NK Cell Activity is not painful; most patients feel a slight pinch during the injection for a blood sample.

Q3: Can NK Cell Activity Test be used for people with fatigue?
A3: Yes, NK Cell Activity Test can be helpful in understanding immune issues in patients with chronic fatigue or frequent unexplained tiredness, especially if patients also get sick often.

Q4: Is there any downtime after NK Cell Activity Test?
A4: There is no downtime after NK Cell Activity Test. Patients can return to their daily activities, work, or errands right after the test.

Q5: Can NK Cell Activity Test be used to detect specific diseases?
A5: No, NK Cell Activity Test does not diagnose a specific disease. Instead, it checks immune performance, which may help doctors explore reasons behind repeated infections, inflammation, or other health issues.
