Non-Malaysian citizens are subject to 6% SST, to be verified and paid at the counter before screening.
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.
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.
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.
