A result of less than 6% is considered low, 6-10% intermediate, and more than 10% is considered high. Ki-67: Ki-67 is a protein in cells that increases as they prepare to divide into new cells. A staining process can measure the percentage of tumor cells that are positive for Ki-67.
Is Ki67 expression in normal cells?
Ki-67 was first identified via an antibody raised against Hodgkin’s lymphoma cell nuclei (1). Because Ki-67 is generally expressed strongly in proliferating cells and poorly in quiescent cells (2), anti-Ki-67 antibodies are frequently used to detect proliferative cells in clinical studies (3, 4).

What does low Ki67 mean?
In general, if the Ki67 is between 0-2%, then we call it grade 1 or low grade. If it is between 2-20%, we call it grade 2 or intermediate grade. If it is > 20%, then it is grade 3 or high grade. The good, the bad, and the ugly. However, the devil is in the details.
