The normal ranges for gamma delta T-cells differes based upon racial background and the environment one was exposed to as a child (i.e. native country). White North Americans of Northern European descent have less than 3% of lymphs gamma delta T-cells. Black North American have higher values, as do Americans of Italian descent (I don't know why). South Americans (even of Northern European descent) and Asians have much higher numbers (up to 20% of lymphs). You will need to determine your own normal ranges.
