Note: PSA Total values that fall below 4.0 nanograms per mililiter of blood (ng/ml) are generally considered “normal” although some physicians propose even stricter ng/ml values of 2.5 or less. This latter value may be particularly relevant to people that tend to be more predisposed to these conditions. While the debate in the literature continues about setting even more stringent lower limit values for the safe or normal zones, there is little or no argument about the seriousness of the negative meaning of ng/ml values of 10.0 and more. However, as one of the articles on the reading list below tells us, there is more to all of this than just interpreting the PSA scores. One has to also consider many other interrelated factors to make a conclusive determination. A Free PSA score, a Free/Total PSA value, PSA velocity, PSA density, age of the person, race, nutrition, and even sexual relations prior to blood test amongst them.
