Age-Specific Reference Ranges of Prostate-Specific Antigen Among Saudi Men As a Representation of the Arab Population

Conclusions: PSA serum levels in Saudi men are lower than in other communities. Creating age-specific reference ranges could improve the sensitivity of the PSA tests by allowing the detection of treatable tumors in younger men if the threshold of 4.0 ng/mL is lowered. Furthermore, unnecessary biopsies among older men may be avoided if the threshold is increased.
