Harmonized reference Ranges for Circulating Testosterone Levels in Men of Four Cohort Studies in the United States and Europe
https://watermark.silverchair.com/j...ASf19jyAlhaaUfS7FtHHGgMdMXkMHkdROz_DHVYwi7nDw
Conclusion:
- harmonized normal range in a healthy nonobese population of European and American Men, 19-39 years, is 264-916 ng/dl
- a substantial proportion of intercohort variation in testosterone levels is due to assay differences
- these data demonstrate the feasibility of generating harmonized reference ranges for testosterone that can be applied to assays, which have been calibrated to a reference method and calibrator
