Comparison of specific gravity and creatinine for normalizing urinary reproductive hormone concentrations.


BACKGROUND Specific gravity (SG) may perform as well as creatinine (CR) correction for adjusting urinary hormone concentrations, as well as offer some advantages. We compared the two methods and applied them to US and Bangladeshi specimens to evaluate their use in different populations. METHODS Pearson correlations between serum concentrations and SG, CR… (More)
