Assessing the most effective times of day to take urine tests among pregnant women
October 15, 2014
Dr.
Mark Walker
has published a paper in the Journal of Exposure Science and Environmental concerning the use of urine tests taken from women during pregnancy to analyze levels of phthalates and bisphenol A (BPA). BPA is thought to disrupt normal hormone levels and development in fetuses. Traditionally, studies have relied on single spot urine analyses to assess exposure; ignoring variability in concentrations throughout a day or over a longer period of time. Dr. Walker and his team compared BPA and phthalate metabolite results from urine samples collected at five different time points. Dr. Walker concluded that a more accurate way to estimate average exposure across a pregnancy is to do more than one measurement at different times of day, rather than a single spot measurement.
