Reproducibility of urinary phthalate metabolites in first morning urine samples.
Phthalates are ubiquitous in our modern environment because of their use in plastics and cosmetic products. Phthalate monoesters--primarily monoethylhexyl phthalate and monobutyl phthalate--are reproductive and developmental toxicants in animals. Accurate measures of phthalate exposure are needed to assess their human health effects. Phthalate monoesters have a biologic half-life of approximate...
متن کاملInfluence of first morning urine volume, fasting blood glucose and glycosylated hemoglobin on first morning urinary albumin concentration.
The aim of the present study was to evaluate the effect of first morning urinary volume (collected on three different non-consecutive days), fasting blood glucose (determined on the first and third days of urine collection), and glycosylated hemoglobin (determined on the first and third days of urine collection) on the albumin concentration in first morning urine samples collected on three diff...
متن کاملAge-related reference values for free amino acids in first morning urine specimens.
We determined age-related reference values for urinary free amino acids (in mmol/mol creatinine) in first morning urine specimens from 360 control subjects who were divided into nine age groups: birth to 1 month, 1-6 months, 6-12 months, 1-2 years, 2-4 years, 4-7 years, 7-10 years, 10-13 years, and older than 13 years. Except for taurine and 3-methylhistidine, the concentration of all the amino...
متن کاملTotal creatinine content of the first morning urine is independent of dietary change.
Our primary purpose in publishing the case reportcited in the two preceding letters was to suggest a technique for the determination of the lactate dehydrogenase isoenzymes that we have found helpful when the diagnosis of myocardial infarction is questionable. The improved reliability of the LD-isoenzyme test has been demonstrated in several recent publications (1-4). Our intent was not to exha...
متن کاملVariability of phthalate monoester levels in daily first-morning urine from adult women: a pilot study.
Phthalate exposure is ubiquitous and may affect child and adolescent health through both in utero exposure and direct exposure during childhood. Variability in exposure within women is not well documented. We analyzed 90 first-morning urine samples collected by ten reproductive-age women for phthalate metabolites and creatinine. Monoethyl [122 ng/mL (geometric mean concentration = 139 microg/g ...
