متن کاملNasal bone length throughout gestation: normal ranges based on 3537 fetal ultrasound measurements.
OBJECTIVE To establish normal ranges for nasal bone length measurements throughout gestation and to compare measurements in two subsets of patients of different race (African-American vs. Caucasian) to determine whether a different normal range should be used in these populations. METHOD Normal nasal bone length reference ranges were generated using prenatal measurements by a standardized tec...
متن کاملA Description of Reference Ranges for Organic Acids in Urine Samples from A Pediatric Population in Iran
Background: Organic acids refer to a family of compounds that are intermediates in a variety of metabolic pathways. Many organic acids are present in urine from clinically normal individuals. Elevated levels of urine organic acids cause to the organic acidurias, disorders in which some metabolic pathways in organic acid metabolism are blocked. The present work identified major and minor urinary...
متن کاملMultisite bone ultrasound measurement on North American female reference population.
The Sunlight Omnisense is a portable quantitative ultrasound device that measures speed of sound (SOS) at multiple skeletal sites and therefore has the potential to provide a more complete assessment of an individual's overall fracture risk than single-site measurements such as the calcaneus. To provide a robust normative female database, 545 healthy Caucasian women ages 20-90 were recruited at...
