Stratified values are being transcribed from the cited source and are not yet published here. A single unstratified figure would be the least useful form of this information, so none is shown in the interim.
Published values vary by sex, age, time of collection, menstrual cycle phase and analytical method. The interval applicable to a patient's result appears on that patient's report.
