The inter-examiner reliability of fundal height measurements is essential in settings where patients are not examined by the same clinician at each prenatal visit. This preliminary study evaluated the inter-examiner reliability of two fundal height measurement techniques: tape measure and calliper. Four examiners obtained both measurements from 22 subjects who were between 25 and 30 weeks of gestation. The cumulative percentage of differences of less than or equal to 1.0, less than or equal to 2.0, and less than or equal to 3.0 cm for the four examiners was 13.6%, 13.6%, and 54.5% for tape measurements and 9.1%, 45.5% and 59.1% for the calliper measurements, respectively. The mean range of differences between the four examiners for the tape measure and calliper techniques were 3.68 and 3.31 cm, respectively. Clinicians are advised to be cautious in their interpretation of fundal height measurements in situations where the measurements are obtained by multiple examiners.
在每次产前检查并非由同一位临床医生对患者进行检查的情况下，宫高测量的检查者间可靠性至关重要。这项初步研究评估了两种宫高测量技术（卷尺和卡尺）的检查者间可靠性。四名检查者从22名妊娠25至30周的受试者身上获取了这两种测量值。卷尺测量中，四名检查者测量值差异小于或等于1.0 cm、小于或等于2.0 cm和小于或等于3.0 cm的累积百分比分别为13.6%、13.6%和54.5%；卡尺测量中，相应的累积百分比分别为9.1%、45.5%和59.1%。卷尺和卡尺技术的四名检查者间测量值差异的平均范围分别为3.68 cm和3.31 cm。建议临床医生在多名检查者进行宫高测量的情况下，对测量结果的解读要谨慎。
