Hysteroscopy was useful in managing 5 patients with a possible ectopic pregnancy but with nonrising hCG levels below the threshold for ultrasound diagnosis. Two patients had an ectopic pregnancy, 2 patients had a threatened abortion, and 1 patient had an incomplete abortion....
However, the cut-off value of E2 level that significantly affects birthweight is unknown, and there is no definite conclusion regarding this level. Our study aimed to explore the threshold of the effect of E2 levels on birthweight. Design A retrospective cohort study of 1846 samples was ...
阴道超声联合血清β ＨＣＧ、ＰＡＰＰ Ａ诊断异位妊娠的诊断准确率明显高于单纯阴道超声。综上所述，异位妊娠患者的血清β ＨＣＧ、ＰＡＰＰ Ａ水平与同期正常妊娠者相比差异明显，可将作为协助诊断早期异位妊娠的临床指标，血清β ＨＣＧ、ＰＡＰＰ Ａ联合阴道超声能够进一步提升早期异位妊娠的诊断准确率，对于早期...
The AQT had a higher hook threshold than the i-STAT 1 and scored higher in the usability assessment. Although serum is not validated for use on either instrument, laboratory values correlated well with both POCT devices. Strengths The number of factors considered, the prospective sample ...

To determine an optimal detrimental threshold of P levels, ROC analysis was used. The area under curve (AUC) 0.58 (95% confidence interval: 0.53–0.63) was found to be significant (p = 0.002). The cut-off value of serum P on hCG day was found to be 1.00 for sensitivity and specificit...
[24]. When serum FSH level falls below the threshold level of the follicle, then that particular follicle becomes susceptible to apoptosis, resulting in atresia. On this basis, the serum FSH levels should fall during coasting when gonadotrophins are withheld, and this in turn can influence ...
patients were then divided into five distinct groups according to their serum progesterone levels on the day of hCG trigger: <1.0, 1.0–1.5, 1.5–2.0, 2.0–2.5, and ≥2.5 ng/mL. The cut-off levels were chosen to provide equal intervals focused around the threshold values used across prev...
The ROC curve analysis showed that for clinical pregnancy, the cutoff value was 482 mIU/mL for PGT patients, with the sensitivity of 93.7%, specificity of 100%, positive predictive value (PPV) of 100%, and area under the ROC curve (AUC) of 0.984. The threshold for clinical pregnancy in...
(NPV) of 85%. Women who had a hCG rise above this threshold had a risk of an ectopic pregnancy of 6.5%. Raising the hCG increase to 100% had a sensitivity of 55%, specificity of 95%, PPV of 86% and NPV of 80%, with an ectopic risk of 2.6%. An hCG increase of only 33% ...
