<p><b>OBJECTIVE</b>To assess the value of monitoring serum human chorionic gonadotropin beta-subunit (beta-HCG) level changes in early diagnosis of ectopic pregnancy.</p><p><b>METHODS</b>Totalling 106 cases of ectopic pregnancy and 69 cases of threatened abortion were included in the study. Blood samples were collected to examine beta-HCG levels, which was repeated 2-3 days later.</p><p><b>RESULTS</b>Initial serum beta-HCG levels of the women with ectopic pregnancy and different were significantly lower than those in women with threatened abortion (P<0.05), and the increment rate of serum beta-HCG in the former was also significantly lower (P<0.05).</p><p><b>CONCLUSION</b>Compared with single-time serum beta-HCG detection, dynamic monitoring of serum beta-HCG provides more important and reliable evidence for early diagnosis of ectopic pregnancy. Transvaginal ultrasonography and in should also be considered in the clinical analysis.</p>
