Diagnostic Test
B-hCG
Transvaginal Sonography
basis for endocrine assays of pregnancy
produced by syncytiotrophoblast
main function is to prevent involution of corpus luteum
Alpha subunit: identical to LH, FSH, TSH
Beta Subunit: used for pregnancy detection
B-hCG
Transvaginal Sonography
Gestational Sac
Pseudogestational Sac
Yolk Sac
Pregnancy of Unknown Location
Small anechoic fluid collection
1st sonographic evidence at 4-5 weeks
Implants eccentrically in endometrium
Gestational Sac
Fluid collection with in the endometrial cavity with an ectopic pregnancy
Pseudogestational Sac
brightly echogenic ring with anechoic center confirms with certainty an intrauterine location for the pregnancy
Seen at 5th week AOG
Yolk Sac
If equivocal findings
Serum serial hCG levels helps to differentiate
Pregnancy of Unknown Location
Embryo is seen as a linear structure adjacent to yolk sac with cardiac activity
After 6 weeks
Crown rump length is predictive of gestational age within 4 days
12 weeks
