- HCG is not produced until implantation occurs (8-9 days after ovulation)
- HCG test will NOT be positive for 8-9 days after ovulation*** - HCG prevents involution of corpus luteum, the corpus luteum produces progresterone, the hormone that supports early pregnancy development
- False positive results may occur d/t: Molar pregnancies/cancer, HCG injections used for weight loss, HCG producing tumors
15
Q
Positive signs of Pregnancy are considered ABSOLUTE**
A
- Only 3 signs are POSITIVE/ABSOLUTE
- Auscultation of fetal heart tones ** — 10-12 wks by handheld doppler OR 20 wks by fetoscope/stethoscope
