Ovuloom📖 hCG
Human Chorionic Gonadotropin — the 'pregnancy hormone' produced by the placenta after implantation. It's what pregnancy tests detect.
In Detail
hCG is first detectable in blood 6-8 days after ovulation and in urine by 10-14 days. In early pregnancy, hCG doubles approximately every 48-72 hours. Levels peak at 8-11 weeks then decline. Normal first-trimester levels range from 5 to over 200,000 mIU/mL. Abnormal doubling times may indicate ectopic pregnancy or miscarriage risk. Beta hCG blood tests are more sensitive than urine tests and can detect pregnancy earlier.
