What is beta-hCG?
A hormone from the placenta detected in blood/urine to confirm pregnancy.
Levels vary widely
In viable early pregnancy, values often rise over 48–72 hours—but one number alone is not diagnostic.
Seek care for
- One-sided pain, dizziness (possible ectopic pregnancy).
- Bleeding with pain.
- Abnormal trends with symptoms—needs ultrasound and serial labs.
Caution
Avoid comparing your result to online forums; interpretation is clinical.
