Understanding Pregnancy Test Strips: How They Work
Pregnancy test strips detect human chorionic gonadotropin (hCG), a hormone produced after implantation, in urine. Strips use antibodies that bind hCG, creating visible lines—control for validity, test for pregnancy.
Key facts:
- Sensitivity: 10–25 mIU/mL; lower detects earlier.
- Accuracy: >99% from missed period day (Cleveland Clinic 2025).
- Types: Midstream (pee on) or dip (cup urine).
hCG doubles every 48–72 hours, peaking at 8–11 weeks. Cleveland Clinic pregnancy tests Cleveland Clinic Pregnancy Tests.
