Assessment: Normal
Expected: 30-72 hoursFor hCG levels around 100 mIU/ml, doubling time of 2.0 days is normal.
Medical Disclaimer
This calculator provides estimates based on hCG test results. hCG levels vary significantly between individuals and pregnancies. Always consult with qualified healthcare providers for proper interpretation of test results and medical guidance. Abnormal results require immediate medical attention.

Understanding hCG
What is hCG?
Human Chorionic Gonadotropin (hCG) is a hormone produced by the placenta during pregnancy. It supports the corpus luteum, which produces progesterone to maintain the uterine lining and prevent miscarriage.
Functions of hCG:
- • Maintains corpus luteum function
- • Supports progesterone production
- • Prevents menstruation during pregnancy
- • Supports early fetal development
- • Used for pregnancy detection
Clinical Applications
hCG testing is essential for pregnancy monitoring, diagnosis of pregnancy complications, and assessment of certain medical conditions. Serial measurements provide valuable information about pregnancy viability.
Uses of hCG Testing:
- • Pregnancy confirmation
- • Ectopic pregnancy diagnosis
- • Miscarriage assessment
- • Multiple pregnancy detection
- • Gestational trophoblastic disease
- • Certain cancer monitoring
Important Considerations
Normal Patterns
- • Doubling every 48-72 hours early on
- • Peak around 8-11 weeks
- • Decline after first trimester
- • Wide individual variation
Concerning Signs
- • Slowly rising or plateau levels
- • Declining levels early in pregnancy
- • Extremely high levels
- • Levels not matching gestational age
