1. What is HCG Level Rise?

Human chorionic gonadotropin (HCG) is a hormone produced during pregnancy. Monitoring the rise of HCG levels can help assess early pregnancy viability. In normal pregnancies, HCG levels typically double every 48-72 hours in the first weeks.

2. How Does the Calculator Work?

The calculator uses the HCG rise formula:

Where:

• Initial HCG — Starting HCG level (mIU/mL)
• Days — Time elapsed since initial measurement
• Doubling Time — Expected time for HCG to double (hours)

Explanation: The formula projects future HCG levels based on the expected doubling pattern.

3. Importance of HCG Monitoring

Details: Tracking HCG rise helps evaluate early pregnancy health. Slower-than-expected rises may indicate ectopic pregnancy or potential miscarriage, while faster rises might suggest multiple gestation.

4. Using the Calculator

Tips: Enter initial HCG level in mIU/mL, days since measurement, and expected doubling time in hours (typically 48-72). All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is a normal HCG doubling time?
A: In early pregnancy, HCG typically doubles every 48-72 hours. After reaching 1,200-6,000 mIU/mL, the rise slows.

Q2: When should I be concerned about HCG levels?
A: If levels don't double in 3 days or decrease, consult your healthcare provider. However, single measurements are less meaningful than trends.

Q3: How accurate is this calculator?
A: It provides estimates based on typical doubling patterns, but individual variations occur. Always interpret results with medical guidance.

Q4: When is the best time to test HCG levels?
A: For comparison, tests should be done at the same time of day, 48+ hours apart, using the same lab if possible.

Q5: What if my levels are rising faster than expected?
A: Faster rises might indicate twins/triplets or other conditions. Ultrasound confirmation is needed for diagnosis.
