1. What is hCG Weeks Calculator?

The hCG Weeks Calculator estimates gestational age based on human chorionic gonadotropin (hCG) levels. hCG is a hormone produced during pregnancy that doubles approximately every 48-72 hours in early pregnancy.

2. How Does the Calculator Work?

The calculator uses the hCG weeks formula:

\[ Weeks = 2 + \frac{\log_{10}(hCG / 5)}{0.4} \]

Where:

\( hCG \) — Human chorionic gonadotropin level (mIU/mL)
\( \log_{10} \) — Base-10 logarithm
5 — Baseline hCG level
0.4 — Conversion factor
2 — Starting point in weeks

Explanation: The formula converts hCG levels to estimated gestational age based on the typical logarithmic growth pattern of hCG in early pregnancy.

3. Importance of hCG Monitoring

Details: hCG monitoring helps confirm pregnancy viability, estimate gestational age, detect potential complications like ectopic pregnancy or miscarriage, and track pregnancy progression.

4. Using the Calculator

Tips: Enter hCG level in mIU/mL. The value must be greater than 0. For best accuracy, use quantitative hCG blood test results rather than qualitative urine tests.

5. Frequently Asked Questions (FAQ)

Q1: How accurate is this calculation?
A: This provides an estimate based on typical hCG patterns. Individual variations occur, and ultrasound dating is more accurate for confirming gestational age.

Q2: What are normal hCG ranges by week?
A: hCG levels vary widely but typically range from 5-50 mIU/mL at 3 weeks, up to thousands by 5-6 weeks, and peak around 8-11 weeks.

Q3: When should hCG levels be measured?
A: Quantitative hCG tests are most useful in early pregnancy (first trimester) to confirm pregnancy progression and estimate gestational age.

Q4: What if my hCG level doesn't match the estimated weeks?
A: Consult your healthcare provider. Discrepancies may indicate dating errors, multiple gestation, or potential complications requiring medical evaluation.

Q5: Can this calculator diagnose pregnancy problems?
A: No, this is an estimation tool only. Always consult healthcare professionals for proper pregnancy monitoring and diagnosis.
