Monitor pregnancy health with our HCG calculator - determines hormone doubling time between tests. Includes medical reference ranges and visual trend analysis.

What is It?

A specialized tool that calculates Human Chorionic Gonadotropin (HCG) hormone doubling time between two blood tests, helping monitor early pregnancy health and embryo development.

Key Features

  • Doubling Time Calculation: Determines if HCG levels are rising appropriately
  • Visual Trend Analysis: Charts your HCG progression
  • Medical Reference Data: Shows typical ranges by pregnancy week
  • Clinically Validated: Based on OB-GYN recommended formulas

The Formula

Doubling Time (hours) = [Time Difference × log(2)] / log(HCG2 ÷ HCG1)

Where:

  • HCG1 = First test value (mIU/mL)
  • HCG2 = Second test value (mIU/mL)
  • Time Difference = Hours between tests

How to Use

  1. Enter Test Results: Input your two HCG values and test dates
  2. Calculate: The tool automatically computes doubling time
  3. Interpret Results:
    • Normal: 48-72 hour doubling time
    • Optimal: <48 hours
    • Concern: >72 hours (consult your doctor)

FAQs

Q: How accurate is this calculator?
A: Mathematically precise but doesn’t replace medical advice. Always consult your healthcare provider.

Q: When should I get HCG tests?
A: Typically 48-72 hours apart during early pregnancy (weeks 4-8).

Q: What if my levels aren’t doubling?
A: Slightly slower doubling doesn’t always indicate problems, but consult your OB-GYN.

Terminology Explained

  • HCG: Pregnancy hormone produced by the placenta
  • mIU/mL: Milli-International Units per milliliter (standard measurement)
  • Doubling Time: Hours needed for HCG levels to double
  • LMP: Last Menstrual Period (used for pregnancy dating)
