Doubling Time

--

The doubling time is the number of days it takes for HCG levels to double.

Calculation Formula

Doubling Time (days) = log2(Follow-up HCG / Initial HCG) * 3.3

Where:
Initial HCG: The HCG level at the first test.
Follow-up HCG: The HCG level at the second test.
log2: The logarithm base 2.

  2. Enter the follow-up HCG level in mIU/mL.
  3. Enter the number of days between the two tests.
  4. Click the "Calculate" button to estimate the doubling time.

Understanding the Results

The calculator provides the estimated doubling time in days. A normal doubling time in early pregnancy is typically around 48 to 72 hours. A significantly longer doubling time may indicate a potential problem with the pregnancy.
