Beta hCG Doubling Calculator
Use this calculator to calculate the doubling time of two beta hCG samples by entering the values of the blood tests and the date and time of each test.
In many early pregnancies, the hCG level will double every 31 to 72 hours. As the pregnancy progresses, hCG levels rise and the doubling time increases.
hCG levels rise during the first 6 to 10 weeks of pregnancy then decline slowly during the second and third trimesters.
|Important! Please keep in mind there is a huge variation in "normal" hCG levels at any given time in a pregnancy. These numbers and times are provided only as a guideline. If you have any concerns please consult with your physician.|
