In early pregnancy, normal hCG levels can vary widely among individuals. Generally, they range from about 5 to 426 mIU/mL in the first 4 weeks of gestation. By the 4th to 5th week, levels typically rise to between 18 and 7,340 mIU/mL. These levels continue to double approximately every 72 hours. Due to the wide range of normal levels, doctors usually look for a consistent increase in hCG levels rather than a single measurement to assess the viability of a pregnancy.
