* At 24 DPO, the average HCG level is 2637 mIU/ml, with a typical range of 540-10,000 mIU/ml.
Accordingly, the key to interpreting the true value of HCG measurements is to look at their progression. In general, the HCG level will double every two to three days in early pregnancy. Approximately 85 percent of normal pregnancies will have the HCG level double every 72 hours. However, as you get further along in your pregnancy and the HCG levels get higher, the expected doubling time increases.
