As pregnancy tests, quantitative blood tests and the most sensitive urine tests usually detect hCG between 6 and 12 days after ovulation. However, it must be taken into account that total hCG levels may vary in a very wide range within the first 4 weeks of gestation, leading to false results during this period.
1 In 85% of normal pregnancies, the hCG level will double every 48 â 72 hours. 2  As you get further along in pregnancy and the hCG level gets higher, the time it takes to double can increase to about every 96 hours.3  Caution must be used in making too much of hCG numbers. An hCG level of less than 5mIU/ml is considered negative for pregnancy, and anything above 25mIU/ml is considered positive for pregnancy. 2  The hCG hormone is measured in milli-international units per milliliter (mIU/ml).
