The placenta makes hCG and a blood test can first detect the hormone about 11 days after you conceive. In a typical pregnancy, your hCG levels double every 72 hours. This hour period increases to about every hours as you get further along. The American Pregnancy Association APA cautions against "making too much of hCG numbers" because women with low numbers can go on to have a normal pregnancy and a perfectly healthy baby.
Slow-rising hCG doubling times can be a possible sign of miscarriage or symptom of ectopic pregnancy , but this is not always true.

Blood Sciences Test
Human chorionic gonadotropin hCG is a pregnancy hormone secreted by the placental synctiotrophoblast cell layer that has been linked to fetal growth and various placental, uterine and fetal functions. In order to investigate the effects of hCG on clinical endpoints, knowledge on reference range RR methodology and determinants of gestational hCG levels is crucial. Moreover, a better understanding of gestational hCG physiology can improve current screening programs and future clinical management. We also investigated which pregnancy characteristics were associated with hCG levels. No considerable differences were found between RRs calculated in the general population or in uncomplicated pregnancies only. Maternal smoking, BMI, parity, ethnicity, fetal gender, placental weight and hyperemesis gravidarum symptoms were associated with total hCG. We provide gestational RRs for total hCG and show that total hCG values and RR cut-offs during pregnancy vary depending on pregnancy dating methodology.
