High HCG Levels Were a Clue to My Pregnancy

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. Furthermore, we identify different pregnancy characteristics that influence total hCG levels considerably and should therefore be accounted for in clinical studies.

Possible Meanings of a High hCG Level in Pregnancy

Back to Ectopic pregnancy. It can be difficult to diagnose an ectopic pregnancy from the symptoms alone, as they can be similar to other conditions. If you have the symptoms of an ectopic pregnancy and a positive pregnancy test, you may be referred to an early pregnancy assessment service for further testing. An ectopic pregnancy is usually diagnosed by carrying out a transvaginal ultrasound scan.

The probe is so small that it’s easy to insert and you won’t need a local anaesthetic.

Indeed, similar to findings by Ball et al. Most likely, this effect is a cumulative smoking effect considering that we also found a strong dose-dependent association between the number of cigarettes smoked and total hCG decrease. Prenatal smoking has consistently been associated with an increased risk of small for gestational age children and low placental weight.

It is likely that the effects of prenatal smoking on birth weight of the newborn are at least in part caused by a decrease in hCG levels as it has been shown that prenatal smoking leads to an increase in apoptosis of synctiotrophoblast cell layer [ 44 ]. Future studies should investigate to what extent hCG contributes to the changes in fetal growth and birth weight. Interestingly, in particular the effects of smoking, but also the effects of other characteristics seemed to be more pronounced in our study compared to other studies [ 16 — 18 , 20 , 21 , 43 , 45 ].

In turn, this could suggest that BMI, smoking, parity, ethnicity, child gender and placental weight have differential effects on specific types of hCG such as nicked or hyperglycosylated hCG. To our knowledge, this is the only study which reports RRs for total hCG during pregnancy apart from the manufacturer of the assay that we used, which reported on pregnant women [ 46 ].

Furthermore, we are the first to report the associations between detailed maternal and fetal characteristics and total hCG levels during pregnancy. We were, however, limited by the fact that LMP and the menstrual cycle, placental weight and vomiting symptoms were only available in a subset of women. Also, the number of women with availability of total hCG measurements varied for each gestational week and therefore reference range determinations were not equally reliable throughout gestation, particularly during very early and the third trimester of pregnancy.

Potential differences in formulas used to determine gestational age based on ultrasound data may also underlie some of our results and warrant further research. In conclusion, we provide data on total hCG reference ranges during pregnancy from a large prospective population-based cohort and identified that these may considerably differ according to pregnancy dating methodology.

Before becoming pregnant I knew absolutely nothing about hCG, a hormone technically known as human chorionic gonadotropin. Although what I didn’t know didn’t hurt me, having a little insight would have sure explained a lot! As the very first indicator of pregnancy, this hormone can be found in the blood within 11 days of conception. Or, if you’re a bit more patient and can wait days, you can pee on a stick at home as it is present in urine that quickly.

Though there are charts showing normal levels , you shouldn’t take them too seriously or use them to date a gestational age because they can vary widely. In fact, your levels may not even be tested without signs of a possible problem, like bleeding, severe cramping, or a history of miscarriage — which was my situation.

HCG Levels: What They Tell You About Your Pregnancy

It is the hormone that many at-home pregnancy tests are designed to detect. Human chorionic gonadotropin is known as a pregnancy hormone as it’s produced in large amounts when you are pregnant. Early on in your pregnancy, the embryo starts to make more hCG as well as other hormones like estrogen and progesterone. These hormones help build up the lining of the uterus and send signals to the ovaries to stop releasing eggs, stopping your period.

HCG blood test – quantitative

HCG levels are an important indicator of the health and viability of an early pregnancy. HCG, or human chorionic gonadotropin, is one of the major pregnancy hormones. Once implantation occurs , the placenta begins to form and secrete hCG. However, hCG levels become meaningful once the placenta begins to secrete it in high amounts.

Human chorionic gonadotropin (hCG) is a hormone that can be detected in your urine and blood when you’re pregnant.

If your hCG level is high during pregnancy, it could be due to a variety of factors. It can be detected via a blood test roughly 11 days after conception and via a urine test approximately 12 to 14 days after conception. The hCG level usually reaches its peak between the second and third months of pregnancy and then drops. Determining what, exactly, constitutes a “high” hCG level can be difficult because the normal range of hCG levels in early pregnancy is wide, and hCG levels can rise and fall at different rates.

A high hCG level could indicate a few different things, most of which are not concerning. Molar pregnancies are believed to result from a genetic mistake in the fertilizing sperm or egg, which causes the cells that would typically develop into a fetus to grow into a non-cancerous mass instead. If you are having a molar pregnancy, your doctor will usually be able to determine that the pregnancy is not viable after 12 weeks when there is no fetal movement or heart tone.

A sonogram and pelvic exam will confirm a diagnosis. Signs and symptoms of a molar pregnancy can include high blood pressure, intense nausea or vomiting, anemia, hyperthyroidism, fast uterine growth, preeclampsia , ovarian cysts, the passage of the tumor through the vagina, and vaginal spotting or bleeding that’s dark brown or bright red. After a molar pregnancy, you may have to wait six months to a year to conceive again.

Sometimes, after the molar tissue is removed, it can keep growing and cause complications, such as vaginal bleeding and even a rare form of cancer. They will test your hCG levels every couple of weeks until the levels go down to zero, and every couple of months thereafter.

What you can’t see on this picture are the changes going on in your bloodstream. Within the first few days of your baby-to-be’s development, your body begins to produce and circulate human chorionic gonadotropin hCG , the so-called “pregnancy hormone. Over the next few days, this sac will grow at a rate of 1 mm daily.

As it develops, the levels of hCG will grow proportionately, too. The hCG levels will double every few days, and this increase is thought to be the reason many women feel nauseous. These hormones flood your entire body — not just your uterus. Because hCG levels are directly related to the growth of the gestational sac, your health care provider will be taking a close look at the hCG levels in your bloodstream.

Too high or too low of hCG levels might mean there is a problem with the pregnancy. Keep in mind that ultrasounds are usually not performed this early in a pregnancy—you’re getting an exclusive sneak peek here!
