An ectopic pregnancy can be a very serious, and even life-threatening, condition. Levels of hCG remain low during an ectopic pregnancy.
What is the hCG level for ectopic pregnancy?
Absence of an intrauterine gestational sac on abdominal ultrasound in conjunction with a β-hCG level of greater than 6,500 mIU per mL suggests the presence of an ectopic pregnancy.
Do hCG levels rise normally in ectopic pregnancy?
A b-hCG increase of <53% in 48 hours suggests abnormal pregnancy, either ectopic or failed intrauterine pregnancy. Abnormal rises in b-hCG only have 36% sensitivity and 65% specificity for detecting ectopic pregnancy. This is because ectopic pregnancies can have normally rising b-hCG levels 21% of the time.
Does hCG decrease with ectopic pregnancy?
During the week after treatment for an ectopic pregnancy, your hCG (human chorionic gonadotropin) blood levels are tested several times. Your doctor will look for a drop in hCG levels, which is a sign that the pregnancy is ending (hCG levels sometimes rise during the first few days of treatment, then drop).
How quickly do hCG levels drop after ectopic?
Studies of successful ectopic pregnancy treatment have shown that serum hCG declines with a half-life of approximately 30 to 64 hours. Depending on initial serum hCG level, the time until undetectable hCG levels can be as long as 6 to 8 weeks.
Does slow rising hCG always mean ectopic?
A low or slow-rising hCG level can be a sign of an ectopic pregnancy, but looking at hCG levels alone is not usually enough for a doctor to make the diagnosis. While a slow-rising or low hCG level can indicate an ectopic pregnancy, it does not mean that you are definitely experiencing one.
Can you see an ectopic pregnancy on ultrasound at 6 weeks?
How are they diagnosed? Trans-vaginal ultrasound examination is the best way to diagnose an ectopic pregnancy. An intra-uterine pregnancy can usually be seen by 5-6 weeks gestation or when the HCG level is >1500 IU/l. If it is not in the uterus, it may be ectopic.

How do I know if I’m having an ectopic pregnancy?
Often, the first warning signs of an ectopic pregnancy are light vaginal bleeding and pelvic pain. If blood leaks from the fallopian tube, you may feel shoulder pain or an urge to have a bowel movement. Your specific symptoms depend on where the blood collects and which nerves are irritated.
What causes slow rising hCG?
Slow-rising quantitative hCG levels, at least in early pregnancy, may be a sign of an ectopic pregnancy. Since a ruptured ectopic pregnancy can be dangerous, your doctor may recommend a transvaginal ultrasound to look for signs of an ectopic pregnancy.
Where is ectopic pain located?
The pain usually appears in the lower abdomen or pelvic region – often localized on one side of the body. It can feel dull or crampy, be continual or scattered, and possibly worsen with movement. As the ectopic pregnancy progresses, abdominal pain may become severe and sharp.
How can I check my hCG levels at home?
For some home pregnancy tests, you’ll hold an indicator stick directly in your urine stream until it’s soaked, which should take about 5 seconds. Other kits require that you collect urine in a cup and then dip the indicator stick into the cup to measure the hCG hormone level.
When does ectopic pregnancy happen?
The signs and symptoms of an ectopic pregnancy typically occur six to eight weeks after the last normal menstrual period, but they may occur later if the ectopic pregnancy is not located in the Fallopian tube.
What should hCG levels be at 5 weeks?
Typical hCG Results
5 weeks: 18 – 7,340 mIU/ml. 6 weeks: 1,080 – 56,500 mIU/ml. 7 – 8 weeks: 7, 650 – 229,000 mIU/ml. 9 – 12 weeks: 25,700 – 288,000 mIU/ml.
How soon can ultrasound detect ectopic?
Levels of this hormone increase during pregnancy. This blood test may be repeated every few days until ultrasound testing can confirm or rule out an ectopic pregnancy — usually about five to six weeks after conception.
Does methotrexate terminate ectopic pregnancy?
Methotrexate works by stopping the growth of the fertilized egg before a rupture occurs. Sometimes, methotrexate is combined with surgery to treat an ectopic pregnancy. In this case, the medicine removes fetal cells left behind after surgery.
