What is a good first beta hCG levels after IVF?
With detailed statistical analysis (ROC curve) they concluded that an hCG level of 76 mIU/mL was a suitable cut-off point for predicting viable pregnancy with 80% sensitivity and 82% specificity.
What is a good beta number after IVF?
A strong beta number at 17 days after fertilization (14dp3dt or 12dp5dt) would be over 200 mIU/mL (or IU/L, they are equivalent). One study of 523 IVF pregnancies found that betas over 200 IU/L at this time had the greatest chance of success.
How many days after FET Did you get a positive HPT?
In an IVF procedure, a pregnancy test is done after two weeks to check the results. After an embryo transfer procedure, it takes around 10-14 days to see the IVF results. In some IVF cycles, fresh embryos are transferred, while in other cases, frozen embryos can also be transferred to the uterus.

Can you have 0 hCG and be pregnant?
A pregnancy where there is little or no detectable HCG (human chorionic gonadotropin) in the mother’s system and even the fetus may go undetected by doctors, until delivery. HCG is the hormone that makes a home pregnancy test turn positive. A baby that produces very little amount of HCG might fail the pregnancy test.
Can a blood pregnancy test be wrong at 4 weeks?
Qualitative hCG tests can detect elevated levels of the pregnancy hormone. But the hCG levels in blood and urine do not shoot up immediately when a woman becomes pregnant. Therefore, a test performed too early might produce an inaccurate result.
What if my hCG is rising but not doubling?
If your hCG levels don’t come close to doubling after 48 to 72 hours, your doctor may have concerns that the pregnancy is at risk. Medically, this may be called a possible “nonviable pregnancy.” If your levels are dropping or rising too slowly, you’ll probably be sent for other testing as well.
Is it OK if hCG doesn’t double?
If your hCG levels aren’t exactly doubling but are still increasing, that’s a good sign. Because of these natural variations, hCG patterns alone cannot determine whether or not your pregnancy is viable. Hormone testing should always be followed up by an ultrasound before a diagnosis is made.
What should beta be at 4 weeks?
hCG Levels Chart by Week
| Pregnancy week | Range of hCG levels in milli-international units per milliliter (mIU/mL) |
|---|---|
| 3 weeks | 5–72 mIU/mL |
| 4 weeks | 10–708 mIU/mL |
| 5 weeks | 217–8,245 mIU/mL |
| 6 weeks | 152–32,177 mIU/mL |
When does your hCG stop doubling?
hCG levels usually consistently rise until around week 10–12 of your pregnancy, when the levels plateau or even decrease. This is the reason why pregnancy symptoms can be greater in the first trimester and ease off after this time for many women. In early pregnancy, hCG levels usually double every two to three days.
