Fertility what is beta

It is also a commonly used parameter for monitoring the proper progression of gestation , as we know that the value should double every hours during the first few weeks of pregnancy.

Below you can see a table indicating hCG levels post-ovulation in a blood sample :. In this table, Beta hCG values are counted starting from the first day of your last missed period, meaning day 14 post ovulation. At URE Centro Gutenberg we ask patients to have their beta analysed 16 days following the egg retrieval.

We must always keep in mind that these values are meant to serve as a guide and that they can vary significantly from one woman to another. You must remember that a normal pregnancy may have low hCG levels and result in a perfectly healthy baby. Sometimes a beta value is low simply because some embryos have a slower implantation process. There are also other factors which may cause the beta value to be lower:. If a beta value is higher than normal we cannot always assume that this is indicative of a multiple pregnancy ; rather, we must wait for confirmation through an ultrasound scan.

There is no single hCG level or cut-off that defines a normal pregnancy. The beta hCG will vary based on the type of embryo you transferred was it fresh? In general, a beta hCG level of over is generally considered a good, positive result.

But what's more important than the absolute beta number is the rate of increase over time it should double every 48 hours. The higher the percentage of rise in hCG drawn two days following the initial beta, the better the chances for success. What's more important than the absolute beta number is if the number increases substantially over time. What should the hCG level be 12 days after embryo transfer?

Data from study of pregnancies after IVF. Data from study of IVF participants. Beta hCG levels were taken 12 days after an embryo transfer. What does a high beta hCG mean? What does a low beta hCG mean? Can beta hCG levels predict singleton or twins? What if beta hCG is not rising or doubling? A failed transfer is devastating. Is it true that girl embryos have higher beta hCG?

What are normal hCG results throughout pregnancy? Simple right? Well truth is, no, it may not be that cut and dried.

Sometimes, even though the timing is right, the result comes back at less than What does a low beta result mean? This result does tell us that at a point in time the embryo began to implant.

And it may or may not continue to do so. Where does that leave you? This timing is chosen because if implantation is progressing normally, the level of hCG in blood should double in value every two to three days. And of course, this is what we hope to see. Once the hCG level reaches and ideally, exceeds 50, we can confirm a biochemical pregnancy the first milestone and will continue to monitor your progress.

On the other hand, we may find that the hCG level is not rising and implantation has been interrupted for any number of reasons. As in natural conception, sadly not all embryos are destined to lead to pregnancy and babies. And then? If your hCG level is falling, we will ask you to attend for a blood test each week until it is negative hCG no longer detected.

Even though the cycle was not successful, it is important to confirm that your body has completely recovered and everything is back to normal.
