Will a vanishing twin (lost at 7 weeks) affect the results of first trimester Down's syndrome blood testing?

Will a vanishing twin (lost at 7 weeks) affect the results of first trimester Down's syndrome blood testing?

Unlikely: These tests rely on the active production of various markers in the blood and so a demised twin this early on will be unlikely to affect the test. These tests however, should be interpreted in the setting of a screening ultrasound to help better understand the risk. That being said, no test is ever 100% accurate, though they are useful. Consultation with a genetic counselor will help. ...Read more

Will a vanishing twin (lost at 7 weeks) affect first trimester downs syndrome testing with blood test and ultrasound?

Will a vanishing twin (lost at 7 weeks) affect first trimester downs syndrome testing with blood test and ultrasound?

Vanishing twin: No, it would not affect your test result. Ultrasound would show it for a while, but the developing twin will eventually grow big enough to hide it from view. ...Read more

Age 21 first pregnancy. Vanishing twin lost at 7 weeks. Nuchal translucency scan this week, so nervous! What are the chances that its high risk?

Age 21 first pregnancy. Vanishing twin lost at 7 weeks. Nuchal translucency scan this week, so nervous! What are the chances that its high risk?

Don't worry: It sounds like you are getting good care. Try not to worry as it is not good for you nor your pregnancy. Just wait and see what the tests show. Try to enjoy your pregnancy, and do what you can to stay healthy. Drink plenty of water, eat a healthy diet containing lots of fresh fruits and vegetables, walk 45 minutes every day, and take Prenatal vitamins containing Folic acid. ...Read more

Vanishing twin syndrome lost at 7 weeks. What is the likelihood that remaining twin will have something wrong with it?

Vanishing twin syndrome lost at 7 weeks. What is the likelihood that remaining twin will have something wrong with it?

Pretty small: The chances of a genetic defect in the remaining twin is very small as long as it continues to develop. On most occasions the surviving twin got the majority of the placental perfusion and that is why it is still present and hopefully growing. ...Read more

Vanishing twin syndrome (lost at 5+ weeks), what is the likelihood of the remaining twin having something wrong with it?

Vanishing twin syndrome (lost at 5+ weeks), what is the likelihood of the remaining twin having something wrong with it?

Increased risk LBW: Compared to singletons, the surviving twin of VTS is at slightly greater risk of premature delivery, low birth weight and, for twin loss after 8 weeks gestation there is an increased risk for cerebral palsy. Loss of a twin at five weeks greatly reduces the risk for the surviving twin to have any adverse consequences. ...Read more

Can vanishing twin be found if we wait a week?

Can vanishing twin be found if we wait a week?

Generally not.: If you are really early in the first trimester, poor imaging may be confusing and suggest vanishing twin, where there isn't any. In such cases, it never hurts to look again in a week to make sure the correct diagnosis is entertained. ...Read more

Could vanishing twin cause any risk to surviving baby?

Not really: This is not uncommon, that only one fetus of the two survive without any problems. Pregnancy needs monitoring however as high risk. ...Read more

Hcg levels dropped - vanishing twin, should I be concerned?

Aware: If this is what is happening I would say be aware, rather than be concerned. The outcomes are not guaranteed but they are often very good, this happens a lot. Best wishes. ...Read more

What is vanishing twin syndrome?

What is vanishing twin syndrome?

Demise of one fetus: Vanishing twin syndrome is the demise of one twin sometime during the pregnancy. One study suggested it occurred about 20-30% of twin pregnancies. Most commonly it occurs early in the pregnancy and generally the remaining fetus has a good outcome. Its' occurrence later in pregnancy can be associated with adverse maternal and fetal outcomes. ...Read more

What are the tests for vanishing twin syndrome?

None.: Vanishing twin syndrome is probably much more common that people think; it results in a singleton pregnancy and current evidence suggests it is rather the norm than the exception. No test can predict this, only serial prenatal sonograms can document it. ...Read more

Eggs splice, or the two fraternal twins suffer from vanishing twin syndrome and the twin literally absorbs the other twin, what does this mean?

Eggs splice, or the two fraternal twins suffer from vanishing twin syndrome and the twin literally absorbs the other twin, what does this mean?

Conjoined placenta: Unfortunately, the placenta often becomes shared between the twins and the one with the better access to the cotyledons of the placenta thrives and the other twin does not. An alternate scenario is when the two fraternal fetal twins are joined together but one does not develop as well as the other prior to placental development in the first trimester. ...Read more

At 12 weeks scan the ultrasound technician saw that the baby has penetrated the empty sac of the vanishing twin. How can this be?

Clarification: I would schedule a visit with your doctor to ask for clarification on the sonogram findings. This is such a specific question it requires someone to view the images of the sonogram to be able to interpret the results ...Read more

I'm 39 & 6 weeks preg. W/ twins. How concerned should I be about vanishing twin syndrome? What should I expect at my visit in 2 weeks. I'm really scared

I'm 39 & 6 weeks preg. W/ twins. How concerned should I be about vanishing twin syndrome? What should I expect at my visit in 2 weeks. I'm really scared

Worrying will not: Help the matter any. Vanishing of one of the twin is being recognized more often due to the common use of ultrasound in early pregnancy. I understand your being concerned, but that will not affect the outcome. Please see this site for information on this topic.

Lmp 3-31 on 4-20 + hpt. 4-24 hCG 303, on 4-30 hCG 173- 6hrs later hCG 197. Possible vanishing twin, or should I expect a m/c?

Likely miscarriage: When the HCG of pregnancy either plateaus or goes down, it's almost always an inevitable miscarriage. If it's appropriate, you may want to follow up with doctor for ultrasound or to follow HCG to zero (depending on your circumstances). Speak with your ob/gyn for guidance re your specific situation. Best of luck. ...Read more

At 12 weeks the ultrasound technician saw that my fetus has penetrated the empty sac of the vanishing twin. How could this be?

At 12 weeks the ultrasound technician saw that my fetus has penetrated the empty sac of the vanishing twin. How could this be?

Good question: I am not sure what the ultrasound technician may have meant if he/she really stated the surviving fetus has penetrated the empty sac of the vanishing twin. If he/she is implying that the membranes of the vanishing twin are somehow wrapping around the surviving fetus, then this is a situation that you would want to have clarified by a Maternal Fetal Medicine specialist. Discuss a referral. ...Read more

Cleft palate and vanishing twin, which is more common?

Cleft palate and vanishing twin, which is more common?

Vanishing Twin is: More common than isolated cleft palate. Vt may occur in up to 30% of multiple gestations, but we are detecting this more frequently because of better tests. Cleft palate incidence differs among races, but occurs in about 0.5 births per 1000. CP is most common in american indians, then japanese, chinese, whites, and blacks. CP has a genetic basis whereas twin births generally do not. ...Read more

After healthy heart rates are identified in identical twins, what is the probability of a vanishing twin?

After healthy heart rates are identified in identical twins, what is the probability of a vanishing twin?

Fairly common: A conservative estimate of frequency is that vanishing twin syndrome occurs in 21-30% of multifetal pregnancies. More commonly identified now that first trimester ultrasound is widely used. There are no known preventive measures since the loss usually occurs because of cord implantation abnormalities. Thanks for trusting HealthTap! ...Read more

Can a vanishing twin affect the results of genetic blood test in the first trimester?

Can a vanishing twin affect the results of genetic blood test in the first trimester?

No: If they were identical twins, they would share the exact same genetic information. So no it should not make any difference. If they were fraternal twins, still should not be any effect. Hope this was helpful. Best of luck. Dr. R ...Read more
