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

Sonogram (Definition)

An ultraound, also known as a sonogram, is a painless and relatively inexpensive imaging test that utilizes sound waves instead of ionizing radiation. There are no side effects. Ultrasound can give us two-dimensional, and in some applications three-dimensional, images of structures and organs in virtually any part of the body. In addition to diagnostic uses, such as evaluating abnormalities in the abdomen, pelvis, and breast, ultrasounds are commonly used to guide needle and catheter placement in a variety of surgical ...Read more

What are the tests for vanishing twin syndrome?

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

How late can you detect a heartbeat from twin pregnancy with transvaginal ultra sound? If demise of one twin will other twin have issues?

How late can you detect a heartbeat from twin pregnancy with transvaginal ultra sound? If demise of one twin will other twin have issues?

Twin is high risk..: Generally, embryonic cardiac activity is seen between 5 and 6 menstrual weeks of pregnancy - single or twins or triplets. If both fetuses share a single placenta (monochorionic, monoamniotic placentation), and if one is demised, the other will likely have problems. A main concern is the effects of twin-twin transfusion. ...Read more

Pregnancy 15 week, ultrasound report.,.. Turner syndrome with cystic hygroma and hydrops fetalis....., your advise required?

Pregnancy 15 week,  ultrasound report.,.. Turner syndrome with cystic hygroma and hydrops fetalis....., your advise required?

Your decision: in the end. These findings in the first trimester usually carry a poor outlook for survival of the baby but there have been many reports of resolution of both cystic hygroma and hydrops as pregnancy progresses. Turner syndrome will always be there. I cannot decide for you but suggest you consider re-evaluating by ultrasound in 3-4 weeks should you decide to continue the pregnancy, you will then know more about the prognosis for the baby and any associated problems such as congenital heart defect etc. see:http://www.turnersyndrome.org/#!child/c4ff ...Read more

Is this normal pregnancy or miscarriage?
report details:
single intrauterine gestational sac seen measuring 2.2 cms,corresponding to 6+ weeks
no fetal

A little early: It sounds like your sonogram showed a very early pregnancy. Since no baby was seen there are two possibilities - too early to see or a miscarriage where the baby did not form. The sonogram will needed to be repeated in 1 -2 weeks to find out which is correct. ...Read more

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

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

Ultrasound result: single live intrautrerine pregnancy,presently cephalic,20weeks and 5days gestation,oligohydramnios fetal ascites..what can i do

See perinatologist: Its frightening to have an ultrasound that gives news that isn't perfect. Oligohydramnios means that there isn't enough fluid around the baby. You can help make more fluid by drinking lots and lots of water and getting enough rest. You need to see a perinatologist to find out why. This is a doctor who concentrates on complicated pregnancies to find out why. Best Wishes! ...Read more

Hcg betas 48 hrs apart: 1=51 2=60 3=130. Doc says either ectopic or viable pregnancy. Is there any chance this pregnancy will result in a live birth?

What is the progeste: Progesterone level, cause a prog under 10 is worrisome, under 5 is really bad and over 20 is great u need another beta and prog level to see if the beat doubles , if the beat keeps doubling then when it reaches about 2000 u should be able to see a sac( too early for ht beat in the uterus) but I am sure your OB has already explained all of this to u, if u have an sharp pain then u need immediate. ...Read more

Does noninvasive prenatal testing(cfDNA )capture baby's genetic defects?Is amniocentesis better for more accurate results? Im 31&12 weeks pregnant.

Does noninvasive prenatal testing(cfDNA )capture baby's genetic defects?Is amniocentesis better for more accurate results? Im 31&12 weeks pregnant.

Some and yes: The cf-DNA can detect many genetic anomalies but it is not 100% and when positive is usually confirmed by an amniocentesis for a full karyotype. The amniocentesis is the gold standard for detecting genetic anomalies . Sampling of the placental tissue _ ie: chorionic villus sampling would be comparable to an amniocentesis and can be performed earlier in the pregnancy. ...Read more

Anteverted,bulky gravid uterus,single intrauterine gestational sac 2.7 cm gestational age 6 weeks 6 days no fetal pole is this OK?or a miscarriage?

Blighted ovum: A gestational sac without a fetal with a gestational age of almost 7 weeks is most likely a blighted ovum (non development of the fetus). Most likely with result is a miscarriage. If not you may need a D&C. Follow up with your gynecologist in 1-2 weeks. ...Read more

Ultrasound at 6weeks 2days pregnant shows gestational sac, yolk sac, fetal pole n heartbeat (133bpm). What are the chances of miscarriage after this?

Ultrasound at 6weeks 2days pregnant shows gestational sac, yolk sac, fetal pole n heartbeat (133bpm).
What are the chances of miscarriage after this?

Risk is decreased: The fact the fetal pole has a heartbeat is very good and encouraging. However, the risk of miscarriage is still present until 12-13 weeks. That is why most celebrities do not release statements about pregnancy, due to the fact that miscarriage can happen. After this time, with a normal fetal heartbeat and placenta, the risk of miscarriage drastically decreases. ...Read more

Miscarriage?: There should be more than a yolk sac by now. There should be a fetus with a heart beat. It would appear that you have a missed abortion or what is normally called a miscarriage. This is unfortunate. Your infertility specialist that performed the ivf would be the best one to determine this. ...Read more
