Antepartum Testing (Overview)

Your health care provider should closely check both you and your baby throughout the pregnancy. Fetal monitoring to check the size and health of the fetus often includes ultrasound and nonstress tests. * A nonstress test is a very simple, painless test for you and your baby. A machine that hears and displays your baby's heartbeat (electronic fetal monitor) is placed on your abdomen. When the baby moves, the baby's heart rate normally increases 15 - 20 beats above its regular rate. * Your health care provider can compare the pattern of your baby's heartbeat to movements and find out whether the baby is doing well. The health care provider will look for increases in the baby's normal heart rate occurring within a certain period of time.

Do ovum donors undergo genetic testing or pedigree evaluation?

Yes: Check with your rei specialist for details, but all ovum donors would be asked to report a detailed family history and would be tested for common recessive disorders, such as cystic fibroisis. Many programs would also request more extensive testing including a panel of 100 such recessive diseases, including such problems as spinal muscular atrophy, the askenazi jewish panel, fragile x, & more. ...Read more

What are amniocentesis, chorionic villus sampling and blood/saliva test screening used for? Abortions?

Prenatal diagnosis: Cvs and amniocentesis are used to discover chromosomal abnormalities in the fetus. They are also used to diagnose genetic diseases, such as cystic fibrosis, that some people are at risk for. Blood and saliva screening tests are used to find out if parents are at risk for a baby with certain genetic diseases. ...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

What is non-invasive prenatal paternity testing?

What is non-invasive prenatal paternity testing?

NIPP: Non invasive paternity testing is a technology based on detection of fetal cells in the mother's blood. A variety of specialty labs offer this service and cite the ability to find such results as early as 8 weeks into the pregnancy. Traditional testing requires fetal cells from invasive procedures like sampling amniotic fluid by needle or the placental cells. ...Read more

got negative HEP C RNA test (lower limit 15 IU/mL) Oct 16 after year inconclusive antibody results. Treatment, further testing or follow up needed?

got negative HEP C RNA test (lower limit 15 IU/mL) Oct 16 after year inconclusive antibody results. Treatment, further testing or follow up needed?

Hep C negative: This is an extremely good (sensitive) test for the presence of Hepatitis C. Since the test is negative, that means you don't have it. It's possible you HAD it- but your body took care of it and wiped it out. Since your antibody test is weakly positive-this probably happened some time ago, or it could be a false (weakly) positive test that's cross reacting with something else. Would still see MD... ...Read more

Fetal medicine docs. With a negative verify and sequnom result for downs test would u still recommend amnio for 1in20 risk from routine screen blood?

Fetal medicine docs. With a negative verify and sequnom result for downs test would u still recommend amnio for 1in20 risk from routine screen blood?

NO.: Maternit21 is much more accurate than the ultrasound-dependent serum analyte screening. If the former is reassuring for your risk to have a baby with down syndrome then the latter is irrelevant. Disregard the serum screening and decide about amniocentesis on the basis of the cell free fetal dna analysis. Most couples accept a <1% risk of down syndrome without amniocentesis. Best of luck. ...Read more

Pcr blood test for hsv1 & hsv2 both negative 7 weeks post exposure. Is this a reliable test vs igg antibody testing?

HSV testing: Both are good. A PCR blood test looks for circulating viral DNA. The IgG look for the development of an antibody against the virus. If these are not present 7 weeks after exposure then the most likely conclusion is that you did not acquire it. ...Read more

Safety of chorionic sampling vs. Amniocentesis for prenatal diagnosis of chromosomal abnormalities?

Risks: The risk of pregnancy loss has been looked at in four randomized studies of cvs vs. Amniocentesis. All four studies show that both procedures have about the same risk of pregnancy loss. About 1 in 1600. Another cvs study showed that losses in a group of women who had the procedure were equal to losses in a group of women who didn't have the procedure. A loss may not be related to the procedure. ...Read more

Why would a pregnant person   need chorionic villus sampling (cvs)?

While most, if not all, of these defects are not curable, it does give the patient the earliest opportunity to decide on whether to continue the pregnancy. ...Read more

Why my blood count drops so quickly during pregnancy while my ferritin is >UNL? I'm at high risk for antepartum/postpartum hemorrhage (had IV iron due to the bleeding risk and IDA diagnosis prior to preg). Why do I still have anemia without iron/b12/folat

Why my blood count drops so quickly during pregnancy while my ferritin is >UNL? I'm at high risk for antepartum/postpartum hemorrhage (had IV iron due to the bleeding risk and IDA diagnosis prior to preg). Why do I still have anemia without iron/b12/folat

Inflammation?: I would think about this being secondary to anemia of chronic disease. Ferritin can be an acute phase reactant, essentially being indicative of ongoing inflammation; inflammation that can act as a mechanism for speeding up loss of red blood cells...Also look into your MCV. High MCV I would look into thyroid dysfunction. Pregnancy hemorrhage --> Panhypopituitarism --> Low thyroid --> Macrocytosis ...Read more

Can u get DNA of child before birth?

Possible: Dna tests are preformed on cellular material. To get a babies dna prior to birth & be sure its not a contaminant from the mother, you have to get it through chorionic villus sampling or amniocentesis. Both are occasionally done for specific medical problems including genetic diagnosis for chromosome defects, metabolic disorders. The risks of death & infection to mom & baby preclude random testing. ...Read more

On rare occasions, if mom has medical conditions that produce certain hormones, it can affect the way a baby girl's genitalia look to make them look somewhat male, but she is still genetically a female. More likely if they said you were having one sex or the other, they made a mistake when looking at your ultrasound. ...Read more
