What is nuchal translucency screening?

What is nuchal translucency screening?

Nuchal Translucency : Nuchal Translucency is a screening test to determine risk of chromosome abnormalities in a fetus. When the NT is greater than 3.5 mm, there is a 1 in 5 chance of a chromosome abnormality such as Turner or Down syndrome, or Trisomy 18. Additional tests should be ordered by an OB or genetic counselor for confirmation. A mother may decide to continue or end of the pregnancy based on the information. ...Read more

Screening (Definition)

Examples are: colonoscopy for colon polyp or cancer; mammograms for breast lesions or cancer; psa a blood test that could indicate enlargement of cancerous prostate tissue; blood sugar or hemoglobin a!c for diabetes. Many think that scanning the whole body will pick up a cancer--in all likelihood, it will not. There also is no good blood test, yet, ...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

Please interpret-
C.trachomatis RNA TMA Result: Detected. Standard range: Not detected. Test performed using the Aptima Combo2 (R) assay gen-probe(r)

You have chlamydia: "Detected" means the test found chlamydia -- i.e. a positive result. Return to the doctor or clinic where the test was done for treatment. (If you tested yourself at a lab, see a doctor or clinic ASAP.) Your current or recent sex partner(s) also need treatment. Good luck! ...Read more

Is transvaginal ultrasound accurate in detecting early pregnancy?

Is transvaginal ultrasound accurate in detecting early pregnancy?

Yes: At 5-6 weeks a gestational sac and pregnancy reaction can be seen. At about 7 weeks a tiny fetal pole and heartbeat can be seen. At less than 5 weeks, nothing may be seen so would need to check blood and urine results before planning for sono. ...Read more

Is the HIV DNA PCR test accurate enough for early diagnosis?

Is the HIV DNA PCR test accurate enough for early diagnosis?

Yes: The PCR is highly accurate and sensitive. It may take 6 weeks to 6 months for the elisa and western blot antibody tests to be positive. Since the PCR tests for the virus itself, it is detectable earlier, before an immune response has been initiated, but at a much higher price. ...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

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

Is the amnio test painless ?

Is the amnio test painless ?

No.: Mild cramping and significant emotional stress are typical aroudn/after amniocentesis. Most operators do not use local anesthesia as its administration would hurt more than the amniocentesis itself. Take some tylenol (acetaminophen) right before the procedure to numb the colicky cramps that follow. Risk of loss of pregnancy is between 1% and 1/1000 cases. ...Read more

How do they measure nuchal translucency?

Ultrasound: Nuchal translucency (nt) is typically measured between weeks 11 and 14. The sonographer measures the thickness of the tissues of the back of the fetal neck. After the image is magnified, calipers are placed along the inner margin of the tissues of the neck. ...Read more
