What is noninvasive prenatal testing (nipt)?

What is noninvasive prenatal testing (nipt)?

Fetal DNA: Testing for free fetal DNA is available for detection of trisomies either from 9 weeks 0 days or 10 weeks 0 days, the latter being much less expensive. The results are available in 7 to10days with 99.99% accuracy. Both ACMG and FACOG recommend confirmation of an abnormal result with either amniocentesis or CVS. other non-invasive tests include fetal ultrasonography and prenatal screening. ...Read more

Can an EEG (electroencephalogram) detect brain tumors?

No: Eeg can show presence of seizure brain wave activity.These seizure brain activity can be caused by different conditions such as metabolic abnormality, lack of blood supply to brain cells, medication, epilepsy, brain tumor related, etc. It analyzes the brain "function" not the anatomy thus it can't detect brain tumor specifically. Mri needs to be done to detect brain tumors. Discuss with your md. ...Read more

Does an abnormal EEG confirm epilepsy in you?

Does an abnormal EEG confirm epilepsy in you?

Yes and no: The eeg is a tool to be used by a trained neurologist to help diagnose epilepsy. The eeg alone is of little value. The history and examination are the important elements. Eeg recorded during a seizure can be very helpful but difficult to obtain. Baseline eeg can show abnormal activity, especially in children, even though the patient has never had a seizure. It is valuable in the right hands. ...Read more

Would an EEG show MS? What about encephalopathy?

Not at all: EEG is not of value in confirming diagnosis of MS. If encephalopathy, abnormal EEG patterns may be present, but will not reveal etiology. Other tests needed to confirm either condition. ...Read more

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.

Exercise stress test, 24 hour holter monitor, echo doppler test--which is done first?

For what?: These tests provide different information and have different indications. Stress tests are to look for evidence to support a diagnosis of symptomatic blocked coronary arteries. Holtor is used to evaluate for dysthymia. Echocardiogram is useful to look at the heart valves and other features. Choosing the right test depends on what symptoms you are having. Discuss this with your doctor. ...Read more

Is jacob syndrome detectable through prenatal diagnostic tests?

Is jacob syndrome detectable through prenatal diagnostic tests?

Yes: Jacob's xyy is badly misunderstood. It makes a man taller, more at risk for acne, and he may speak later.

As an internet physician with an interest in xyy, i've saved the lives of over a dozen unborn children; many thank-you's and no one says they chose wrong. ...Read more
