    The sensitivity and specificity of these tests, however, for most have not yet been validated. [11] The Natera SMART study however has shown that most cases of 22q11.2 deletion can be detected using SNP based NIPT/NIPS (Panorama) including smaller nested deletions whilst still maintaining a low false positive rate.

  3. Prenatal testing - Wikipedia

    en.wikipedia.org/wiki/Prenatal_testing

    One of the major advantages of the non-invasive prenatal testing is that the chance of a false positive result is very low. This accuracy is very important for the pregnant woman, as due to a high sensitivity and specificity of the testing, especially for Down syndrome, the invasive testing could be avoided, which includes the risk of a ...

  4. Sensitivity and specificity - Wikipedia

    en.wikipedia.org/wiki/Sensitivity_and_specificity

    Sensitivity and specificity values alone may be highly misleading. The 'worst-case' sensitivity or specificity must be calculated in order to avoid reliance on experiments with few results. For example, a particular test may easily show 100% sensitivity if tested against the gold standard four times, but a single additional test against the ...

    (MPSS) is estimated to have a sensitivity of between 96 and 100%, and a specificity between 94 and 100% for detecting Down syndrome. It can be performed at 10 weeks of gestational age . [ 66 ] One study in the United States estimated a false positive rate of 0.3% and a positive predictive value of 80% when using cffDNA to detect Down syndrome.

    The most common abnormality the test can screen is trisomy 21 (Down syndrome).In addition to Down syndrome, the triple and quadruple screens assess risk for fetal trisomy 18 also known as Edwards syndrome, open neural tube defects, and may also detect an increased risk of Turner syndrome, triploidy, trisomy 16 mosaicism, fetal death, Smith–Lemli–Opitz syndrome, and steroid sulfatase ...

  9. Diagnostic odds ratio - Wikipedia

    en.wikipedia.org/wiki/Diagnostic_odds_ratio

    The log diagnostic odds ratio can also be used to study the trade-off between sensitivity and specificity [5] [6] by expressing the log diagnostic odds ratio in terms of the logit of the true positive rate (sensitivity) and false positive rate (1 − specificity), and by additionally constructing a measure, :
