Qualitative urine pregnancy tests vary in sensitivity. High-sensitivity tests are more common and typically detect hCG levels between 20 and 50 milli-international units/mL (mIU/mL). Low-sensitivity tests detect hCG levels between 1500 and 2000 mIU/mL and have unique clinical applications, including confirmation of medication abortion success. [12]
In fact, consider that Down syndrome affects about 1:400 pregnancies; if you screened 4000 pregnancies with a Quad test, there would probably be 10 Down syndrome pregnancies of which the Quad test, with its 80% sensitivity, would call 8 of them high-risk. The quad test would also tell 5% (~200) of the 3990 normal women that they are high-risk.
Fetal fibronectin testing has poor specificity (64%) and positive predictive value (10%). [5] Because of this, the American College of Obstetricians and Gynecologists does not consider positive fFN as diagnostic of prelabor rupture of membranes in the absence of other signs and symptoms and cautions that "[t]hese test kits should be considered ...
In medical diagnosis, test sensitivity is the ability of a test to correctly identify those with the disease (true positive rate), whereas test specificity is the ability of the test to correctly identify those without the disease (true negative rate). If 100 patients known to have a disease were tested, and 43 test positive, then the test has ...
Pregnancy detection can be accomplished using one or more various pregnancy tests, [75] which detect hormones generated by the newly formed placenta, serving as biomarkers of pregnancy. [76] Blood and urine tests can detect pregnancy by 11 and 14 days, respectively, after fertilization. [77] [78] Blood pregnancy tests are more sensitive than ...
The triple test, also called triple screen, the Kettering test or the Bart's test, is an investigation performed during pregnancy in the second trimester to classify a patient as either high-risk or low-risk for chromosomal abnormalities (and neural tube defects). The term "multiple-marker screening test" is sometimes used instead.
