Stress Test is 0.04%.11This modality, however, is limited by its false-positive rate of up to 30%, and by the various contraindications, such as prematurity andplacentapraevia. In most centres it has gradually been replaced by the Non-stress Test and the cardiotocograph, which evaluates...
Related to nonstress test:Biophysical profile,Contraction stress test non·stress test (nŏn′strĕs′) n. An ultrasound examination of a fetus that measures fetal well-being by correlating fetal movement with changes in fetal heartbeat. ...
The nonstress test is commonly used as a test of fetal well-being, despite the fact that both false-positive and false-negative results are known to occur. Although some of the errors are due to biologic variability among fetuses, some may be due to variability of reading the test. The ...
Rh incompatibility:If your blood is Rh negative and your baby’s is Rh positive and this isn’t your first pregnancy, the doctors may want to monitor the baby using a nonstress test. Low amniotic fluid:Ifamniotic fluidis low (known as oligohydramnios), a nonstress test can be used to ...
To determine whether maternal glucose administration can decrease the incidence of false positive nonstress tests, 296 nonstress tests were performed on 235 high-risk obstetric patients in a prospective controlled study. Patients were alternately given a 50 gm oral glucose drink or an equal volume of...
CONCLUSIONS: The nonreactive test could identify a population at risk but it was not helpful as a 'stand alone' modality in decision making, because of the low sensitivity and positive predictive value rates (40.9% and 28.1%, respectively)....

However, the hypothesis that stress is related to higher grade point averages (GPAs) among persisters and lower GPAs among nonpersisters was not strongly supported. Stress had a negative effect on GPA among persisters, but there was some evidence of a positive indirect effect through active ...
Based on that, these peaks were categorized as the true positive (TP), false positive (FP), or false negative (FN). The TP peaks are the R-peaks in the extracted signal, which lie within ± 50 ms interval from the reference annotations. Detected R-peaks in the extracted signal, which...
magnetic field (hatched) region where the spin-collinear ferromagnetic state is stable, the difference Δvp of the peak frequency of L12 and L21 (representing the magnon energy difference propagating from terminal 1-to-2 and 2-to-1) is opposite in sign in the positive and negative magnetic ...
