More evidence for the CerviLenz device!

Two new independent studies conclude that the CerviLenz device is an effective first line tool to screen for patients who do not require further evaluation with TVU.

In a study of 99 patients, a CerviLenz measurement < 25 mm predicted a TVU cervical length < 25 mm (89% sensitivity, 90% specificity, 95% negative predictive value, 77% positive predictive value). Click here to see all the data, presented as a poster at the SMFM 2013 Annual Meeting.

In a different study comparing 253 CerviLenz measurements to 259 TVU cervical length measurements, a CerviLenz measurement < 24 mm predicted a TVU cervical length < 25 mm (84% sensitivity, 73% specificity, 98% negative predictive value, 25% positive predictive value).
