ABSTRACT
Accurate assessment of fetal lung maturity is essential in the management of high-risk obstetric patients. New rapid techniques have been developed to supplement time-consuming chromatographic methods. We compared one of these newer methods, the TDx-FLM, to the standard tests for fetal pulmonary maturity. There was an excellent correlation between the TDx and the lecithin-sphingomyelin ratio (r = 0.78). Although a TDx value of 70 or greater is considered mature, we found a value of 50 or greater predictive of fetal lung maturity in 100% of cases, and have chosen to redefine a mature value as 50 or greater in our institution. This value has greatly enhanced the clinical applicability of the test, allowing use of a large number of specimens from the previously poorly understood and often disregarded borderline category.
