OBJECTIVE: We evaluated the usefulness of the recently introduced TDx FLM assay in determining fetal lung maturity. STUDY DESIGN: The TDx FLM assay was compared with the lecithin/sphingomyelin ratio, the foam stability index, and the presence of phosphatidylglycerol in amniotic fluid samples from 102 pregnancies,

2002年5月1日 · Our objective was to determine the optimal diagnostic cutoff value for the TDx-FLM II assay (Abbott Laboratories) for predicting clinically significant RDS. Methods: Amniotic fluid TDx-FLM II data were collected retrospectively over 4 years. Women were included in the study if they had delivered within 72 h of TDx-FLM II testing and both the ...

1993年3月1日 · The recently introduced TDx FLM assay (Abbott Laboratories, Abbott Park, 111.) is an automated fetal lung maturity test that is based on fluorescence polar­ization. With a simple procedure and instrumentation available in virtually all laboratories, this test can be performed in less than an hour, with intralaboratory and interlaboratory ...

excellent tool in determining fetal lung maturity as none of the neonates had RDS develop when the FLM test was 55 mg/g or more. This study supports the findings of Ste-infeld et al1 and Herbert et al2 who, evaluating the origi-nal TDx-FLM assay with a cutoff value of 70 mg/g to indicate maturity, suggested that lower cutoff values were

Objective: We evaluated the usefulness of the recently introduced TDx FLM assay in determining fetal lung maturity. Study design: The TDx FLM assay was compared with the lecithin/sphingomyelin ratio, the foam stability index, and the presence of phosphatidylglycerol in amniotic fluid samples from 102 pregnancies, among which respiratory ...

The purpose of this study was to evaluate the usefulness of the TDx/TDxFLx FLM II assay (Abbott Laboratories), a newer version of the TDx-FLM, in the initial evaluation of fetal lung maturity. The assay is different from the earlier version in the packaging of the reagents, the sample volume required is 0.25 mL instead of 0.5 mL, and the value ...

A satisfactory amniotic fluid specimen is essential for accurate assessment of fetal lung maturity. The FLM is much more precise than the L/S ratio at the medical decision point and is perhaps, the best single assessment of fetal lung maturity.

Objective: We evaluated the usefulness of the TDx-FLM II and lecithin to sphingomyelin (L/S) ratio assays in predicting fetal lung maturity. Study design: We retrospectively reviewed 218 consecutive paired TDx-FLM II and L/S ratio results. Women who delivered viable infants within 72 hours of amniotic fluid collection (n=109) were included in ...

Study patients consisted of insulin-dependent diabetic women who had undergone transabdominal amniocentesis with assay of the fluid by the TDx-FLM method. Pertinent data were requested concerning pregnancy and respiratory outcomes of the corresponding neonates. Results: Data from 261 pregnancies at 13 institutions were collected.

2002年5月1日 · Uncontaminated amniotic fluid obtained by transabdominal amniocentesis for fetal lung maturity assessment was evaluated using the fetal lung maturity cascade and the TDx FLM. The TDx FLM...
