Abstract
A test kit and method of determining fetal pulmonary maturity which method comprises visually comparing a test amniotic fluid with selected positive and negative control samples and which test kit includes selected positive and negative control samples for comparison purposes.

A method for the determination of fetal pulmonary maturity from an amniotic fluid test sample, which method comprises:
- visually comparing a pigment-free amniotic fluid test sample from a patient to a positive control sample which mimics an optical density (OD) of about 0.80 at 650 nm which indicates fetal pulmonary maturity and a negative control sample which mimics an optical density (OD) of about 0.50 at 650 nm which indicates fetal pulmonary immaturity and from said comparing providing an indication of the fetal pulmonary status of the fetus.
A test kit for the determination of fetal pulmonary maturity from an amniotic fluid test sample, which test kit comprises in combination:
- (a) a positive control sample constructed so as to mimic an optical density (OD) of about 0.80 at 650 nm which indicates fetal pulmonary maturity;
- and
- (b) a negative control sample constructed so as to mimic an optical density (OD) of about 0.50 at 650 nm which indicates fetal pulmonary immaturity
- whereby visually comparing the test sample with the positive and negative control samples provides an indication of fetal pulmonary maturity of a fetus.
