Since the patient is believed to be at 35 weeks gestation, performing an L/S ratio may not provide accurate results as the predictive value of the test decreases as gestational age increases. Therefore, an Amniostat test should be performed as it directly measures the level of bilirubin in the amniotic fluid to assess fetal lung maturity and determine the need for delivery. Additionally, the fact that the patient is diabetic increases the risk of preterm delivery and fetal respiratory distress syndrome, making the Amniostat test a more appropriate choice in this case.
