|
|
Meconium presence
|
Absent except in breech presentation (anoxia).
Presence indicates fetal hypotension or distress. |
|
Creatinine values
|
More than 2 mg/100ml in a mature fetus.
Decrease may indicate immature fetus - less than 37 weeks. |
|
L/S ratio

Most common test used for maturity. Should be more than 2.
ex. 2/1=2=probably maturity. 3/1=3=almost absolute maturity. decrease undicates pulmonary immaturity and subsequent respiratory distress syndrome. |
