Methods for Detecting Oncofetal Fibronectin

A method for classifying the level of oncofetal fibronectin in a sample, comprising:

• measuring the amount of an oncofetal fibronectin protein in a sample taken from an patient at less than 25 weeks gestation;
• comparing the amount of oncofetal fibronectin protein in said sample to a threshold level of 200 ng/ml;
• and classifying the amount of oncofetal fibronectin protein in said sample according to said threshold level, whereby classification of oncofetal fibronectin protein molecule in the sample above said threshold identifies a higher risk of preterm delivery.
