Western blots of individual whole sera from women undergoing surgical management of EP, surgical management of NVIUP and surgical termination of VIUP were probed with antibodies specific for: HBB; ADIPO; FN1; and PSG4.

Integrated density values of specifically labelled bands were normalised against a positive control (pooled VIUP serum). ROC curves were generated for ectopic vs non-ectopic patient groups.
