**7.8. Proteomic technology**

This enables analysis of cluster patterns produced based on the size and net electrical charge of serum proteins produced by the various tumours. The proteome represents all the possible gene products of the cell and the proteomic technology characterizes all protein in biological system including the complex features. This method increased the sensitivity and specificity by 100 and 95% respectively with a 94% positive predictive valve for ovarian tumours (Angela et al 2013).
