OncoMark Ltd is an Irish diagnostics company

Our primary focus is the development of novel panels of cancer biomarkers, to aid treatment decisions and personalise patient care. A biomarker is a biological measure that can be used to predict the course of a disease or to determine if a patient will respond to a specific treatment. 
Use of biomarkers in cancer can help doctors to personalise patient care by predicting whether or not they require certain treatments.
