Design outcomes
Primary
| Measure | Time frame |
|---|---|
| All results will be obtained at a single time point. Protein biomarkers: 1. Calprotectin measured using ELISA 2. EDN measured using ELISA 3. MUC2 measured using ELISA 4. MMP9 measured using ELISA 5. VEGF measured using ELISA 6. Soluble Cytokeratin 18 measured using ELISA 7. M2-PK measured using ELISA 8. Haemoglobin measured using ELISA 9. Measurement of additional protein biomarkers may be introduced at later stages of the project Nucleic acid markers: 1. Total DNA measured by spectrophotometry 2. Total DNA measured by real time PCR (beta-globin gene fragment amplification) 3. Measurement of additional DNA & RNA markers may be introduced at later stages of the project Cytology and immunocytochemistry: 1. Qualitative cytological examination of collected samples using microscopy 2. Immunocytochemical visualisation of protein biomarkers and qualitative assessment of their distribution using microscopy | — |
Secondary
| Measure | Time frame |
|---|---|
| Performance of each of the biomarkers/assays listed above as a diagnostic test comparing CRC presence versus CRC absence, measured by ROC (receiver operating characteristic) curve analysis (area under the curve, sensitivity, specificity) and calculation of test negative and positive predictive values as well as positive and negative likelihood ratios | — |
