Batch-analyse Fase 2: supar udvikles til KBAs analyseplatform (Cobas

7 Fase 1: supar analysen etableres på analyserobot (BEP2000) som en ELISA metode. Batch-analyse Fase 2: supar udvikles til KBAs analyseplatform (Cobas 6000) som en particle-enhanced immunoturbidimetrisk metode. Løbende analyse døgnet rundt med svar indenfor 3 timer efter prøvetagning.

22 Cardiovascular risk prediction in the general population with use of supar, CRP and Framingham Risk Score S Lyngbæk, J Marott, T Sehestedt,T Hansen, MH. Olsen, O Andersen, A Linneberg, SB. Haugaard J Eugen-Olsen, P Hansen, J Jeppesen The inflammatory biomarkers soluble urokinase plasminogen activator receptor (supar) and C-reactive protein (CRP) independently predict cardiovascular disease (CVD). The prognostic implications of supar and CRP combined with Framingham Risk Score (FRS) have not been determined. From 1993 to 1994, baseline levels of supar and CRP were obtained from 2315 generally healthy Danish individuals (mean age: 53.9 years) who were followed for the composite outcome of ischemic heart disease, stroke and CVD mortality. Results During a median follow-up of 12.7 years, 302 events were recorded. After adjusting for FRS, women with supar levels in the highest tertile had a 1.74-fold and men a 2.09-fold increase in risk compared to the lowest tertile. Including supar and CRP together resulted in stronger risk prediction with a 3.30-fold increase for women and a 3.53-fold increase for men when both biomarkers were in the highest compared to the lowest tertile. The combined extreme tertiles of supar and CRP reallocated individuals predicted to an intermediate 10-year risk of CVD of 10 20% based on FRS, to low (< 10%) or high (> 20%) risk categories, respectively. Conclusions supar provides prognostic information of CVD risk beyond FRS and improves risk prediction substantially when combined with CRP. Journal of Cardiology 2013

23 Low supar

24 High supar

25 Is triaging now supar easy? supar is not a miracle. Clinical assessment is Number 1. In most cases, supar will add no further value. In some cases, a high or low supar value may aid in deciding -whether to examine the patient further -whether to hospitalize a patient or not.
