age adjusted D-dimer cut-off values in older patients with suspected venous thromboembolism: systematic review and meta-analysis13 cohorts, 12497 patients, non-high PTPAge-adjusted cutoff = Age x 10Increases specificity by 10-20% (increasing
with age)Acceptable reduction of sensitivity to 97%PPV 21% (1 in 5)Reduction in up to 30-50% imaging!BMJ 2013;346:f2492
No standard reference 2 types of units
DDU = D-dimer unitsFEU = Fibrinogen Equivalent units
Local lab variation in conversion factorsMicrog/ml, nanog/ml, mg/L, etc.Will need system wide change
