All diagnostic laboratories in New Zealand are standardising to the same reporting units for D-Dimer.  We will change our D-Dimer reporting units from mg/L to ug/L FEU (fibrinogen-equivalent units) (e.g. 0.5 mg/L to 500 ug/L FEU). 

The new cut-offs will be:

Age (years old)	Cut-off (ug/L FEU)
≤ 50	500
≤ 60	600
≤ 70	700
≤ 80	800
≤ 90	900
>91	1000
