These are the levels :-

3.0 to 8.0 nmol/l - re-sample in 2 days
9.0 to 15 nmol/l - mate in 2 to 3 days
15.0 to 30.0 nmol/l - mate in 24 to 48 hrs
>30.0 nmol/l - mate asap
>60.0 nmol/l -may be too late
The cost was around £28 when I used them earlier this year, then there's the cost of your vet drawing the blood sample and postage for first class next day delivery if you're not near enough to deliver the sample yourself.
I would have included the link tothe relevant section on the Idexx website but they seem to have changed it all and I couldn't find it.
