Hi , My female dog was progesterone tested on day 9 of her season and the result has come back as 8 nmol/l , so how many days till she can be mated ? she shall have 2 matings .
Thanks

I would say she needs retesting in a couple of days.  Didn't the person tell you, they do at Idexx?

there is a scale on here somewhere,

be careful as some are n/mols and some are n/gms , both have very different meanings/results...!

i had mine done with fit&fertile and they are n/gms  ( n meaning nano :-) )

have posted this chart many times before ::

0-2  nmol/L           Baseline concentrations too early to estimate ovulation 
3 - 6 nmol /L        Minimum 2 days before ovulation expected however result of 3 - 4 nmol/L may persist for a week or longer before increasing. Earliiest estimating breeding 4 - 6 days but could be longer (re test needed)
7 - 12 nmol/L   Minimum 1 day before ovulation. Estimated window for breeding 3 - 5 days but could be longer  ( re test recommended) 
13 - 18 nmol/L   Ovulation impending or just occurred. Estimated breeding window 2 - 4 days  
19 - 31 nmol/L   Ovulation recently occurred. Estimated breeding window 1 - 3 days
32 - 64 nmol/L   Ova have matured, optimal potential for fertility.  Estimated breeding window  0 - 2 days
65 - 90 nmol/L   Ova have matured but aging, decreased potential for fertility.  Breed  at once
Above 90 nmol/L    Too late

NB == IF result are given to you in Ng/l x 3.18 to give reading in nmol/l and use chart as above

good luck :)

So a retest is needed really.

Thank you for replies , I am taking her to have another progesterone test on wednesday .
