had my bitches blood taken on the 29/12/2010 still no result back
how long does it useuly take

Had my boys blood test taken 6/12 and only got phoned with result last week.

Mine usually take about 3 weeks but with New Year I guess things may be a bit slower.  As long as you have a positive titre you will be able to count 6mths from date of blood draw and NOT date of returned result for your passport.

Draco's only can back last week and his was taken well before your bitches was taken, don't worry too much its been the holiday season
