Is a hpt accurate 10 days after 2500 hcg shot 10 days ago?

  My Doctor's office was to put my pregnancy test results in my mailbox at there office this afternoon.  I have been crazy waiting all day long to see if I was pregnant.
  They did not give me my results!  I couldn't stand it anymore and purchased an Equate hpt.  The results were VERY POSITIVE.  
  I am concerned though that this may be from the HCG shot, as my doctor's office always requires a blood test.  What do you think?
Dear Kim:
hCG is slowly cleared from the body. Approximately one half of drug is removed each 28 hours. Thus, over 10 days, there are still several hundred units of hormone available be excreted into the urine and to give a false-positive home pregnancy test.
I caution patients that we need to be at least 12 and preferably 14 days from an hCG injection to be confident that a qualitative test is giving a reliable answer.
