  1. I agree.. For misdemeanors it is kept for at least one year. Felonies, they will keep longer.


  2. Labs must keep it for atleast 1 year. However, there may be other issues, such as: enough blood drawn to be retested; preservative levels being sufficient to prevent fermentation, etc.

    Any information provided through Avvo.com in response to a question is not, and cannot be considered a formation of any Attorney-Client relationship. Questioner understands that the nature of this system allows only for a cursory review of case information, and more detailed information should not be divulged in this public forum. As such, Questioner is recommended to contact an Attorney in order to discuss the full details of their case and a more specific advisement of potential rights and liabilities.


  3. For a misdemeanor offense it is mandatory that the sample be kept for one year. You will need to file a motion for chain of custody to have the sample retested, often colloquially referred to as a 'Blood Split' motion. You should certainly be speaking with a qualified criminal defense attorney in your local.
