If testing for dna on a gun and hat in a criminal cases how long before results would come back?

If this testing is done lets say for a city police department, and they have to send the evidence to the state crime lab for testing





Which is the commom procedure, since very few police departments have any crime labs.





Most testing will take about 3 to 4 months to be processed and results returned. They would rush high profile cases .





When we sent drugs to the state crime lab, we would do a field test, but it would take up to 6 months for the evidence to be process and the results returned to us.If testing for dna on a gun and hat in a criminal cases how long before results would come back?

2-3 weeks depending on the lab's case load.
