Where can I send a criminal blood swab for DNA testing?

Yesterday, I came home from volunteering in a fundraiser to find that my padlock was destroyed to my front gate in the driveway, and my door completely, busted-wide open to my house with many of my electronics missing except my 27 in" television and computer. The intruder left blood smudged on the door, perhaps, from a mosquito bite since we have been receiving lots of rain this fall due to tropical storms. When the cop showed up to my house he filed a report from all things missing, and dusted finger prints from my entertainment center. I asked the cop if he was going to swab the blood stains from the door, and he said no. I was shocked!!! Then, I come to find out from another source that the state only pays for DNA testing when it's a murder scene. My question is if I swab it myself? Where can I send it to? Or can they send a professional to swab it? What if next time, it does turn out to be a murder? At least, I'll have that DNA sample in my records. This is the second time this year that they've broken into my home. The first time they cleaned me out completely, and I had to start from scratch. No doubt it's the same people. I know they're juveniles because they keep taking electronics, and it's more than one guy. Anyways, please help!!
