Use a UV light. The blood stain will appear black.
The best way to detect blood is with a very strong black light. Holding the light over a window frame will expose any bodily fluids, but it may not be possible to tell exactly what it is.
I found a link to this question, but don't seem to be able to pull up the actual question, so I don't know how old it is or the circumstances.

I have replaced my drivers rear slider window on two occations. you need to first find a window from a wrecking yard and then there are screws and bolts around the frame. Take these out and then gently pry around the frame where you will find some black soft tar-like stuff that weatherproofs the window. Keep prying gently. Be careful or you will break the new window. eventually the window will come away from the frame. You will need to purchase the black weatherstriping gook that comes as a roll. Clean the new window if it is used of all the old sealant with a razor blade or chisel gently. and put a caulking bead around the frame before installing it in the new frame. That is the best I can tell you.
