depends on how much and how long.... there may be a trace of it in your blood.... but you should be honest with your doctor... remember they are bound by laws to keep that information confidential. Your doctor needs to trust you too..so you should be honest.

it depends how much blood you have, if there's a lot, then it will appear a brick red color, but if its not so much, then it looks bright red untill it dries, then its brick red once again

Trace residue from gunpowder can be found even after thoughly washing your hands or other parts of your body. When firing a gun the resiude in not only depositied on hands but over a large area.  The length of time in which the residue can be detected is variable, depending on many factors and the testing method used. Providing details of residue detection would not be a good idea, so I'll leave it a that.

I think the concentrations would be too small to be visible.  you would only be able to react with the available OH-'s, which is 10^-7 mol/L, in theory the maximum quantity of Pb(OH)2 you could make then would be 5x10^-8 mol/L.  If Le Chatelier's principle came into play maybe a little more, but that's assuming everything reacted, which probably wont happen.

It slowly gets absorbed into the blood and tissues around. Depending on the amount, it should be gone in a few days to a week or so.

no.\n\nyou need direct contact with blood, or bodily fluids. (and spit does not count unless you are drinkning it in buckets)

Normal red blood cells have a life of about 120 days, and do not have a nucleus, so DNA is extremely minimal. White blood cells, which do have a nucleus, last about 10 days. Transfused blood has had most of the white cells taken out, and does not last as long as your own blood when transfused. So the amount of time it would take for the donor DNA to be cleared from the body would be days, not years. I believe that a swab from the inside of the mouth would circumvent any problems involving blood transfusion and DNA, anyway.

I am ashamed to say I do not think of it so deeply, but you bring up wonderful points.  It surely is an amazing thing, the human body and the way it works.  I love not only the question but you left us with specifics so we did not just have to uhm blood good... I now have a little more knowledge to add to my trivial pursuit portfolio!!  hehehehe

Simple, bad blood goes from the heart to the lungs thru the pulmonary veins, and return to the heart already oxygenated thru the pulmonary arteries..☺

bodily fluids (semen, blood etc)

Not necessarily. A lot of people assume the blood and guts and all other types of stuff will ooze out and junk like that but in reality this is not so. Usually the blood is already drained out, and the inside is actually clean, (although smelly) to allow you to clearly see all of the parts and so forth. It can be quite interesting actually.

just a guess but i'd say the blood was not from being struck and restrained i would suggest the cocaine presumably inhailed through the nose caused a failure /rupture of the sinus cavity  Similar to overdose and the man was oding before he was beaten and restrained it just took 20 mins or so for the od to fully kick in the cocaine may not have fully absorbed into the bloodstream by the time he was tested / after the sinus was already destroyed preventing more from showing up in the bloodwork.  but that's just an uneducated guess.

Dont take the item out of the body, it will cause internal bleeding and possibly cause more damage than needed..
