How come the source of septicemia can't be found?

The reason why I ask is because four years ago my mom died of septicemia. She came home one day and was walking like she pulled or pinched a nerve. Towards the end of the week, it was her neck that was sore and everyone told her that it was sore because she was 'babying' her leg. My dad and i took her to the e.r. and they gave her an morphine injection without doing any labs. what it was is that she had a blood infection. they said that she had it for a long time and didn't know about it. it was too late for her. she was on four or five different antibiotics and none were working. the reason why i ask the question, is because one of her doctors said that sometimes the source of infection can be so small that it can't be picked up on tests. we ended up having to take her off of life support. i don't understand. i would like to know.

Septicemia is a systemic disease caused by the presence of pathogenic microorganisms and their toxic products in the blood.
I think with a throughly blood test in a good lab this disease will be known.

I lost my father on Apr 05 to Septicemia I beleive ER staff should test first before guessing and sending patience home//As was in my father case Report It

This might sound really strange- but a friend of mine almost died with septicemia- they wound up flying him out to another hospital- they found the cause of his septicemia to be from an abcess in his mouth- once they started treating that he came out of it. A mouth abcess- I think it was under a tooth- who would have guessed? It not what doctors usually look for. Hope that helps- D

hi there, the source of septicemia can be found, it is blood poisoning caused by infection like burst appendix, meningitis, and abcesses, the doctors will do tests to find out where the infection is once they find out they will give treatment for both the infection and the septicemia.
my sister in law came close to death, and all because of a contraception injection, her leg started to swell and the doctor told her to rest and take pain killers, but when she got worse and collapsed, her husband got her to hospital where he was told she would have died if he hadn't have taken her when he did, the doctors did the tests and therefore found the source was infact from the injection, silly really, but it goes to show the simplest of things can be life threatening.
i hope this helps

septicemia is not localized which means other organs of the body are already infected of the so-called disease so the person need to undergo laboratory examination to help for its diagnosis.
