My DH died on 26 June,his body was due to be released for burial today, but was retained for histology tests as PM had not shown cause of death. I was very shocked as all verbal evidence from onlookers (he died suddenly away from home) was consistent with a massive heart attack which I am told would normally be seen on the heart at PM. I realise this may raise emotions for people, the same ones I am reeling from myself but I would be so grateful if anyone could tell me what these tests might be looking for.
