| | Blood transfusion and CJD (Site not responding. Last check: 2007-10-13) |
 | | Meantime it was clear that infectivity was present in the blood of scrapie cases in various species (mice, hamsters etc) and in 2003 it was shown that if sheep were bled, before they were symptomatic with scrapie, then their blood would transfer the disease to other sheep by transfusion. |
 | | As such it would be expected that 300ml of the blood of a person incubating CJD would be able to transfer the disease by blood transfusion and because of this CJD patients, relatives and persons having received human growth hormone are banned in the UK from donating blood. |
 | | An attempt was made to compare the proportion of people with CJD that have received a blood transfusion with the proportion of controls and no statistical difference was found (n = 200) (235), however the difference by calculation was expected to be 2 and this could not be shown unless the survey was greater. |
