Hepatitis and blood. The red cross disqualifies anyone who has had any hepatitis (a, b, c, d or e) or jaundice after the age of 11. Exceptions include non-viral causes of hepatitis or jaundice such as gilbert's disease. Presumably the reason is to cast a wide net over all cases of viral hepatitis to ensure not missing a case of non-a hepatitis.
