(Laegsgaard & Mors, 2008). The same researchers reported in 2009 that 37% of a mixed group psychiatric patients opposed psychiatric genetic prenatal testing (Laegsgaard et al., 2009). A 1993 U.S. study of bipolar patients and their spouses found that 44% would definitely or probably test a fetus; 39% of patients and 42% of spouses would definitely or probably not test a fetus; and 17% of patients and 15% of spouses were uncertain (Trippitelli et al., 1998). In the U.K., Jones and colleagues reported in 2002 that 29% of bipolar patients and 35% of general practice patients approve of prenatal testing for bipolar susceptibility genes (Jones et al., 2002). Meiser et al. (2008), working in Australia, found more support, reporting that 54% of bipolar
