Functions of genetic counseling include provision of risk information and provision of support in an effort to assist with decision making. This study examines (1) the relationship among intentions to test, self‐reported provision of blood sample, and receipt of test results; (2) the impact of genetic counseling on distress specific to gene status, perceived risk of developing breast and ovarian cancer in the context having BRCA1/2 mutations (mutations predisposing to increased risk of breast–ovarian cancer), and perceived risk factors for breast cancer; and (3) the clinical profile of those receiving/not receiving results. Intentions to test for BRCA1/2 mutations, self‐reported provision of blood sample immediately after counseling, and receipt of test results were statistically different but highly correlated, and intentions to test increased from pre‐ to postcounseling. A repeated measures ANOVA found distress specific to gene status and perceived risk factors decreased from pre‐ to postcounseling. Further, two clinical profiles of consultands emerged: (1) those receiving results with change in intentions to test having lower levels of distress and (2) those not receiving results and those receiving results with no change in intentions to test with higher levels of distress. Our findings are consistent with the function of genetic counseling—to provide information and support to those with familial cancer, as well as to assist in decision making. The provision of support is important as distress specific to gene status may impede flexible decision making about genetic testing.
