Tauroselcholic [⁷⁵Se] Acid
Accurate diagnosis is essential for management of BAD disease
It is recognised that BAD is a chronic condition requiring long term therapy to achieve a significant improvement in diarrhoea symptoms, and therefore warrants a clear diagnosis;1 The results of the SeHCAT scan directly impact the choice of treatment for a person with BAD.2
SeHCAT results and response to therapy
- SeHCAT test has the benefit of being well-tolerated and non-invasive, and there is a clear inverse relationship between 7-day75 SeHCAT retention and response to bile acid sequestrants, which remain the first-line therapeutic option.3
- Studies have shown there is a relationship between the severity of the SeHCAT retention and the response to therapy.4
- Normal cut off ranges can vary between centres with some preferring to use 10% cut off, as patients with less than 10% bile acid retention are more likely to respond to BAS therapy.5
- However, it has been shown that 70% of patients with a retention of less than 15% will also respond to therapy.4
