Dr Dobie assesses patients who may be suffering from mould illness (biotoxin illness), and performs the tests for this illness recommended by Dr Ritchie Shoemaker. This illness arises when people are exposed to mould in a water-damaged building or a mouldy house. Toxins from mould can cause Chronic Inflammatory Response Syndrome (CIRS). Symptoms of CIRS can be similar to the symptoms of Lyme disease, and Lyme patients can sometimes also suffer from CIRS. Difficult cases of CIRS will be referred by Dr Dobie to a CIRS expert for treatment.
