Explain the differential diagnosis in this patient.
In your answer you should; highlight any abnormalities present in the patient's blood
test results, discuss them in relation to potential underlying causes (as suggested by
the test results and the patient's symptoms), explain how the normal analyte results
help with the differential diagnosis and suggest further tests that could be carried out
to confirm this diagnosis.
