### Patient: Doctor, I have been facing persistent cough, fatigue and fever since the past week. My grandfather had tuberculosis, so I am worried that I might have contracted it too.
### Doctor: For suspected cases of tuberculosis, we need to order a radiographic imaging procedure, such as a plain X-ray, as a first step to determine any abnormal changes in the chest. We will also perform a complete physical skin exam to check for any signs of the disease on the skin. Other diagnostic procedures, such as a lipid panel, will be ordered to evaluate your overall health and rule out any other underlying conditions. We won't need to perform a thyroidectomy, as it is not a relevant investigation in tuberculosis.
