Your grandmother having chronic cough... In tuberculosis along with cough weight loss, anorexia and low grade evening fever can be present ... For TB confirmation following investigation can be done ...chest x-ray sputum examination for AFB stain if needed culture TB PCR or NAT like genetic testing ...
