What test will rule out candida esophagitis or laryngeal candidiasis in an otherwise health non hiv positive person? what specialists do these tests?

An EGD, G.i. doctor: To get a 'good look' at the esophagus, a gastroenterologist (G.I.) doctor usually takes an 'endoscope' down the throat & esophagus for pictures and possible biopsy. You are sedated for the procedure (called an e.g.D.). The larynx is more accessible with a small scope through the nose, but this is done by an e.N.T. (ear-nose-throat). Hope this helps.

Inhaled steroids?: Healthy people don't get candidal esophagitis. They might if they use inhaled steroids, or have rare immune deficiencies. Oral antibiotics might increase risk for oral candidal infection (thrush); shouldn't affect larynx. Ent docs can evaluate larynx, throat: less invasive than endoscopy. Candidal esophagitis typically is painful, and may cause swallowing issues.
