Patent ID: 8506934

Claim:
A method of diagnosing hyposmia or anosmia in a human, the method comprising: (i) obtaining a nasal mucus specimen from the human; (ii) detecting a cyclic nucleotide level in said nasal mucus specimen; (iii) comparing said cyclic nucleotide level to a cyclic nucleotide level of a control population; and (iv) diagnosing said hyposmia or anosmia in the human based on a decreased level of said cyclic nucleotide for said nasal mucus specimen compared to the cyclic nucleotide level of the control population, wherein the cyclic nucleotide level is detected by an immunoassay, and wherein the method further comprises determining detection (DT) and recognition (RT) thresholds and magnitude estimation (ME) for four odorants: pyridine, nitrobenzene, thiophene and amyl acetate.
