12. Genetic Testing: In cases of suspected genetic factors, genetic tests may be ordered.
13. Psychological Evaluation: Assessments for depression and anxiety may be included.
14. Nutritional Assessment: Blood tests can check for nutritional deficiencies.
15. Sinus Imaging: X-rays or CT scans can identify sinus issues.
16. Olfactory Event-Related Potentials (OERPs): An advanced test to measure olfactory processing in the brain.
17. Biopsies: In some cases, a biopsy of the olfactory tissue may be needed.
18. Intranasal Injections: Specialized tests can involve the application of specific substances to the olfactory region.
