Abstract:
One or more living entities are evaluated for health conditions by taking samples, especially samples of volatile compounds, derived from, e.g., the breath, urine, feces, saliva, skin exudates, etc., from the living entities, optionally with concentration of the samples; analyzing the samples using a multivariate analytical test; comparing the patterns present in the results of said test or tests, either; a. on an individual entity at a previous time to the patterns present in the results of said test or tests on the individual entity at the present time, or b/ comparing the patterns present in the results of the test on the said living entities to the patterns present in the results of tests on populations of similar entities having a normal health condition and/or to the patterns in the results of tests on populations of similar entities having a given disease or abnormal health condition, the results from the entities having normal health and each of the populations of entities having a given disease or abnormal condition being treated as reference sets for their respective specific disease or abnormal condition as compared to the reference set for entities having normal health.
