Device and method for assessing asthma and other diseases

A method for assessing asthma in a subject, comprising:

• providing a device comprising a mouthpiece apparatus, a condensation apparatus and a collection apparatus;
• receiving a subject's breath in said mouthpiece apparatus;
• condensing said breath in said condensation apparatus to form a condensate;
• collecting said condensate in said collection apparatus;
• testing said condensate within said collection apparatus to determine acetic acid or acetate concentration or both said acetic acid and acetate concentrations;
• and
• evaluating said acetic acid or acetate concentration or both said acetic acid and acetate concentrations to determine the presence, absence or status of asthma in the subject.

A device for assessing a disease in a subject, said device comprising:

• a mouthpiece apparatus configured to receive breath from a subject;
• a condensation apparatus configured for operative connection to said mouthpiece apparatus, and being further configured to condense the subject's breath and produce a condensate having acetic acid or acetate or both said acetic acid and acetate;
• and
• a collection apparatus configured for operative connection to said condensation apparatus, said collection apparatus comprising a collection chamber containing means for testing said condensate to determine said acetic acid or acetate concentration or both said acetic acid and acetate concentrations, wherein the subject's breath may be received, condensed and evaluated in a single device to determine the presence, absence or status of a disease in the subject.

A device for assessing a disease in a subject, said device comprising:

• a mouthpiece apparatus configured to receive breath from a subject;
• a condensation apparatus configured for operative connection to said mouthpiece apparatus, and being further configured to condense and collect the subject breath and produce a condensate having acetic acid or acetate concentration or both said acetic acid and acetate concentrations;
• and
• said condensation apparatus comprising a means for testing said condensate to determine said acetic acid or acetate concentration or both said acetic acid and acetate concentrations.

A method for assessing a disease in a subject, said method comprising:

• said subject exhaling through a measuring device or substance, said measuring device or substance effective for detecting acetic acid or acetate or both acetic acid and acetate;
• testing said detected acetic acid or acetate or both said detected acetic acid and acetate to determine said acetic acid or acetate concentration or both said acetic acid or acetate concentrations;
• and
• evaluating said acetic acid or acetate concentration or both said acetic acid and acetate concentrations to determine the presence, absence or status of a disease in the subject.

A device for assessing a disease in a subject, said device comprising:

• a mouthpiece apparatus configured to receive breath from a subject;
• a measuring device or substance configured for operative connection to said mouthpiece apparatus, said measuring device or substance effective for detecting acetic acid or acetate concentration or both said acetic acid and acetate concentrations from said subject's breath;
• a means for testing said trapped acetic acid and acetate to determine said acetic acid or acetate concentration or both said acetic acid and acetate concentrations;
• and
• an evaluating means for evaluating said acetic acid or acetate concentration or both said acetic acid and acetate concentrations to determine the presence, absence or status of a disease in the subject.
