The Histoplasma antigen enzyme immunoassay (EIA) is a noninvasive test used for determining disease remission and detecting disease relapse in humans with histoplasmosis.

At the time of diagnosis, antigen was detectable in urine in 14\/15 (93%) cats and in serum in 11\/15 (73%) cats. Both serum (P &amp;lt; .0005) and urine (P &amp;lt; .0001) antigen concentrations significantly decreased over time with effective treatment. Antigen elimination was sensitive [urine, 90.0% (95% CI 72.3\u201397.4%); serum, 90.4% (68.2\u201398.3%)] but less specific [urine, 64.6% (51.7\u201375.8%); serum, 52.1% (37.4\u201366.5%)] for disease remission. Urine antigen was positive in both cats and serum antigen was positive in 1 cat at the time of disease relapse.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions and Clinical Importance<\/jats:title>\n                    <jats:p>Measurement of Histoplasma antigen in urine and serum might be useful tests for determining disease remission and relapse in cats with histoplasmosis.
