Welcome to the gastroenterology community! Please be patient in waiting for a reply. We are all volunteers here just helping out in our spare time. Those results all look fine to me. I don't know of a test called "ABN". Are you sure ABN wasn't under another test and stood for "abnormal"?
Thanks 915, The lab report has 5 columns and one is ABN that I don't know, the rest are Test, Results, References and Unit, so ABN is not a test as you imagined. I have also that remark "high" under ABN on the test of my uric acid result, 7.4, reference 3.5-8.5 so I don't understand still. Thanks again and I'll wait for more explanation.
