Abstract
Appendicitis can be detected by determining a threshold presence of the urinary pigment uroerythrin, in the urine of persons suspected of having appendicitis. The threshold presence of uroerythrin can be determined by precipitation of a sediment having a pink to red color. Additional qualitative, semiquantitative, or quantitative methods including HPLC (high pressure liquid chromatography), TLC (thin layer chromatography), radioimmunoassay, colorimetric tests, NMR (nuclear magnetic resonance), mass spectrometry, electrophoresis, monoclonal antibody tests, and other enzymatic tests may also be employed to measure uroerythrin levels.
