Is urinary @entity1130 helpful for early diagnosis of XXXX ?

@entity1 @entity32 @entity697 @entity698 @entity5581 @entity750 @entity1130
OBJECTIVE: @entity697 is the most common abdominal emergency in @entity1 and young adults. There are a lot of @entity750 -containing cells in the appendix, which release @entity750 into the bloodstream in response to @entity32 . Consequently, @entity750 is converted to @entity1130 ( @entity5581 ) and secreted into the urine. On this basis, urinary @entity5581 could be a marker for @entity697 . In this study, we investigated the value of @entity5581 levels in spot urine in the diagnosis of @entity697 . METHODS: The urinary @entity5581 was measured by an enzyme-linked immunosorbent assay in the spot urine of 70 @entity1 who presented to the emergency department with a clinical picture of @entity697 . Urine concentration results were correlated to final histopathologic reports, and the diagnostic value of this factor was measured. RESULTS: Diagnosis of @entity698 was confirmed by histopathologic reports in 59 of 70 @entity1 with presumptive diagnosis of @entity698 . Considering 5.25 mg/L as the cutoff point for urinary @entity5581 , 28 @entity1 had high urinary @entity5581 levels, whereas 42 @entity1 had values within reference range. The sensitivity and specificity of this test was 44% and 81%, respectively. CONCLUSIONS: The measurement of urinary @entity5581 levels is not an ideal diagnostic tool for ruling out or determination of @entity697 .
