A urinalysis is a common screening tool for a urinary tract infection. The gold standard is a urine culture. A physician's office wanted to evaluate how well their screening did. One thousand (2,000) patients were screened for a urinary tract infection using. All 2,000 samples were also sent for a urine culture. The culture (gold standard) showed 500 patients had a urinary tract infection and of those 430 had a positive urinalysis (i.e. true positives). A total of 660 had a positive screening test. +2x2 table ● Total A C A+C B D B+D Total Create a 2x2 table with these data. Calculate the sensitivity of the test.
