Standard urine culture techniques that have been used in clinical microbiology since the 1950s are missing real infections and are being relied on by our doctors to 'mis'diagnose us. How frustrating for those of us who, despite our symptoms, have had repeated 'negative' tests that ruled out 'infection' and denied us of appropriate treatment. These tests need to be replaced urgently.
"Paper 11. False Negatives of Standard Urine Cultures May Delay Patient Treatment
October 2015
"Conclusions: For most women who felt they had a UTI, EQUC [expanded quantitative urine culture] more often detected a uropathogen than did SC [standard culture]. UTI symptom (severity and bother) improved after treatment with an antibiotic. Importantly, women who were SC-negative but EQUC- positive were not treated with antibiotics despite having a uropathogen. These women frequently had no symptom improvement or became worse. The UTISA post-questionnaire in conjunction with EQUC highlights the troublesome false negative rate of SC. Clinicians can improve patient care with the additional information available from EQUC.
