Description
Summary:Background Genital tuberculosis is one of the leading causes of female infertility. Paucibacillary nature of the disease in the female genital system often makes its diagnosis difficult. No single test has been able to accurately diagnose genital tuberculosis. In this study we aim to compare conventional diagnostic tests for tuberculosis like Acid Fast Bacilli (AFB) Staining, Lowenstein Jensen (LJ) Culture and Histopathology with newer tests like PCR, MGIT 960, GeneXpert. Methods This study included 67 infertile women from Vardhman Mahavir Medical College and Safdarjung Hospital, New Delhi. They were subjected to detailed history and routine investigations, namely Haemogram, ESR, Mantoux test, Chest X-ray and pelvic ultrasound to look for the findings of tuberculosis. A premenstrual endometrial aspirate was taken and was subjected to the AFB Staining, LJ Culture, Histopathology, PCR, MGIT 960, Gene Xpert, and the test results were compared. Result and Conclusion 35.8% (24/67) of women were diagnosed with genital tuberculosis using the diagnostic criteria. With culture as the gold standard, the positivity of genital TB was 19.4% (13/67). Majority of infertile patients with low index of suspicion clinically were positive for genital tuberculosis. Therefore, all the patients of infertility should be routinely evaluated for genital tuberculosis. PCR and MGIT 960 have shown promising results in the newer methods. LJ culture and histopathology are still the most reliable and available diagnostic methods. The usefulness of AFB Staining and GeneXpert remains questionable.
