The Blinking Test (Faheem’s Approach) : A Promising Tool for Assessing Tubal Patency and Blockage

Objective: To evaluate the specificity and sensitivity of hysteroscopic tubal patency assessment using the tubal ostium movement (blinking test). Method This cross-sectional study was conducted at the Aswan Specialized Hospital, Aswan. Egypt and involved 55 infertile patients in the period from Jan 2022 to Mars 2022. Participants were recruited from the outpatient population visiting the gynecological clinic at ABC Fertility Center. Those who underwent hysteroscopy were further offered laparoscopic chromopertubation to complete the assessment, all within the same setting. Results The blinking test showed a sensitivity of 82.50% for detecting right tubal patency and 92.31% for detecting left tubal patency, along with a specificity of 100% for both right and left tubal patency. Both the positive predictive value and negative predictive value were 100%. The overall accuracy of the blinking test was 87.27% for right tubal patency and 94.55% for left tubal patency. Furthermore, the blinking test's diagnostic value was supported by the favorable area under the curve (AUC) values, ranging from 0.87 to 0.961 in the ROC curve analysis. Conclusion The blinking test has shown promising results as a diagnostic method for assessing tubal patency in infertile patients. It is a useful tool for assessing tubal factor infertility because of its excellent sensitivity, specificity, positive predictive value, negative predictive value, and accuracy.
