To evaluate the diagnostic efficiency of circulating endometrial cell detection method using microfluidic chip as an non-invasive method for diagnosis in endometriosis.

Endometriosis is a chronic condition, characterized by the presence of functional endometrial glands and interstitium in extrauterine ectopia. Ectopic endometrial tissue responds to estradiol and other hormones similar to normal endometrium. Endometriosis is one of the most common benign gynaecological conditions, affecting up to 5 to 10 percent of women of reproductive age. In addition to severe dysmenorrhea or pelvic pain, decreased fertility is a common clinical manifestation of internal heterogeneity, with up to 40 percent of patients associated with infertility . Currently, laparoscopy is the gold standard for diagnosis. However, the actual time to diagnosis in patients with internal dysmorphia is delayed by an average of 4 to 11 years, resulting in a large number of patients with moderate to severe (stage III to IV) at diagnosis. Recently, the exploration of efficient and cost-effective non-invasive diagnostic solutions has been a hot button issue.
