Endometrial inflammation cannot be detected by routine blood tests. Its diagnosis is mainly based on diagnostic scraping, where the scraped out endometrial tissues are sent for pathological tests, and only if the pathological diagnosis indicates the presence of endometrial inflammation can the diagnosis be made. If ultrasound examination reveals uneven echogenicity of the endometrium, thickening of the endometrium, or if the color of menstrual blood is lighter when menstruation occurs, or if there are corresponding symptoms such as dysmenorrhea, the possibility of endometrial inflammation can only be suspected, but the diagnosis cannot be confirmed, and the final clinical diagnosis is based on pathological diagnosis. Moreover, the clinical treatment of endometrial inflammation is relatively troublesome and can be given by intrauterine injection or intravenous medication.
