The main way for women to test themselves for gynaecological disease is through clinical manifestations. Patients with gynaecological disease usually have abnormal leucorrhoea or abnormal vaginal discharge with a bad odour, as well as symptoms such as vulvar itching, abnormal menstruation or abdominal and back pain, which in severe cases may make it difficult to have children normally. If a woman has no abnormal discharge from the vagina, no symptoms such as itching, burning or pain, no significant pain in the abdomen or lumbosacral region and normal menstruation, it usually indicates that there is no gynaecological disease. However, judging by clinical manifestations is not absolute, and a clear diagnosis through relevant tests is needed.
