Problems solved by technology

The main disadvantages of the former are: the accuracy of the inspection is limited by the level of the operator, high misdiagnosis rate (15-55%), pain for the examinee, and long inspection cycle; although the latter has a high sensitivity (>90%), but Low specificity (<50%), i.e. inability to distinguish benign epithelial changes from malignant tumors
Even taking peripheral blood like measuring blood sugar, repeated testing will cause great harm to patients

Embodiment Construction

[0018] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below. It should be understood that the specific embodiments described here are only used to explain the present invention, and are not intended to limit the present invention.

[0019] This specific embodiment adopts the following technical solutions:

[0020] Cut off about 2 square centimeters of the sanitary napkin with menstrual blood, and pay attention to cutting off the absorbent cotton. Place the cut sanitary napkin in 10ml of normal saline and shake it on a shaker for 10 minutes. Filter through a 300-mesh filter. Take 10 microliters of filtered liquid for red blood cell count. Divide the number of red blood cells obtained by 250,000 to get the amount of menstrual blood (in ml). After the menstrual blood is obtained, the red blood cells in the menstrual blood can be counted. The quantitative method is that...

Abstract

The invention discloses a cervical cancer screening method, which comprises the following steps of: taking menstrual blood, and detecting CA15-3(Carbohydrate antigen 15-3, carbohydrate antigen 15-3), CEA (Carcino-embryonic antigen), CA125 (Carbohydrate antigen 125), CYFRA21-1 (cytokeratin 19 fragment, cytokeratin fragment), squamous cell carcinoma associated antigen (SCCA), Her-2 (human epidermal growth factor receptor-2 of protooncogene), TP53 (Tumor protein 53) gene, APC (Adenomatous polyposis coli) gene, HPV DNA gene, and TCT(liquid based cytology) detection in the menstrual blood, and the illness risk of cervical cancer can be prompted. The method has no radiation damage to human bodies, and is short in detection time and low in cost. As the menstrual blood is very convenient and noninvasive to obtain, women can detect once a month, so that the women can know the risk of cervical cancer as soon as possible and take prevention and treatment measures.

Description

technical field [0001] The invention relates to the technical field of cervical cancer, in particular to a screening method for cervical cancer. Background technique [0002] Cervical cancer ranks second in cancer mortality among women worldwide. In developing countries, due to the imperfection of cervical screening, the incidence of cervical cancer is six times that of developed countries, and its death rate ranks first among women's cancers. According to the screening results of tens of thousands of patients with cervical lesions conducted by relevant experts from Beijing Friendship Hospital, the age distribution of cervical cancer patients is 34-48 years old, of which 33.3% are under 40 years old, and 66.6% are 40-48 years old. %, which shows that cervical cancer has seriously threatened the health and life of young and middle-aged women. [0003] The traditional methods of cervical examination mainly include Pap smear method and colposcopy. The main disadvantages of t...
