Introduction

CA125 testing is a tumor marker examination, and it is necessary for healthy individuals to undergo CA125 testing. The CA125 test requires a blood sample. It primarily reflects the metabolism and metastasis of solid malignant tumors. The normal range for CA125 is typically 0–35 U/ml, and under normal circumstances, CA125 levels in the blood are very low.

CA125 testing requires a blood sample. It primarily reflects the metabolism and metastasis of solid malignant tumors. The normal range for CA125 is typically 0–35 U/mL. Under normal circumstances, CA125 levels in the blood are very low and usually do not attract attention; levels only rise when tumors have progressed to a certain stage. Therefore, an elevated CA125 level should not be ignored as it may indicate the presence of disease. In most healthy adult women, serum CA125 levels are below 35 U/mL. If a patient's serum CA125 level is twice the baseline value, there may be ovarian pathology, and physical examinations are recommended promptly.

In addition, CA125 testing can help detect the presence of cancer cells in the body. It is important to have regular medical check-ups to ensure early detection and treatment, which can significantly improve treatment outcomes and help avoid complications caused by delayed treatment. During testing, individuals should avoid excessive psychological stress, stay relaxed, maintain a positive mindset, and cultivate an optimistic attitude.

What does the carbohydrate antigen CA125 test check for?

Carbohydrate antigen CA125 is primarily used to detect malignant tumors such as ovarian cancer, as well as benign conditions like uterine fibroids. Also known as cancer antigen 125, CA125 is a type of tumor marker. Elevated levels of this marker are commonly observed in various malignant tumors, including epithelial ovarian cancer, fallopian tube cancer, endometrial cancer, lung adenocarcinoma, and gastrointestinal adenocarcinomas.
