What is the normal range of CA-125?
What is the normal range of CA-125?
Results of the CA 125 test are measured in units per milliliter (U/mL). The normal value is less than 46 U/mL. If your CA 125 level is higher than normal, you may have a benign condition, or the test result could mean that you have ovarian, endometrial, peritoneal or fallopian tube cancer.
What is the highest CA-125 level?
The highest CA 125 level reported in proven endometriosis is 9537 U/ml following acute rupture of an endometrioma [7].
What level of CA-125 indicates endometriosis?
The mean serum CA-125 level of women with endometriosis was 49.93±4.30 U/mL (range, 2-191 U/mL).
Does low CA125 mean no cancer?
A decreasing CA125 level can indicate that the cancer is responding to treatment, whereas an increasing CA125 may indicate continued cancer growth.
What does ca 125 stand for in blood test?
Questions About Ovarian Cancer Screening CA-125, which stands for “Cancer Antigen 125” is a protein that may be found in high amounts in the blood of patients with ovarian cancer. CA-125 is produced on the surface of cells and is released in the blood stream.
What to do if your CA-125 level goes down?
1 Monitor treatment for ovarian cancer. If CA-125 levels go down, it usually means the treatment is working. 2 Check to see if cancer has come back after successful treatment. 3 Screen women who are at high risk for ovarian cancer.
Can a person with ca 125 not have cancer?
In other words, CA 125 may not be elevated in someone who does have cancer and can be elevated in someone who does not have cancer. Additionally, the number itself does not correlate with how much disease a person has. Two patients with the same level can have a widely differently extent of cancer.
What should the preoperative value of CA-125 be?
A preoperative value >65 U/mL suggests a poor prognosis. Persistent elevations following chemotherapy indicate a poor prognosis. The half-life of CA-125 after chemotherapy correlates with prognosis (patients with CA-125 half-life <20 days show improved survival).
