What is CA 125 half life?

What is CA 125 half life?

Median (range) for CA 125 kinetics were: 263 kU/l (5-52000 kU/l) before 1st course, 15.8 days (4.5-417.9 days) for CA 125 half-life, 16 kU/l (3-2610 kU/l) for nadir and 85 days (0-361 days) for time to nadir.

What is CA 125 CEA?

A CA 125 test measures the amount of the protein CA 125 (cancer antigen 125) in the blood. This test may be used to monitor certain cancers during and after treatment. In some situations, the test may be used to look for early signs of ovarian cancer in people with a very high risk of the disease.

What is the sensitivity of the new CA 125 test?

The sensitivity for the CA125 serum concentration in predicting malignancy was 75.97% (95% CI, 67.50–82.86%), specificity was 79.59% (95% CI, 73.13–84.86%), positive predictive value (PPV) was 71.01% (95% CI, 62.58–78.26%), negative predictive value (NPV) was 83.42% (95% CI, 77.14–88.30%), positive likelihood ratio (LR …

Is CA 125 same as CEA?

Since serum CA-125 levels and serum CEA levels are not up to the mark for distinguishing ovarian malignancies from non- ovarian malignancies their ratio (CA-125/CEA) is a better marker for differentiating the same.

What is a good CA-125 number?

Generally speaking, the normal range of CA-125 is considered to be 0-35 units/mL, while a level above 35 units/mL is considered to be a high CA-125 level.

What is normal range for CA-125?

What cancers can CA-125 detect?

Cancer antigen 125 (CA125) is a protein found on most ovarian cancer cells that is secreted into the blood stream and can be measured….The CA125 blood levels can be increased in ovarian cancer and other cancers including:

  • uterine.
  • fallopian tube.
  • pancreatic.
  • breast.
  • colorectal.
  • lung.
  • stomach.

What is a normal CA-125 level?

What cancers does CA-125 detect?

What is normal range of CA-125 test?

CA-125 normal range The range of 0 to 35 U/mL is considered within the normal guidelines. Levels over 35 U/mL may indicate the presence of cancer or other conditions. Not all patients with a high CA-125 result have cancer.
