CA-125 was initially detected using the murine monoclonal antibody designated OC125. Robert Bast , Robert Knapp and their research team first isolated this monoclonal antibody in 1981. [ 28 ] The protein was named "cancer antigen 125" because OC125 was the 125th antibody produced against the ovarian cancer cell line that was being studied.
Blood test results should always be interpreted using the reference range provided by the laboratory that performed the test. [1] ... CA-125: 30, [71] 35 [72]
The reason is that the test may be falsely normal (false negative) in many cases or abnormally elevated in people who have no cancer (false positive) in others. The main use of CA19-9 is therefore to see whether a pancreatic tumor is secreting it; if that is the case, then the levels should fall when the tumor is treated, and they may rise ...
A blood test is a laboratory analysis performed on a blood sample that is usually extracted from a vein in the arm using a hypodermic needle, or via fingerprick. Multiple tests for specific blood components, such as a glucose test or a cholesterol test , are often grouped together into one test panel called a blood panel or blood work .
The one biomarker that has been in use over the last 20 years is CA-125. [121] A 2016 review found that this biomarker was present in those with symptoms of endometriosis; and, once ovarian cancer has been ruled out, a positive CA-125 may confirm the diagnosis. [122] Its performance in ruling out endometriosis is low. [122]

A complete blood count (CBC), also known as a full blood count (FBC), is a set of medical laboratory tests that provide information about the cells in a person's blood.The CBC indicates the counts of white blood cells, red blood cells and platelets, the concentration of hemoglobin, and the hematocrit (the volume percentage of red blood cells).
CA 242 is a tumor marker for sialylated Lewis carbohydrates associated with adenocarcinomas and e-selectin-mediated metastatic risk. [ 1 ] [ 2 ] [ 3 ] It is commonly tested along with CEA, CA19-9 , and CA242 for detecting pancreatic cancer . [ 4 ]
