A 1984 study first described the use of DCP as a marker of hepatocellular carcinoma (HCC); it was present in 91% of HCC patients, while not being detectable in other liver diseases. The DCP level did not change with the administration of vitamin K, suggesting a defect in gamma-carboxylation activity rather than vitamin K deficiency. [ 1 ]
Tumor markers can be determined in serum or rarely in urine or other body fluids, often by immunoassay, but other techniques such as enzyme activity determination are sometimes used. Assaying tumor markers were significantly improved after the creation of ELISA and RIA techniques and the advancement of monoclonal antibodies in the 1960s ...
PACVs were first deployed to Vietnam in May 1966 as PACV Division 107, Task Force 116, where they were used by the Navy for riverine patrol missions in the Mekong Delta and on the Mekong River. [ 26 ] : 15 Often called "Pac Vees", they were armed with a .50 caliber machine gun mounted on a rotating platform in the front and two side-mounted M60 ...
Guidelines from the American Society of Clinical Oncology discourage the use of CA19-9 as a screening test for cancer, particularly pancreatic cancer.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.
Coagulation activation markers are biomarkers of net activation of coagulation and fibrinolysis. [ 1 ] [ 2 ] Examples include prothrombin fragment 1+2 (F1+2), thrombin–antithrombin complex (TAT), fibrinopeptide A (FpA), fibrin monomers (FMs), plasmin-α 2 -antiplasmin complex (PAP), activated protein C–protein C inhibitor (APC-PCI), and D ...

A biomarker may be used to see how well the body responds to a treatment for a disease or condition. Also called molecular marker and signature molecule." [18] In cancer research and medicine, biomarkers are used in three primary ways: [19] To help diagnose conditions, as in the case of identifying early stage cancers (diagnostic)
In medicine, a biomarker is a measurable indicator of the severity or presence of some disease state. It may be defined as a "cellular, biochemical or molecular alteration in cells, tissues or fluids that can be measured and evaluated to indicate normal biological processes, pathogenic processes, or pharmacological responses to a therapeutic intervention."
