Tissue polypeptide specific antigen

There are many professional terms in medicine that sound very complicated, and tissue polypeptide-specific antigen is one of them. Although tissue polypeptide-specific antigen is very complex, it is a component that can reflect many cancer diseases in the human body. When a woman has breast cancer, etc., it can be judged by checking whether the tissue polypeptide-specific antigen is normal. So what exactly is tissue polypeptide-specific antigen?

Tissue Polypeptide Specific Antigen (tps) is a polypeptide antigen secreted by tumor cells.

Reference range

<55mU/ml (ELISA)

Clinical significance

1. TPS is generally found to be elevated in the serum of patients with ovarian cancer, and other patients such as lung cancer and breast cancer may also have elevated serum levels;

2. TPS is used together with other markers as an auxiliary indicator for diagnosing and tracking tumors and disease changes.

What is the reason for the high tissue polypeptide specific antigen?

It may be a normal physiological phenomenon, or it may be a tumor.

Tissue polypeptide-specific antigen is the specific part of TPA in the blood. When cells proliferate, in the late S and G2 phases of the cell cycle, this high level may be a physiological phenomenon, such as during pregnancy, or it may be caused by benign or malignant tumors.

Tissue polypeptide-specific antigen is a polypeptide antigen secreted by tumor cells. Tissue polypeptide-specific antigens can be used together with other tumor markers as auxiliary indicators for diagnosing tumors and disease changes. Tissue polypeptide-specific antigen may be elevated in the serum of patients with ovarian cancer, and may also be elevated in patients with other cancers such as lung cancer and breast cancer.

Normal value of tissue polypeptide antigen (TPS): serum: <120U/L (enzyme-linked immunosorbent assay). (Note: The specific reference value shall be determined by each laboratory.) Guidance: Clinical significance of tissue polypeptide antigen (TPS): Elevated: seen in lung cancer, bladder cancer, prostate cancer, breast cancer, ovarian cancer, acute hepatitis, pancreatitis, pneumonia, digestive tract tumors. In addition: The positive rate in normal people is 4.7%. However, a considerable number of non-malignant tumor patients have TPS in their serum, with a positive rate of about 14% to 35%.
