Tests
The determination of the amount of sialyl SSEA-1 antigen present in a sample.
Tests
The determination of the amount of soluble B cell maturation antigen present in a sample.
Tests
The determination of the amount of soluble lymphocyte activation gene-3 in a sample.
Indicators
Soluble monocyte differentiation antigen CD14 is encoded by the human CD14 gene. This soluble protein may be used as a marker of monocyte activation and is derived either through cleavage that removes the glycophosphoinositol (GPI)-anchor from the membrane bound form of CD14 or as non-cleaved form secreted from the non-GPI-modified intracellular pool of CD14.
Indicators
A secreted antigen derived from two nearly identical cytoplasmic glycoproteins of the serpin family, serpin B3 (SCCA-1) and serpin B4 (SCCA-2). These proteins are specifically expressed in normal squamous epithelia and are present at elevated concentrations in the serum of subjects with squamous cell carcinoma and certain inflammatory and autoimmune diseases. This antigen was first described in squamous cell cervical carcinoma; it is currently used as a nonspecific tumor marker for the presence, staging and monitoring of the disease course for squamous cell carcinomas of the head and neck, cervix, esophagus, anus and lung.

Tests
The determination of the amount of lymphocyte antigen T1/Leu-1 in a sample.
Indicators
Tumor-associated oncofetal glycoprotein 72 (TAG-72) is a high molecular weight (220-400 kD) complex expressed by a wide variety of human adenocarcinomas. This antigen is expressed by a majority of invasive ductal breast carcinomas, and most colon, pancreatic, gastric, esophageal, lung (non-small cell), ovarian and endometrial adenocarcinomas, and on normal secretory endometrium, but not on other normal tissues. It is not expressed by leukemias, lymphomas, sarcomas, mesotheliomas, melanomas or benign tumors. The monoclonal antibodies against TAG-72 have been widely employed for the immunohistochemical analysis of adenocarcinomas as well as for radioimmunoscintigraphy and radioimmunoguided surgery.
