Carcinoembryonic antigen (CEA) conversion calculator to µg/L, ng/L, ng/dL, ng/100mL, ng%, ng/mL units. Online converter from conventional to SI units | UNITSLAB.COM. CEA is a monomeric glycoprotein (molecular weight approximately 180000 daltons) with a variable carbohydrate component of approximately 45‑60 %.

CEA is a monomeric glycoprotein (molecular weight approximately 180000 daltons) with a variable carbohydrate component of approximately 45‑60 %. CEA, like AFP, belongs to the group of carcinofetal antigens that are produced during the embryonic and fetal period.

Carcinoembryonic antigen (CEA) describes a set of highly-related glycoproteins involved in cell adhesion. CEA is normally produced in gastrointestinal tissue during fetal development, but the production stops before birth. Consequently, CEA is usually present at very low levels in the blood of healthy adults (about 2–4 ng/mL). [2]

2024年12月11日 · Carcinoembryonic antigen (CEA) is a nonspecific serum biomarker that is elevated in many malignancies, including colorectal cancer, medullary thyroid cancer, breast cancer, and mucinous ovarian cancer.

CEA 是一种具有人类胚胎抗原特异性的酸性糖蛋白，于 1965 年由 Gold 和 Freedman首先从结肠癌和胚胎组织中提取的一种肿瘤相关抗原，随后在多种其他类型的肿瘤患者、有多年吸烟史的人群或有某些其他非恶性疾病患者的血液中均可检测到 CEA 的浓度升高。 其生理来源通常来源于胎儿的胚胎内胚层上皮，受胎儿致癌基因控制，常在出生后从血清中消失，然而，少量的 CEA 可能残留在结肠组织中，CEA及其相关基因（29个中其中18个正常表达）构成了人类的CEA家族， …

What is a CEA test? A carcinoembryonic antigen (CEA) test measures a specific blood glycoprotein called CEA. It means a protein with a lot of sugars added to it by normal or cancerous cells. Scientists first discovered CEA in 1968 when they isolated extracts of liver metastasized by colorectal cancer and also from normal fetal digestive tract.

Carcinoembryonic antigen unit conversion calculator – Convert Carcinoembryonic antigen (CEA) levels ng/mL to µg/L or µg/L to ng/mL. How to use Carcinoembryonic antigen Unit Conversion?

2021年11月15日 · A CEA test measures the level of carcinoembryonic antigen (CEA) in the blood or other body fluid. As a type of tumor marker, CEA is an indicator of whether cancer is growing and spreading or diminishing with treatment. It is also known as a CEA assay, CEA blood test and carcinoembryonic antigen test.

Monitoring colorectal cancer and selected other cancers such as medullary thyroid carcinoma. May be useful in assessing the effectiveness of chemotherapy or radiation treatment. This test is not useful for screening the general population for undetected cancers. Immunoenzymatic Assay.

This assay is intended for the in vitro quantitative determination of carcinoembryonic antigen in human serum and plasma. 1 The Elecsys CEA assay is further indicated for serial measurement of CEA to aid in the management of cancer patients. The main indication for CEA determinations is the follow-up and therapy-management of colorectal carcinoma.
