Chromogranin A (CgA) laboratory test<\/h1>\n\t
\n\t\t
\n\t\t\t

The Chromogranin A (CgA) test can be used to diagnose carcinoid tumours and other tumours originating from neuroendocrine cells, and to monitor the effectiveness of the therapy of the disease being treated.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n<\/div><\/div><\/div><\/div>

What do we mean by a neuroendocrine tumour?<\/h2>\n\t
\n\t\t
\n\t\t\t

Neuroendocrine cells are found in many parts of the body and work through nervous and hormonal regulation. Neuroendocrine tumours develop in these cells and form a rare subgroup of cancerous diseases.<\/p>\n

This group of tumours must be distinguished from other tumour types, as neuroendocrine tumours in almost all cases produce – or have the potential to produce – hormone-like substances that most tumours do not.<\/p>\n

These hormone-like substances are produced continuously or intermittently by ill cells and enter the bloodstream, therefore they can be detected by a specific blood test.<\/p>\n

Neuroendocrine tumours can occur in almost all organs of the human body, most commonly from the gastrointestinal tract and the mucous membranes of the pancreas and bronchial system.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n<\/div><\/div><\/div>

What are carcinoid tumours?<\/h2>\n\t
\n\t\t
\n\t\t\t

Carcinoid tumours are one of the most common types of neuroendocrine tumours, usually developing in the digestive system (stomach, small intestine, colon, rectum) or lung. They do not cause symptoms for a long time, or only milder symptoms appear depending on the location of the tumour.<\/p>\n

Common symptoms of tumours in the lungs include shortness of breath, chest pain, wheezing, and redness on the face and neck. Long-term abdominal pain and severe diarrhoea and redness of the face are typical of gastrointestinal tumours.<\/p>\n

The occurrence of symptoms is often attributed to irritable bowel syndrome, so it is recommended that a chromogranin test be performed if these symptoms persist.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n
