Growth charts 2 to 18 years. Maternal and Child Health nurses use percentile charts from the Centre for Disease Control for children between 2 and 18 years of age, which measure height, weight and Body Mass Index (BMI).MI is calculated using height and height measurements, then used to compare a childâs weight relative to height with other children of the same age and gender, using BMI percentile charts. The following equation can be used to determine BMI: BMI = Weight (kg) / height (m) Height (m).
Chromogranin A (CGA) is a protein found in and released from neuroendocrine cells. The Chromogranin A test is used as a tumor marker.It may be ordered in combination with or in place of serotonin to help as an aid to diagnose carcinoid syndrome. Typical carcinoid symptoms include: 1  Flushing. 2  Diarrhea. 3  Abdominal pain. 4  Wheezing. 5  Valvular heart disease.hromogranin A (CGA) is a protein found in and released from neuroendocrine cells.

The best known of the blood markers for pancreatic cancer is CA19-9, a âcarbohydrate associated antigenâ also known as a sialylated Lewis (a) antigen.This marker is somewhat uneven in the diagnosis of pancreatic cancer, but can be quite elevated in those with pancreatic cancer.Approximately 10% of Caucasians lack the Lewis antigen, so in them the CA19-9 is not expressed.urrently, some oncologists appear to feel that the best use of the CA19-9 marker is as a guide to follow the disease and treatment process in a given individual patient. There are mutations in specific DNA genes that are found commonly in pancreatic cancer. Some of these well-known genes are k-ras, p53 and p16.
