The normal range of cy211, or osteopontin, is 0~3.3ng/ml. 3.58ng/ml is relatively high, but you can’t judge whether the organism is normal or not just by this item. cy211 is a tumor marker, so cy211 can be used as an auxiliary diagnosis of cancer, especially for the case of lung cancer. In addition, cy211 will gradually increase with the development of lung cancer, and cy211 may also increase due to staying up late and consuming too much stimulating food. 3.58ng/ml is relatively high, but because cy211 in lung cancer patients is usually 5 times or more higher than the normal value, when this situation occurs, if the lung imaging is normal, it is usually not cancer, and may be caused by staying up late or dietary factors. Patients should not be overly anxious, and need to change their lifestyle habits and undergo regular checkups. Once patients find that their cy211 is increased, they should seek medical treatment in time, identify the cause of the disease and then intervene under the guidance of the doctor to promote health.
