Osteocolloid (CY211)

Serum osteocollin, a kind of epithelial scaffold protein with molecular mass (40-70) KD, is a kind of intermediate filament constituting the cytoskeleton. There are many types, and there are more than 20 kinds known, named CYK1. -20, the most abundant tumor cells are CUL19 and CYK19. They are abundantly expressed in the serum of lung cancer patients, which has important clinical significance for the diagnosis, treatment and recovery of lung cancer. CY211-osteogen is an important indicator for the diagnosis of lung cancer. Basic Information Specialist classification: growth and development examination classification: blood examination Applicable gender: whether men and women apply fasting: fasting Tips: Forbidden overeating, spicy food, stimulating wine or strenuous exercise before check. Normal value [Reference value] <3.3 ng/mI. Clinical significance Abnormal results CY211 is a new tumor marker for detecting lung cancer, especially for the diagnosis of non-small cell lung cancer, with a specificity of 87%. Serum CY211 concentration and sensitivity increased with the progress of the disease. From a histological point of view, CY211 has a sensitivity of 76.5% to squamous cell lung cancer, which can distinguish lung squamous cell carcinoma and benign lung disease well, and its concentration is high and low. It is closely related to the staging of lung squamous cell carcinoma. In addition, the combination of CY211 and CEA can increase the detection sensitivity of lung adenocarcinoma to 55%. Precautions Taboo before the examination: blood test in the morning on an empty stomach. Taboo overeating, spicy food, stimulating wine or strenuous exercise. Requirements for examination: venous blood is taken on an empty stomach and obeyed by the doctor. Inspection process 3 ml of fasting venous blood was taken in the morning, and the serum was taken for 1 h after centrifugation. Not suitable for the crowd Generally suitable for middle-aged and elderly people, especially women. Adverse reactions and risks Dizziness or fainting: When blood is drawn, due to emotional overstress, fear, reflex caused by vagus nerve excitability, blood pressure drop, etc., the blood supply to the brain is insufficient to cause fainting or dizziness.
