tumor specific growth factor

Tumor-specific growth factor (TSGF) is a factor that promotes the proliferation of tumors and peripheral capillaries and releases them into peripheral blood during malignant tumor formation and growth. It is the result of massive expansion of malignant tumors and peripheral capillaries. Tumor-specific growth factor test procedure: Take 40 μl of serum to be tested, add 1 ml of reagent, place in boiling water bath for 15 min, cool in tap water for 5 min, centrifuge at 8000 rpm for 8-10 min, and absorb the supernatant to measure absorbance in UV spectrophotometer. Wavelength 470nm colorimetric, check the standard curve, find the corresponding TSGF content, while taking the known TSGF content of the serum as a quality control tube, the content of ≥ 64μ / ml is positive. Basic Information Specialist classification: Oncology examination classification: immune examination Applicable gender: whether men and women apply fasting: fasting Tips: Stop taking the treatment of the tumor, and stop the radiation treatment of the tumor for 24 hours. Normal value The normal value is 0-64 U/ml. Clinical significance Abnormal results: Serum TSGF is a new, highly sensitive broad-spectrum tumor marker with a simple and rapid detection method and stable results. It has important application value for primary screening and early diagnosis of digestive tract malignant tumors, and is a reliable indicator for identifying benign and malignant tumors. At the same time, continuous and dynamic monitoring of TSGF during the treatment of malignant tumors can reduce the blindness of radiotherapy and chemotherapy, and help to develop correct and effective treatment options. People who need to be examined: all cancer patients, especially those with malignant tumors. Precautions Pre-examination contraindications: Stop taking the treatment of the tumor, and stop the radiation treatment of the tumor for 24 hours. Requirements for examination: Keep the blood sample purity and take time to extract serum samples. Inspection process Take 40 μl of the serum of the specimen, add 1 ml of the reagent, set a boiling water bath for 15 min, cool the tap water for 5 min, centrifuge at 8000 rpm for 8-10 min, and absorb the supernatant to measure the absorbance in an ultraviolet spectrophotometer. Wavelength 470nm colorimetric, check the standard curve, find the corresponding TSGF content, while taking the known TSGF content of the serum as a quality control tube, the content of ≥ 64μ / ml is positive. Not suitable for the crowd Inappropriate crowd: None. Adverse reactions and risks There are no related complications and hazards.
