FBC rose test

A method for detecting human T lymphocytes. The surface of human T lymphocytes has red blood cell receptors, which can spontaneously combine with sheep red blood cells to form rose petals, hence the name. These receptors are synthesized by living cells, and lose the formation of E-roses after the cells die. This response is a unique hallmark of human T lymphocytes. The cellular immunity of the T cell body, when the results of the E-rose test in the blood are significantly reduced, indicates a decrease in the level of cellular immunity. Basic Information Specialist classification: cardiovascular examination classification: immune examination Applicable gender: whether men and women apply fasting: fasting Tips: Forbidden to overeating, ask for an empty stomach blood test in the morning. Normal value The reference value is 10% to 25%. Clinical significance Abnormal results: When the humoral immune deficiency, the percentage of FBC rose cells formed decreased significantly; in some autoimmune patients producing autoantibodies, the percentage of FBC rosette cells increased significantly; chronic lymphocytic leukemia patients, peripheral blood The percentage of FBC rose forming cells was significantly increased. People who need to be examined: immunodeficient patients, and patients with related diseases need to be examined. Precautions Taboo before the test: taboo overeating, requiring fasting blood test in the morning. Requirements for examination: The blood sample to be tested must be fresh and sterile. It is required to be tested within 3h~4h after blood collection. Otherwise, the receptor will fall off due to the death of lymphocytes, which will affect the test results. Inspection process Whole blood count (FBC) is a series of tests used to determine the composition and amount of cells in the blood, including: red blood cell count (RBC). The number of red blood cells was counted using the whole blood count after the rose test, and the test basis was used. Not suitable for the crowd Inappropriate people: no special requirements. Adverse reactions and risks There are no related complications and hazards.
