what the risks are direct immunofluorescence, e-rosetting, t and b lymphocyte assays, b and t lymphocyte assays, a test that makes a quantitative measurement of t and b lymphocytes, in the blood, blood is drawn, a vein, the elbow, the hand, puncture site is cleaned, antiseptic, an elastic band, around the upper arm to cause the vein to swell, blood, a needle is inserted, vein, blood is collected in air-tight vials, a syringe, band is removed, restore circulation, once the blood has been collected, needle is removed, puncture site is covered to stop any bleeding, blood could also be obtained by capillary sample, fingerstick, heelstick in infants, blood is drawn it goes, a two step process, lymphocytes, separated from other blood elements, once the cells, separated, identifiers, added to distinguish between t and b lymphocytes, e-rosetting test identifies t cells, direct immunofluorescence, identify b cells, no alteration in diet is necessary, inform health care provider of in life that might affect t and b cell count, x-rays, chemotherapy, surgery, steroid therapy, stress , the needle is inserted to draw blood, feel moderate pain, others feel only a prick, stinging sensation, some throbbing, this test is performed to aid health care provider, in the diagnosis of immunodeficiency diseases, distinguish between benign, malignant lymphocytic disease, test performed to monitor response to therapy, values, from laboratory to laboratory, depend on testing technique, t cells comprise 68% to 75% of total lymphocytes, b cells 10% to 20%, abnormal t and b cell counts suggest possible diseases, further testing is indicated to confirm any, the suggested diagnosis, an increased t cell count, suggest, infectious mononucleosis, multiple myeloma, acute lymphoblastic leukemia, an increased b cell count, suggest, chronic lymphocytic leukemia, multiple myeloma, waldenstrom's macroglobulinemia, digeorge syndrome, a decreased t cell count, suggest, congenital t-cell deficiency disease nezelof syndrome, digeorge syndrome, wiskott-aldrich syndrome, b cell proliferative disorders acquired immunodeficiency syndrome, chronic lymphocytic leukemia, waldenstrom's macroglobulinemia, a decreased b cell count, suggest, acute lymphoblastic leukemia, congenital immunoglobulin deficiency disorders, acquired immunoglobulin deficiency disorders, risks associated, venipuncture, slight, excessive bleeding, fainting, feeling light-headed, hematoma, blood accumulating under the skin, infection, a slight risk, the skin is broken, multiple punctures to locate veins, veins, arteries vary in size, obtaining a blood sample.
