Absorption elution test results Note : titer before absorption detection were 642.5 gG anti- A, anti- ~ B 2 drops of the serum of patients with 5 l of the standard B- 1 drop of red blood cells mixed with 2 drops of the serum of patients 2 and 5 type A standard mixture of 1 drop of red blood cells , respectively,UGG laarzen, for indirect antiglobulin test , the results were negative . That patients with a serum IgG anti- non- B, 2 patients with no serum IgG anti- A. 2.6 blood transfusion polybrenc Act (Baso company) with blood. 1 patient with type A washed red blood cells lose 4U, apheresis platelet concentrates two type A treatment volume ; 2 patients with B- washed red blood cells lose 6U, two patients had no transfusion reactions . 2.7 Department investigation of two patients with a son a daughter ,ugg zapatos, patient 2, a child and a woman , 0 blood group antigen-antibody no exception. 2.8 According to the above results to determine the serological test results , to determine patient 1: blood type is A ( lack of anti- B); patient 2: AB0 blood type B ( absence of anti- A). 3 Discussion In general, human serum in the presence of blood group antibodies , with its own red blood cells lacking the corresponding A or B antigens , the immune system of people were outside the normal antigen stimulation, the system will not for their own antigens and antibodies , which can be the complementary relationship is expected to do with the serum anti- theoretical basis for stereotypes mouth j. MM is a malignant proliferation of abnormal plasma cells ,Abercrombie and Fitch, two patients have strains of M protein monoclonal peak ,moncler jassen, the patient 1IgM1.26g / L ( reference value 0.86 ~ 1.32g / I), IgM level is not low , the patient 2IgM not detected , but two patients lack ABO blood group antibodies, therefore , MM patients lack anti- a or anti- B and IgM relationships difficult to determine. Zhang Lini that the anti- A or anti- B-specific and only a portion of the M protein , not all patients had strains of M protein monoclonal peak of MM patients lack anti- A or anti- j. Normal serum immunoglobulin and specific antibody levels were significantly decreased in MM immunological characteristics of H. Therefore , the two patients, the lack of corresponding blood group antibodies , may be due to normal immunoglobulin and specific antibody levels were significantly decrease .
