A “cold” platelet agglutinin is described reacts only at temperatures below 34#{176}C. which is present in plasma and serum, It agglutinates homologous and autois greater than 100,000 in molecular logous platelets but appears to have no weight, appears to be a protein of the imeffect on in vivo platelet function. It is munoglobulin type, is adsorbed by plateseen in patients with systemic diseas...
متن کاملPseudothrombocytopenia Caused by Platelet Agglutinins That Are Reactive in Blood
The phenomenon of in vitro platelet clumping and consequent pseudothrombocytopenia in the presence of EDTA was studied in the plasmas and sera of three patients. A heterogeneity was identified among these platelet agglutinins. lgG agglutinins present in two patients recognized antigens that were present when EDTA was added to platelets. This effect of EDTA did not appear to be mediated by calci...
