摘要
A method for assaying a heparin-induced thrombocytopenia (HIT) in a patient's serum or plasma sample, the method comprising: incubating a mix of platelets with the patient's serum or plasma sample in the presence of either a low concentration of heparin or a high concentration of heparin; incubating a mix of platelets in the presence or absence of a platelet activator; quantifying platelets and activated platelets in the mixes; calculating percentage of activated platelets within the platelets for each of the mixes; calculating a heparin platelet activation (HEPLA) index using the calculated percentages; measuring and calculating HEPLA indices of serum or plasma samples from donors not suffering from HIT; calculating cut-off values from the HEPLA indices of serum or plasma samples from donors not suffering from HIT, and determining whether a patient suffers of HIT or not by comparing the HEPLA index of the patient with the cut-off values.
