Limitations:
Only serum or citrated plasma is accepted for testing. Positive test
results are not absolutely diagnostic of drug-induced thrombocytopenia
and must be used in combination with clinical information to make a
diagnosis. Negative results do not completely rule out a diagnosis of
drug-induced immune thrombocytopenia.
Methodology:
Immunofluorescence by Flow Cytometry
