Task: Answer Verification
Input (English): Question: Is immunization against a low-frequency human platelet alloantigen in fetal alloimmune thrombocytopenia a single event : characterization by the combined use of reference DNA and novel allele-specific cell lines expressing recombinant antigens?
Answer: This study demonstrates that cases of FNAIT attributed to low-frequency PLT alloantigens cannot be regarded as single events. The availability of reference DNA and cell lines expressing recombinant PLT alloantigens can facilitate their identification.
Output (English): no
