False positivity for Aspergillus
antigenemia related to the administration of piperacillin/tazobactam.
There can be an absence of
antigenemia and antigenuria in immunocompromised patients with histoplasmosis, and therefore histopathology and cultures remain the gold standards for making a definitive diagnosis.
Rotavirus infection is usually localized to the intestine; however, some studies have reported
antigenemia or viremia in children with rotavirus diarrhea [8, 9].
The CMV antigen pp65 (
antigenemia method of C10C11) was detectable at a level of 33 positive cells per 150,000 cells and 25 positive cells per 150,000 cells, which confirmed her diagnosis of acute CMV infection.
(31-33) In contrast, for prevention of CMV disease in solid organ and HPC transplant patients, evidence-based guidelines support using either CMV prophylaxis or a preemptive approach using CMV
antigenemia or PCR monitoring with immediate treatment for evidence of viral replication.
