Novacyt's protein diagnostics division, Lab21, has launched a new product for the diagnosis of infectious mononucleosis (IM), or glandular fever. The product, PathFlow Mononucleosis, is a qualitative lateral flow immunoassay for the detection of IM antibodies in the blood. IM is frequently misdiagnosed as streptococcal pharyngitis, a bacterial infection, due to common clinical presentation of the diseases at onset. However, Epstein–Barr, a virus, causes infectious mononucleosis, so it doesn't respond to antibiotic treatment. PathFlow Mononucleosis provides a rapid and effective differential diagnosis to patients with IM over streptococcal pharyngitis, Novacyt said.
