False-seronegative HCV infection motivated by interference with cryoglobulins
Abstract
Cryoglobulins (CGs) are serum proteins that undergo a reverse cold-induced precipitation in vitro. The CGs are a well-known cause of analytical interferences in several laboratory tests, leading to spurious results. With this in view, we present a case of a patient initially misdiagnosed due to CGs interference in Hepatitis C Virus (HCV) serology.
