SUMMARY OBJECTIVE: This study aimed to compare the serum samples found reactive (≥1-≤20 signal-to-cutoff ratio) with Elecsys antibodies to hepatitis C virus screening test with innogenetics-line immunassay hepatitis C Virus Score test and to determine the most appropriate threshold value for...
SUMMARY Falsely elevated estradiol is rare, may result from heterophile antibody interference, and can result in unnecessary investigation and intervention. We present the case of a 56-year-old female with falsely elevated estradiol levels inconsistent with her overall clinical picture, which ultimately ...

ABSTRACT Introduction: Lupus nephritis (LN) is one of the most prevalent and severe complications of systemic lupus erythematosus (SLE), requiring reliable urine and serum biomarkers to evaluate it. Anti-nucleosome and anti-C1q antibodies are associated with LN in several geographic regions. Also, sout...
Abstract Invasive Streptococcus pyogenes diseases represent the most severe form of infection produced by this microorganism. Early diagnosis and treatment are important, due to its potential severity. Etiological confirmation of invasive infection is performed by culture, which takes between 18 and 48 h...
