An Overview on Diagnosis of candida infections

Abstract

Candida infections represent a significant cause of morbidity and mortality, particularly among immunocompromised and critically ill patients. The diagnosis of candidiasis remains challenging due to the absence of specific clinical manifestations and the limitations of conventional diagnostic methods. Blood culture, although considered the gold standard, has low sensitivity and may yield negative results in a substantial proportion of invasive cases. Additionally, serological tests and antigen detection methods are often limited by rapid antigen clearance or cross-reactivity due to colonization. Recent advances in molecular and non-culture-based diagnostic techniques have improved the sensitivity and specificity of Candida detection; however, their high cost and technical requirements restrict widespread use. Accurate and early identification of Candida species is essential, as different species exhibit variable virulence and antifungal susceptibility patterns, directly impacting clinical management and therapeutic outcomes. Therefore, a combined diagnostic approach integrating microbiological, serological, histopathological, and molecular methods is often required to achieve optimal diagnosis and guide appropriate antifungal therapy.
