Diagnostic Value of Peripheral Blood Smear Tests in Identifying Candida Infections in a Tertiary Care Setting: A Case Series.

Invasive fungal infections (IFIs) are a significant cause of morbidity and mortality in hospitalized patients, particularly among neonates and immunocompromised individuals.  species are one of the most commonly associated pathogens associated with IFIs. We present a case series of four patients with IFIs. All cases underwent peripheral blood film (PBF) examination, blood culture, and serum galactomannan testing. Budding yeasts were found in the PBF of three out of four cases. The findings were confirmed by culture. While blood culture remains the gold standard for diagnosing IFIs, the PBF test demonstrated its value as a rapid and cost-effective initial screening tool, especially in resource-limited settings. PBF tests can offer valuable preliminary insights, facilitating further diagnostic evaluation and early initiation of antifungal therapy. These findings underscore the potential utility of PBF tests in the early detection and management of IFIs.
