Non-culture based fungal diagnostic tests

Timely diagnosis of fungal infections is sometimes impaired by the slow growth in culture or low yield of culture for certain organisms. Let’s discuss some of the non-culture based fungal diagnostic tests that are available in clinical microbiology laboratories.

Bloodstream infections are a major cause of morbidity and mortality, and identifying the causative organism(s) is critical. Can the most important step in this process really be as simple as collecting enough volume of blood for culture? Let’s discuss some of the evidence, and the role of the clinical microbiology laboratory in this important testing process.

Clinical microbiology tests are not performed to satisfy the curiosity, but to serve patients. While technical performance comparisons will sometimes suffice for test evaluation, health outcome studies may be superior for determining the true value of a diagnostic test.
