This is the foundational, trusted method for diagnosing serious bloodstream infections caused by 'anaerobic' bacteria—germs that grow without oxygen. These can cause severe, deep-seated infections. Your blood sample is collected in a specialized, oxygen-free bottle and is incubated in our lab. It is then personally monitored by our expert microbiologists for any sign of growth. This conventional, hands-on technique is a reliable and proven gold standard. It is an essential part of a comprehensive sepsis workup, providing the definitive information your doctor needs to find and fight these specific, hard-to-treat pathogens.
