The sensitivity test evaluates which antibiotics or antifungal agents are effective against the isolated organism.

Clinical uses include:

Diagnosing septicemia (bloodstream infection).

Identifying the causative pathogen in febrile patients.

Guiding targeted antimicrobial therapy.

Monitoring patients with persistent fever, immunosuppression, or indwelling medical devices.

The test requires sterile collection of blood samples, usually from multiple sites, to reduce contamination risk.

Analyte: Microorganisms (bacteria/fungi) present in blood.

Normal Result: No growth (blood is sterile).

Abnormal Findings:

Positive culture: Indicates bloodstream infection.

Sensitivity profile: Shows which antibiotics/antifungals are effective or resistant.

Clinical Use:

Provides a definitive diagnosis of septicemia.

Helps select the most effective antimicrobial treatment.

Monitors treatment response and detects resistant organisms.
