Blood sterility culture without antibiotic sensitivity determination (with biphasic medium)
Detects bacteria in blood and assesses sterility. Detects bacteremia early and confirms systemic infection.
Deviation mechanism: Bacteria may enter blood during various infectious processes. Culture using biphasic medium detects microorganisms even in small quantities, confirming sterility disruption.
Recommended for: sepsis or systemic infection symptom patients; prolonged fever of unknown origin; blood sterility monitoring in inpatient settings; bacteremia diagnosis clarification.
Venous blood in biphasic medium tubes
Preferably collect before antibiotic therapy
Avoid physical activity before collection
Maintain standard aseptic technique during blood collection
Prolonged fever of unknown origin; sepsis symptoms (chills, weakness, tachycardia); suspected blood bacterial infection; blood sterility monitoring during severe disease treatment.
Bacteria detected — bacteremia present; physician assesses clinical significance.
Not detected — blood sterile.
Physician makes final assessment.
Note: Sensitivity testing only when clinically significant organism detected.
Recommended physicians: Infectious disease specialist; General Practitioner; Pediatrician (children).
