Bloodstream Infection Experience
Blood collection timing and specimen transportation
01< /strong>A blood culture may be collected in a suspicious patient with any of the following indications:
• Unexplained fever (>38°C) or hypothermia (<36°C), chills, low blood pressure, etc.
• Inflammatory response parameters such as C-reactive protein, procalcitonin (PCT), 1,3-glucan (G test) increased, etc.
02When bloodstream infection is suspected, when is the best time to get blood?
• If possible, take blood at the onset of chills or fever
• Blood before antibiotic treatment
• If antibiotics are already being treated, blood should be collected before the next dose Culture
03 How many blood samples should be taken?
• Adults should collect 2-3 sets each time, and each set should be collected from different puncture points. If infective endocarditis is suspected, multiple sets should be collected repeatedly.
• Adult “one set” blood culture refers to blood drawn from a puncture site and injected into one or more blood culture bottles (usually containing aerobic and anaerobic bottles)
• Multiple sets of blood cultures ensure sufficient blood collection and increase the positive rate
< p>• Single blood cultures are more difficult to interpret than multiple blood cultures
