Question: 1 / 400

How much blood is needed for an infant's blood culture?

0.5 ml

1 ml

For an infant's blood culture, typically 1 ml of blood is needed. This amount is sufficient to allow for the necessary laboratory testing to identify any potential infections or diseases present in the bloodstream. It is important to collect an appropriate amount of blood to ensure the accuracy of the test results while minimizing discomfort for the infant.

Option A (0.5 ml), Option C (2 ml), and Option D (3 ml) are not the standard or recommended amounts for an infant's blood culture. Collecting too little blood (0.5 ml) may not provide enough sample for testing, while collecting more blood than necessary (2 ml or 3 ml) can be unnecessarily invasive and uncomfortable for the infant. Therefore, the correct and most appropriate amount of blood needed for an infant's blood culture is 1 ml.
