How soon after antibiotic treatment is completed can a pt have cultures drawn?

What are rhe the chances of a false-negative when cultures are taken one day after treatment has begun?

How is important is the collection order of cultures?

You can draw cultures anytime after abx therapy has begun, you just have to draw ARDS as opposed to regular cultures. They have to be three days post antibiotics for regular cultures. May vary by facility, that's just how we roll at my hospital.

I was wondering something similar. If the ED gives a 2 L bolus of NS and broad-spectrum IV antibiotics 6-12 hours before the ICU inserts a foley catheter and sends urine cultures to lab, will the cultures be altered?
