Collect a TB sputum series for AFB

Practice the sequence you already learned for “Collect a TB sputum series for AFB” until the order feels automatic. Drill the CDC TB-diagnostic order from public-health nursing. Collect at least three specimens 8 to 24 hours apart with one early-morning sample; do not discard a first specimen that looks inadequate.

1. Instruct the patient outdoors or in a negative-pressure space.
2. Collect an early-morning sputum, not saliva.
3. Do not discard the first specimen because it looks inadequate.
4. Label at the bedside and leak-proof the container.
5. Repeat specimens 8 to 24 hours apart until at least three are collected, including one morning specimen.
6. Keep specimens refrigerated and send to the designated lab.
7. Do not delay treatment when TB is the presumptive diagnosis and specimens are already collected.
