That’s not entirely true. Turn around time for “Rapid sputum test (aka) nucleic acid amplification tests (NAATs).”; done in three consecutive days, is 24 hours. If rapid sputum tests came back positive, you’re put on a treatment plan immediately without having to wait 2 months.
If NAATs came back negative, then sputum “culture” tests are performed and it can take 1 to 8 weeks.
Rapid sputum tests can tell if a person has TB within 24 hours. A test may be done when:
- A person is thought to have TB, but confirmation is needed before sputum culture results will be ready.
- A person may be infected with bacteria other than TB bacteria.
- A person who may have TB has been close to other people who will need treatment if they have been exposed.
