Chart tracking the time needed to report the status of a sample brought in for classical Bacillus anthracis testing at the New York Bioterrorism Response Laboratory. Negative samples with no suspicious growth could be reported in 24 hours. However, any samples with growth required some degree of subplating or culturing in brain heart infusion broth (BHIB), were heat shocked, and then tested. Reporting of final results on samples could take 3–4 days. SBA, sheep blood agar; CW, cell wall; CAP, capsule; DFA, direct fluorescent-antibody assay; PCR, polymerase chain reaction; Ph, phage; +, positive.
