Performed on Specimens From
California local public health laboratories
Acceptable Sample/Specimen Type for Testing
Minimum Volume Required
Storage & Preservation of Sample/Specimen Prior to Shipping

Patient’s name, accession number, inoculation date or subculture date.

960. Drugs tested are amikacin 1.5 µg/ml, moxifloxacin 0.25 µg/ml, capreomycin
3µg/ml, and ethionamide 5µg/ml. If susceptible to moxifloxacin at 0.25 μg/ml,
this predicts susceptibility to levofloxacin as well. When resistant to
moxifloxacin at 0.25 µg/ml, testing moxifloxacin MIC at 0.5, 1, 2, and 3 μg/ml
is performed. If the initial testing shows ethionamide resistance, testing at 5
µg/ml and 10 µg/ml is performed.
Average 2 weeks
Interferences & Limitations
