Laboratory

Sent to Focus Technologies, San Juan Capistrano, CA, forwarded to National Jewish Health, Denver, CO.

Performed

Monday - Friday.
Results available within 3-8 days.

Reference Range

By report.

Test Methodology

High Performance Liquid Chromatography (HPLC).

Interpretation

Specimens collected within 15 minutes of the next antibiotic dose represent the trough levels. Specimens obtained within 15-30 minutes after the end of I.V. infusion or 45-60 minutes after an IM injection represent the peak levels.

Sulindac may interfere with this assay.

Clinical Utility

Streptomycin is a systemic aminoglycoside. It is used primarily as an antitubercular and is active against Mycobacterium tuberculosis and M. bovis. It is also considered the drug of choice for the treatment of infections caused by Francisella tularensis and Yersinia pestis, and is often used to treat Brucella infections. Because many other gram-negative bacilli are resistant, streptomycin is rarely used to treat those organisms.
