Midstream Urine: >100 x 10^6 cfu/L Staphylococcus saprophyticus – Shipped May 16, 2016

MAIN EDUCATIONAL POINTS from M161-1

  1. In routine diagnostic laboratories, novobiocin (5ug) is generally a distinguishing test used to base the identification of S. saprophyticus.
  2. An additional comment in reference to antibiotic testing and/or treatment in the reporting to assist the clinician on treatment would be helpful.
