Bacterial Culture, Aerobic, Urine
Method Description Describes how the test is performed and provides a method-specific reference
The urine specimen is inoculated onto sheep blood agar and eosin methylene blue agar using a calibrated loop. Following 18 to 24 hours of incubation, semiquantitative colony counts are determined and potential urinary pathogens are identified. Cultures with <10,000 cfu/mL of a single species are reported as "Organism present <10,000 cfu/mL." The presence of commensal flora of the urethra (contaminants) and mixed cultures of organisms present in colony counts <10,000 cfu/mL are reported as "mixed flora."(Koneman EW, Allen SD, Janda WM, et al: Color Atlas and Textbook of Diagnostic Microbiology.

Day(s) and Time(s) Test Performed Outlines the days and times the test is performed. This field reflects the day and time the sample must be in the testing laboratory to begin the testing process and includes any specimen preparation and processing time required before the test is performed. Some tests are listed as continuously performed, which means assays are performed several times during the day.
Monday through Sunday; Continuously
Analytic Time Defines the amount of time it takes the laboratory to setup and perform the test. This is defined in number of days. The shortest interval of time expressed is "same day/1 day," which means the results may be available the same day that the sample is received in the testing laboratory. One day means results are available 1 day after the sample is received in the laboratory.
Maximum Laboratory Time Defines the maximum time from specimen receipt at Mayo Medical Laboratories until the release of the test result
Specimen Retention Time Outlines the length of time after testing that a specimen is kept in the laboratory before it is discarded
Performing Laboratory Location The location of the laboratory that performs the test
