Bacterial Culture, Blood
Method Description Describes how the test is performed and provides a method-specific reference
The skin surface should be decontaminated with tincture of iodine prior to venipuncture to reduce the chances of introducing contaminating organisms from the skin. Blood is collected and divided among aerobic and anaerobic bottles. The bottles are incubated at 35 degrees C for 5 days. Positive bottles are gram stained, subcultured and microorganisms recovered are identified by conventional techniques.(Baron EJ, Weinstein MP, Dunne WM Jr, et al: Blood cultures IV. In Cumitech 1C.

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.
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
Negative bottles - until reported; positive bottles are retained for 3 weeks
Performing Laboratory Location The location of the laboratory that performs the test
