Final answer:
Blood culture specimens are drawn into a bottle with Tryptic Soy Broth (TSB) to facilitate the growth of microorganisms for further analysis and treatment design. Plastic disposable culture tubes are used for ease of handling, and after collection, blood samples may be processed to obtain plasma for additional testing.
Step-by-step explanation:
When conducting a blood culture, the specimens are drawn into a bottle with Tryptic Soy Broth (TSB). These bottles facilitate the growth of microorganisms present in the blood for identification and treatment. The use of plastic disposable culture tubes with caps aids in clean-up and disposal.
Furthermore, the blood collection method involves capillary action to draw blood into small diameter glass tubes. After collection, samples may be processed further, such as being mixed with anticoagulants like lithium heparin or K2EDTA and centrifuged to obtain plasma.
In some tests, particularly in bacteriological culture methods, a sterile swab may be used to collect a sample and introduced into sterile water or TSB, followed by incubation to allow potential pathogens to grow.
The medium in the bottle is called Tryptic Soy Broth (TSB). The use of plastic tubes with caps allows for easy cleanup and disposal, while the TSB provides a suitable environment for the growth of microorganisms in the blood sample.
