TOOLS USED FOR IDENTIFYING AN INFECTION Flashcards
What is the primary purpose of a gallium scan?
To detect infections and inflammation in the body.
True or False: A left shift in white blood cell count indicates a response to infection.
True
What does a culture in microbiology help identify?
The specific microorganism causing an infection.

effectiveness
What imaging technique is typically used to visualize internal organs and detect infections?
CT scan
What is a common finding in a complete blood count (CBC) that indicates infection?
Increased white blood cell count.
What does the term ‘sensitivity’ refer to in microbiology?
The susceptibility of an organism to a specific antimicrobial agent.
True or False: A gallium scan can differentiate between bacterial and viral infections.
False
What type of white blood cell is primarily involved in combating bacterial infections?
Neutrophils
What does a CT scan use to create images of the body?
X-rays

deep-seated
What is the role of lymphocytes in infections?
To respond to viral infections and produce antibodies.
True or False: Cultures can be performed on blood, urine, and tissue samples.
True
What is the significance of elevated eosinophils in a blood test?
It may indicate allergic reactions or parasitic infections.

The presence of bacteria in the bloodstream.
What is the typical time frame for obtaining results from a culture?
24 to 48 hours
True or False: A left shift can be caused by stress and physical exertion.

What is the main advantage of a gallium scan over other imaging techniques?
It can provide functional information about inflammation.
