Final answer:
A biopsy involves the removal of tissue for laboratory analysis to diagnose diseases like cancer. Culture and sensitivity tests identify pathogens and inform treatment, while dermatoscopy uses a dermatoscope to examine skin lesions for disorders such as melanoma.
Step-by-step explanation:
Definitions of Diagnostic Procedures
A biopsy is the surgical removal of a tissue specimen for medical laboratory analysis, usually to diagnose conditions such as cancer. During a culture and sensitivity (C&S) diagnostic procedure, microorganisms from a sample are grown in a lab to identify the type of bacteria or fungus causing an infection, and tests are run to determine the appropriate antibiotics that the organisms are sensitive to, aiming for an effective treatment. The procedure of excisional biopsy involves the complete removal of a lesion, often with a margin of normal tissue for comprehensive analysis, whereas an incisional biopsy involves removing only a portion of the abnormal tissue or lesion for examination. A dermatoscope is an instrument used for the examination of skin lesions, particularly to increase the accuracy of the diagnosis of melanoma. The process of examining the skin with a dermatoscope is referred to as dermoscopy.
