Question

question 23
a virus is identified by observing growth patterns on cultured media. what is this type of identification called?
qualitative
quantitative
definitive
presumptive

Explanation:

Analyze the identification method

Observing growth patterns or colony morphology on cultured media provides an initial, preliminary identification of a microorganism (such as a virus or bacteria) based on its physical characteristics.

Define the medical coding terminology

• Presumptive identification: Identification of a microorganism based on preliminary findings, such as growth patterns, colony morphology, or simple staining, without final confirmation.
• Definitive identification: Final, specific identification of a microorganism using detailed biochemical, molecular, or serological testing.
• Qualitative/Quantitative: Refer to the presence/absence or numerical measurement of an analyte, rather than the level of specificity in organism identification.

Determine the correct classification

Because observing growth patterns on cultured media is a preliminary observation rather than a final confirmatory test, it is classified as presumptive identification.

Answer:

• Qualitative
• Quantitative
• Definitive
• Presumptive (Correct answer)
