Question

Which statement correctly compares the sensitivity of conventional diagnosis and molecular diagnosis?

Options

• Conventional diagnosis has very high sensitivity and detects trace DNA/RNA.

• Both methods have low sensitivity and require visible symptoms.

• Conventional diagnosis has low sensitivity and needs a high pathogen load.

• Molecular diagnosis has low sensitivity and needs a high pathogen load.

Answer 1

Conventional diagnosis has low sensitivity because it needs a high pathogen load. Molecular diagnosis is very sensitive and can detect trace DNA/RNA.
