Final answer:
The laboratory diagnosis of S. pyogenes can be made by culturing throat or nasal specimens, performing an ASO procedure, or conducting an Anti-DNase B test, so the correct answer is 'All of the above'.
Step-by-step explanation:
The laboratory diagnosis of S. pyogenes, the bacterium responsible for causing conditions like strep throat and skin infections, can be established by various methods. Specifically, the correct answer to the question is D. All of the above, meaning that diagnosis can be made by:
- A. Culturing of throat or nasal specimens,
- B. ASO procedure (Antistreptolysin O titer), which detects antibodies against the streptolysin O produced by S. pyogenes,
- C. Anti-DNase B (ADN-B), another antibody detection test for antibodies against the DNase produced by this bacterium.
These methods help detect the presence or past presence of S. pyogenes infection.
