1. direct fluorescent antibody tests

indicate the presence of complement.
indicate the presence of an antibody.
can diagnose infection.
all of the above.

Explanation:

Question 1

Sampling methods vary; not all require anaerobic storage (e.g., aerobic samples). Aseptic technique is common but not all need anaerobic containers, so the statement is false.

In infectious disease sampling, acute samples are early in infection, convalescent are later from the same subject. This matches the definition, so the statement is true.

Direct fluorescent antibody tests use fluorescent - labeled antibodies to detect antigens (e.g., pathogens), aiding infection diagnosis. They don't indicate complement (complement detection is different) or just antibody presence (they detect antigens via antibody binding). So "can diagnose infection" is correct.

Answer:

b) False
