Answer: 3. ELISA Technique

ELISA detects antigens or antibodies and can reveal infection (e.g. HIV) before symptoms appear, so it is the technique useful for early detection.

Southern blotting detects specific DNA and western blotting detects specific proteins, and plain hybridization is not a routine early-diagnosis test. Answer: ELISA.
