• To highlight the need for sensitive, non-radioactive detection systems for routine use.
• To discuss applications in infectious disease detection and inherited metabolic disorders.

Main Methods:

• Assaying for definite nucleic acid sequences using nucleic acid probes.
• Utilizing the inherent specificity and binding affinity of hybridization.
• Exploring the transition from radioactive to non-radioactive detection systems.

Main Results:

• Nucleic acid hybridization demonstrates high specificity in identifying target sequences.
• The method is applicable to detecting viral and bacterial genomes.
• Potential exists for diagnosing inborn errors of metabolism.

Conclusions:

• Nucleic acid hybridization is a valuable tool for laboratory diagnosis.
• Further development of non-radioactive detection is essential for broader adoption.
