• Hybridization-based detection using DNA probes emerged as a core diagnostic paradigm, enabling sequence-specific screening across the late 1960s–1980s via membrane-filter assays, oligonucleotide probes, and DNA hybridization methods. [3], [6], [8], [16], [18], [19]

• Amplification-based diagnostics expanded capacity for direct disease detection and prenatal testing through enzymatic amplification, amplified DNA analyses, and HIV-1 DNA amplification from 1985–1988. [5], [14], [15]

• Prenatal diagnosis and genetic screening advanced through endonuclease mapping and analyses of linked DNA polymorphisms, enabling antenatal risk assessment and detection based on gene-linked markers. [11], [15], [19], [20]

• Allele-specific diagnostics and mutation-focused analyses for sickle cell and related β-globin disorders used targeted probes, amplification, and mutation detection to characterize diagnostic variants. [4], [5], [6], [7], [10]
