| Prerequisite | Type | Confidence | Evidence level | Note | Sources |
|---|---|---|---|---|---|
| PCR (Polymerase Chain Reaction) (pcr_polymerase_chain_reaction) | required | 95% | primary_source | PCR diagnostics are defined by nucleic-acid amplification using PCR; the 1985 beta-globin diagnostic paper demonstrates the dependency directly. |
|
| DNA Sequencing (dna_sequencing) | enabling | 68% | expert_inference | Sequence information supports target, primer, and probe design for PCR diagnostics, but the diagnostic readout can be amplification rather than sequencing. |
|
| Clinical Laboratory Automation (clinical_laboratory_automation) | enabling | 68% | expert_inference | Clinical Laboratory Automation provides a capability that enables this technology without being the only possible path. |
