Abstract
None:
Polymerase chain reaction (PCR) plays a central role in parasite diagnostics but is increasingly interpreted as a general test for parasitic infection. Because parasites lack shared molecular features amenable to universal assays, PCR is inherently primer bounded and hypothesis confirming. This article clarifies the interpretive limits of PCR and argues for aligning diagnostic claims with parasite biology.
