PCR has high/low sensitivity & high/low specificity.

Explanation:
PCR detects a specific genetic sequence by amplifying it, which allows even tiny amounts of target material to be detected—this is high sensitivity. It also achieves high specificity because the primers and probes are designed to match only the target sequence, minimizing amplification of non-target material. Taken together, PCR offers both high sensitivity and high specificity. Note that in practice, contamination can compromise specificity and inhibitors can reduce sensitivity, but with proper technique and controls these issues are minimized. Therefore, the best answer is high sensitivity and high specificity.
