Which of the following are nanoparticle probe technology assays used for blood cultures?

• A. BC-GP and BC-GN assays
• B. BC-GP assay only
• C. BC-GN assay only
• D. Neither BC-GP nor BC-GN assays

Answer: (A)

Nanoparticle probe technology in blood culture identification uses DNA probes attached to gold nanoparticles that hybridize to organism-specific sequences, producing a detectable signal on a microarray. This setup enables rapid, targeted identification directly from positive blood culture bottles. There are two parallel assays on the platform: one for Gram-positive organisms and one for Gram-negative organisms. Both assays are designed to identify a broad range of clinically important pathogens and some resistance markers, using the nanoparticle probe readout rather than conventional culture methods. Because the question asks which assays are nanoparticle probe technology assays used for blood cultures, both BC-GP and BC-GN fit, making the combined option the best choice.
