This figure illustrates the amplification curves of VZV target DNA sequences identified in standard positive controls (A and C) alongside the cerebrospinal fluid (CSF) of a patient (B), as determined through quantitative polymerase chain reaction (Q-PCR). The ΔRn represents the detected fluorescence signal, which correlates with the quantity of VZV DNA copies present in the samples. The visual data aids in understanding VZV detection in clinical settings, emphasizing the significance of Q-PCR in viral diagnostics.
