Overview

Identification

A herpes simplex virus nucleic acid-based assay for central nervous system infections is a qualitative in vitro diagnostic device intended for the detection and differentiation of HSV-1 and HSV-2 in cerebrospinal fluid (CSF) samples from patients suspected of Herpes Simplex Virus (HSV) infections of the central nervous system (CNS). This test is intended as an aid in the diagnosis of HSV-1 and HSV-2 infections of the CNS. Negative results do not preclude HSV-1 or HSV-2 infection and should not be used as the sole basis for treatment or other patient management decisions.

Special Controls

(b) Classification. Class II (special controls). The special controls for this device are:

*Classification.* Class II (special controls). The special controls for this device are:(1) Design verification and validation must include: (i) Detailed documentation for the device description, including the device components, ancillary reagents required but not provided, and a detailed explanation of the methodology, including primer design and selection. (ii) Detailed documentation from the following analytical and clinical performance studies: Analytical sensitivity (limit of detection), reactivity, inclusivity, precision, reproducibility, interference, cross reactivity, carryover, and cross contamination. Documentation must include reagent and sample stability recommendations. (iii) Detailed documentation from a clinical study. The study, performed on a study population consistent with the intended use population, must compare the device performance to the results of two polymerase chain reaction methods followed by bidirectional sequencing. (iv) Documentation of an appropriate end user device training program that will be offered as part of efforts to mitigate the risk of failure to correctly operate the instrument. (v) Quality assurance protocols and detailed documentation for device software, including standalone software applications and hardware-based devices that incorporate software. (2) The labeling required under § 809.10(b) of this chapter must include: (i) A detailed explanation of the interpretation of results and acceptance criteria. (ii) A limiting statement indicating that negative results do not preclude HSV-1 or HSV-2 infection and should not be used as the sole basis for treatment or other patient management decisions.
