(a)Identification. A device that detects nucleic acid sequences from microorganisms associated with vaginitis and bacterial vaginosis is a qualitative in vitro diagnostic device intended for the detection of microbial nucleic acid sequences in vaginal specimens collected from patients with signs and symptoms of vaginitis or bacterial vaginosis. This device is intended to aid in the diagnosis of vaginitis or bacterial vaginosis when used in conjunction with clinical signs and symptoms and other laboratory findings.
(b)Classification. Class II (special controls). The special controls for this device are:
(1)Design verification and validation must include:
(i)Documentation with a detailed device description of device components; ancillary reagents required but not provided; and explanation of the methodology including primer/probe sequence, design, and rationale for sequence selection.
(ii)Documentation with information that demonstrates the performance characteristics of the device, including:
(A)Limit of Detection;
(B)Precision (reproductivity);
(C)Analytical specificity;
(D)Analytical reactivity (inclusivity);
(E)Specimen stability; and
(F)Effects of interfering substances.
(iii)Detailed documentation from a prospective clinical study. As appropriate to the intended use, the prospective clinical study must be performed on an appropriate study population, including women of various ages and ethnicities. The prospective clinical study must compare the device performance to results obtained from well-accepted comparator methods.
(iv)Detailed documentation for device software, including 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)For devices with an intended use that includes detection of nucleic acid sequences from bacteria associated with bacterial vaginosis, clinical performance stratified by patient demographics such as race, ethnicity, age, and pregnancy status.
(iii)For devices with an intended use that includes detection of nucleic acid sequences from bacteria associated with bacterial vaginosis, a summary of device results in an asymptomatic population with demographic characteristics appropriate to the intended use population.
(iv)For devices with an intended use that includes detection of either Candida species or bacteria associated with bacterial vaginosis, a limitation that Candida species and bacterial compositions associated with bacterial vaginosis can be present as part of normal vaginal flora and results should be considered in conjunction with available clinical information.
