Droplet Digital Pcr System

Page Type
Product Code
Definition
A droplet digital PCR system is an in vitro diagnostic amplification and detection test system that is intended for the amplification, detection (qualitative and quantitative), and analysis of nucleic acid samples, isolated from clinical specimens, which have been partitioned into nanoliter or smaller droplets using a water oil emulsion technique. A droplet digital PCR system is intended for use with cleared or approved in vitro diagnostic assays which specify its use.
Physical State
The system may consist of separate components used for specific purposes (e.g., droplet generator and droplet reader), associated software, and consumables. Should not include real-time thermocyclers or massively parallel or high-throughput sequencers or instruments with analyzers for fluorescence.
Technical Method
The nucleic acid molecules partitioned into the individual droplets are amplified using real-time PCR methods, labeled with fluorescently labeled probes or other fluorescent labeling means, and the result of each droplet reaction is counted and quantified. The fluorescence is detect using a high-power light-emitting diode (LED). Fluorescence emission is detected through the use of filters on a photodiode. The emission filters are optimized for use with specific fluorescent dyes.

CFR § 862.2570 Instrumentation for clinical multiplex test systems

§ 862.2570 Instrumentation for clinical multiplex test systems.

(a) Identification. Instrumentation for clinical multiplex test systems is a device intended to measure and sort multiple signals generated by an assay from a clinical sample. This instrumentation is used with a specific assay to measure multiple similar analytes that establish a single indicator to aid in diagnosis. Such instrumentation may be compatible with more than one specific assay. The device includes a signal reader unit, and may also integrate reagent handling, hybridization, washing, dedicated instrument control, and other hardware components, as well as raw data storage mechanisms, data acquisition software, and software to process detected signals.

(b) Classification. Class II (special controls). The device is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 862.9. The special control is FDA's guidance document entitled “Class II Special Controls Guidance Document: Instrumentation for Clinical Multiplex Test Systems.” See § 862.1(d) for the availability of this guidance document.
