The description focuses on automated laboratory processes and standard data analysis, with no mention of AI or ML terms or concepts.
No.
The COBAS TaqMan Analyzer is an in-vitro diagnostic (IVD) device used for detecting nucleic acids, not for directly treating or diagnosing patients.
Yes
The device is a "fully automated amplification and detection system for nucleic acids" and the performance studies mention "specificity" and "sensitivity," which are typical metrics for diagnostic devices.
No
The device description clearly outlines multiple hardware components including a thermal cycler module, robotic transfer unit, and photometer module, in addition to the workstation and processor. This indicates it is a physical instrument, not a software-only device.
Yes, this device is an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use explicitly states it's for "amplification and detection system for nucleic acids using 5' nuclease technology." This process is performed on biological samples in vitro (outside the body) to provide information about a patient's health status.
- Device Description: The description details a system that automates steps of the Polymerase Chain Reaction (PCR) process, which is a common technique used in IVD testing to detect and quantify nucleic acids (like DNA or RNA) from samples.
- Performance Studies: The performance studies describe evaluations of metrics like Linearity, Dynamic Range, Precision, Sensitivity, and Specificity. These are standard performance characteristics assessed for IVD devices to demonstrate their accuracy and reliability in detecting and measuring analytes in biological samples.
- Predicate Device: The mention of a predicate device (COBAS AMPLICOR Analyzer) with a K number (K964506) strongly indicates that this device is being compared to a previously cleared IVD device, a common practice in the regulatory pathway for IVDs.
The device is designed to analyze biological samples (implied by the mention of nucleic acids and the comparison to a device used for HCV testing) in vitro to provide diagnostic information. This aligns directly with the definition of an In Vitro Diagnostic device.

Device Description
The COBAS TaqMan Analyzer is a flexible, automated batch analyzer that automates the real-time kinetic amplification and detection steps of the Polymerase Chain Reaction (PCR) process. The COBAS TaqMan Analyzer combines the operations of automated handling of reaction tubes (K-Tubes), thermal cycling, controlled temperature incubation, real-time photometric detection at each cycle and result reporting into a single automated analyzer. The instrument consists of four major sub-components: (1) a thermal cycler module; (2) a robotic transfer unit; (3) a photometer module and (4) a workstation, which together with an on-board real-time processor controls and monitors the major components including system and run control, results calculation, and system diagnostic tests and provides the user interface.
Potentiality infectious specimens are prepared off-line by manual or automated sample preparation methods resulting in highly purified nucleic acids, The purified nucleic acids solutions are added to K-Tubes containing PCR amplification and detection reagents, prior to placing on the analyzer. After the K-Tubes are loaded on the COBAS TaqMan Analyzer, the robotic arm transfers the K-tubes to each of four K-Tube Carriers which are in turn moved to the thermal cyclers for amplification and detection. Once reagents are added and the K-Tubes closed they are never opened again. Detection is achieved using dual labeled fluorescent probes contained in the PCR reaction. Cleavage of these probes during amplification results in an increase in fluorescent signal. The intensity of this signal is proportional to the amount of infectious organisms present in the specimen and quantitative results are determined based on both target and internal quality standard (IQS).
Fluorescent data is collected for both the target and the IQS at each cycle of the PCR. The titer of the sample is calculated at the end of the PCR run. On completion of cycling the intact capped K-Tubes are automatically removed from the thermal cyclers and disposed of into the waste station.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
The COBAS TaqMan Analyzer was shown to be substantially equivalent to the COBAS AMPLICOR Analyzer in all non-clinical performance studies. The non-clinical performance studies were designed to evaluate the analyzer comparing it to the predicate device (COBAS AMPLICOR Analyzer). The studies included the following comparative evaluations: Linearity, Dynamic Range, Precision, Sensitivity, Specificity, Carryover and Correlation.
The COBAS TaqMan Analyzer demonstrated comparable linearity while showing an enhanced dynamic range over the COBAS AMPLICOR Analyzer. The dynamic range for the COBAS TaqMan Analyzer was enhanced by 3 orders of magnitude over the predicate device (50 - 2x10^7 IU's/mL).
The COBAS TagMan Analyzer has demonstrated an improved sensitivity and specificity over the COBAS AMPLICOR Analyzer. The lower limit of quantitation was determined to be 50 IU/mL for the COBAS TaqMan Analyzer. Specificity was calculated to be 96.87% (93/96 for tested EIA sero-negative specimens). Retesting of the three TaqMan HCV positive/EIA negative samples by a manual HCV AMPLICOR Test confirmed that at least two of the three EIA negative samples were HCV RNA positive yielding a recalculated specificity of 98.9% (93/94).
Key Metrics (Sensitivity, Specificity, PPV, NPV, etc.)
Sensitivity: Improved over COBAS AMPLICOR Analyzer.
Specificity: 96.87% (93/96 for tested EIA sero-negative specimens), recalculated to 98.9% (93/94) after retesting.
