The Sentosa® SA201 HSV-1/2 PCR Test is a real-time PCR-based qualitative in vitro diagnostic test for detection and differentiation of Herpes Simplex Virus (HSV-1 and HSV-2) DNA from male and female skin lesions from anogenital or oral sites. The test is intended for use as an aid in diagnosis of herpes infection in symptomatic patients.
Warning: The Sentosa® SA201 HSV-1/2 PCR Test is not FDA cleared for use with cerebrospinal fluid (CSF). The test is not intended to be used for prenatal screening.
The Sentosa® SA201 HSV-1/2 PCR Test is a (4x24) configuration contains reagents and enzymes for specific amplification of a 104 bp (base-pair) fragment of the UL30 gene common to both HSV1 and HSV2, and specific probes for the direct detection and differentiation of HSV1 and HSV2 amplicons, respectively. Pathogen detection by PCR is based on the amplification of specific regions of the pathogen genome. In real-time PCR, the amplified product is detected via fluorescent dyes, which are usually linked to oligonucleotide probes that bind specifically to the target sequences. Real-time monitoring of the fluorescence intensities during a PCR run allows the detection of the accumulating product. Amplification of the targets occurs in three channels: green, orange and red on the Sentosa® SA201. Output is recorded as the increase of fluorescence over time in comparison to background signal. Monitoring the fluorescence intensities during the PCR run allows the detection of the accumulating product without having to re-open the reaction tubes after the PCR run.
The Sentosa® SA201 HSV-1/2 PCR Test workflow starts with extraction of nucleic acids from samples (anogenital or oral swabs) using the Sentosa® SX Virus Total Nucleic Acid Kit on the Sentosa SX101 instrument. Following extraction, the instrument will automatically set up the PCR with the extracted nucleic acids in a 96-well PCR plate. Subsequently, the 96-well PCR plate is sealed and transferred to the Sentosa® SA201 for PCR amplification, followed by data analysis.
The Sentosa® Link facilitates data transfer between the Sentosa® SX101, the Sentosa® SA201 Reporter and existing LIS/LIMS (laboratory information systems) in the clinical lab. The Sentosa SX101 instrument communicates with Sentosa® SA201 thermocycler. This creates a user environment that links the SX101 and the Sentosa® SA201 to facilitate automated workflow to export results in a LIS/LIMS-compatible format.
The provided document describes the analytical and clinical performance of the Sentosa SA201 HSV-1/2 PCR Test, a qualitative in vitro diagnostic test for the detection and differentiation of Herpes Simplex Virus (HSV-1 and HSV-2) DNA. It is not an AI/ML-based device. Therefore, the questions related to AI/ML specific aspects (e.g., number of experts, adjudication, MRMC study, training set, ground truth for training set) are not applicable. The information focuses on the device's ability to accurately detect and differentiate HSV-1 and HSV-2 DNA in patient samples.
Here's an analysis of the provided information, focusing on the device's acceptance criteria and the studies proving it meets them:
1. Table of Acceptance Criteria and Reported Device Performance
The document does not explicitly state "acceptance criteria" in a single table, but the performance studies demonstrate implied criteria. For diagnostic devices like this, the key performance metrics are sensitivity, specificity, limit of detection (LoD), precision, and freedom from interference.
Study/Performance Metric | Implied Acceptance Criterion | Reported Device Performance |
---|---|---|
Limit of Detection (LoD) | LoD should be low enough for clinical utility (e.g., detected with ≥95% probability). | HSV-1 MacIntyre & KOS: 40 TCID50/mL (detected with 95% probability). |
HSV-2 MS & G: 4 TCID50/mL (detected with 95% probability). | ||
Precision | Consistent results across runs, operators, and instruments (e.g., agreement 100%, %CV |
