No
The document describes a sample collection device and media, focusing on stabilization and inactivation of specimens. There is no mention of AI, ML, or any computational analysis of data. The performance studies are related to the physical and chemical properties of the media and its ability to preserve the sample for downstream molecular testing.
No
The device is intended for the collection, transport, and storage of specimens for molecular diagnostic tests, not for treating or diagnosing a disease.
No
The device is a collection media and extraction device intended for stabilizing, inactivating, collecting, transporting, and storing human specimens. It prepares specimens for use with "legally marketed molecular diagnostic tests," but it is not itself a diagnostic test.
No
The device description clearly outlines a physical collection tube with a stabilizing buffer and insert, indicating it is a hardware device for specimen collection and transport, not software.
Yes, this device is an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use explicitly states that the device is for the "stabilization and inactivation of upper respiratory and saliva human specimens suspected of containing SARS-CoV-2." It also mentions that specimens collected in the device are "suitable for use with legally marketed molecular diagnostic tests." This clearly indicates that the device is intended to be used in the process of diagnosing a disease (SARS-CoV-2) by analyzing a specimen taken from the human body.
- Device Description: The description details a collection tube pre-filled with a stabilizing buffer designed to prepare a human specimen for downstream diagnostic testing.
- Performance Studies: The performance studies described, such as Limit of Detection and Precision/Reproducibility, are typical analytical performance studies conducted for IVD devices to demonstrate their suitability for use in diagnostic workflows.
- Predicate Device: The predicate device listed (K202641; DNA/RNA Shield Collection Tube) is also a sample collection device intended for use with diagnostic tests, further supporting the classification of this device as an IVD.
In summary, the device is designed to collect, stabilize, and prepare human specimens for use with diagnostic tests, which is the core function of an In Vitro Diagnostic device.

Device Description
The iSWAB™-Respiratory Tract Sample Collection Media-Extraction Less (iSWAB™ -RC-EL) collection device consists of a collection tube that is pre-filled with 800 µL of the iSWAB™-RC-EL nontoxic, stabilizing buffer and fitted with a proprietary insert. The insert is designed to optimize the release of specimens collected with swabs into the stabilizing buffer, creating a minimal footprint and allowing for swab-free transport of specimens. The iSWAB™-RC-EL collection device eliminates the costly and timeconsuming RNA isolation step from diagnostic workflows.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
- Inactivation study: demonstrated inactivation of the SARS-CoV-2 virus.
- Limit of Detection study: An analytical sensitivity study was conducted to determine the Limit of Detection of SARS-CoV-2 collected in iSWAB™-Respiratory Tract Sample Collection Media-Extraction Less in combination with the BGI Real-Time Fluorescent RT-PCR Kit for Detecting SARS-CoV-2.
- Specimen Stability study: A stability study was conducted to demonstrate that SARS-CoV-2 is stabilized long-term at ambient temperature in iSWAB™-RC-EL.
- Precision/Reproducibility studies: Two reproducibility studies were conducted to evaluate Lot-Lot reproducibility, Day-Day, and Operator-Operator Reproducibility. The results of this study demonstrated lot-lot reproducibility.
- Compatibility study: Samples collected with iSWAB™- RC-EL (no RNA extraction steps required) are directly compatible with the CDC 2019-Novel Coronavirus (2019-nCoV) RT-PCR Diagnostic Panel (with TaqPath 1-Step Multiplex Master Mix, the BGI Real-Time Fluorescent RT-PCR Kit, Bio- Rad's Reliance SARS-CoV-2 RT-PCR Assay, the PRIME CovidDetect RT-LAMP-based assay, and the UCSD RT-LAMP and LFIA test for the detection of SARS-CoV-2. Compatibility is not limited to these assays.
- Sterilization & Shelf-life Testing: This device is non-sterile. The shelf life for the iSWAB-Respiratory Tract Sample Collection Media-Extraction Less Collection tube with media is 15 months after the date of manufacture. The iSWAB-Respiratory Tract Sample Collection Media-Extraction Less Collection tube with media was performed using Realtime and Accelerated stability on a total of 3 lots. Stability looked for bacterial and fungal growth in the media along with properties of the media, appearance, pH, voltage resistance and density.
- No animal studies were required.
- No human clinical performance testing was required.
