Intended Use
The CSAE method is an in vitro diagnostic test for the quantitative measurement of cyclosporine A (CSA) in human whole blood on the Dimension Vista® system. Measurements of CSA are used as an aid in the management of heart, liver and kidney transplant patients.
Device Description
The Dimension Vista® CSAE Flex® reagent cartridge is a pre-packaged in-vitro diagnostic test method (assay) that is specifically designed to be used on the Dimension Vista® Integrated system, a floor model, fully automated microprocessor-controlled, integrated instrument system. The Dimension Vista® system was previously cleared with seven associated test methods (K051087). This Special 510(k) is submitted for a packaging modification to the Dimension® Cyclosporine Extended Range (CSAE) Flex® reagent cartridge (K052017), an in-vitro diagnostic device that has been cleared under the 510(k) process for use on Dimension® clinical chemistry systems. The packaging change is to allow use on the Dimension Vista® system. The modifications also include a change in method parameters (sample size and reagent volume) but the final concentration of sample/reagent ratio in test milieu remains the same. The reagents contained in the Dimension Vista® CSAE Flex® reagent cartridges are the same as those contained in the Dimension® CSAE Flex® reagent cartridges manyfactured for the Dimension® clinical chemistry systems, another family of Siemens analyzers. The packaging modification does not affect the intended use of the devices, nor does it alter the fundamental scientific technology of the device. The CSAE method uses an immunoassay technique in which free and CSA bound antibody-enzyme species are separated using magnetic particles. The CSAE Flex® reagent cartridge contains a pretreatment reagent, B-galactosidase-CSA antibody conjugate, CSA immobilized on chromium dioxide particles, chlorophenol red B-dgalactopyranoside (CPRG) substrate, and diluent to hydrate the tablets. To perform the CSAE assay, a sample cup containing the whole blood sample to be analyzed and a CSAE Flex® reagent cartridge are placed appropriately on the Dimension Vista® system. The Dimension Vista® system mixes and lyses the whole blood sample. The lysed sample is then mixed with the antibody conjugate reagent. The CSA present in the sample is bound by the CSA antibody conjugate reagent. Magnetic particles coated with cyclosporine A are added to bind free (unbound) antibody-enzyme conjugate. The reaction mixture is then separated magnetically. Following separation, the supernatant containing the CSA antibody-enzyme complex is transferred to a cuvette and mixed with the substrate. B-galactosidase catalyzes the hydrolysis of CPRG (chlorophenol red B-dgalactopyranoside) to produce CPR (chlorophenol red) that absorbs light maximally at 577mm. The change in absorbance at 577nm due to the formation of CPR is directly proportional to the amount of CSA in the patient's sample and is measured using a bichromatic (577, 700nm) rate technique.
More Information

No
The description focuses on the immunoassay technique and the instrument's automated processes, with no mention of AI or ML.

No
This device is an in vitro diagnostic test used for the quantitative measurement of cyclosporine A, which aids in the management of transplant patients. It does not directly provide therapy.

Yes

The device is described as an "in vitro diagnostic test" and its measurements are used as "an aid in the management of heart, liver and kidney transplant patients," clearly indicating its diagnostic purpose.

No

The device is an in vitro diagnostic test kit (reagent cartridge) used on a physical instrument system (Dimension Vista® system). It involves chemical reactions and physical separation steps, clearly indicating it is not software-only.

Yes, this device is an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The "Intended Use / Indications for Use" section explicitly states that the CSAE method is an in vitro diagnostic test. It is used for the quantitative measurement of cyclosporine A in human whole blood, which is a sample taken from the body.
  • Device Description: The "Device Description" section refers to the Dimension Vista® CSAE Flex® reagent cartridge as a pre-packaged in-vitro diagnostic test method (assay). It also mentions that the device has been cleared under the 510(k) process for use on Dimension® clinical chemistry systems, which are instruments used for in vitro diagnostic testing.
  • Predicate Device: The "Predicate Device(s)" section lists K052017, the Dimension® CSAE Flex® reagent cartridge, which is also described as an in-vitro diagnostic device in the "Device Description".

All of these points clearly indicate that the device is intended to be used outside of the body to examine specimens (in this case, whole blood) for diagnostic purposes.
