The device is a chemical test strip that provides semi-quantitative results based on color changes, not AI/ML analysis.
No
The device is used to monitor the proper preparation of dialysate solutions, not to treat a patient directly.
No
Explanation: The device monitors the proper preparation of dialysate solutions by testing their chemical concentrations (pH, bicarbonate, glucose) and is used to supplement current methods for testing dialysate. It does not provide information about a patient's health status or diagnose any medical condition in a patient.
No
The device description clearly states it is a "firm plastic strip" containing "three reagent areas," indicating a physical, hardware-based device.
Yes, this device is an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The device is intended to provide semi-quantitative indications of chemical concentrations (pH, bicarbonate, glucose) in a biological fluid (dialysate solution, which is used in a medical procedure involving the body).
- Device Description: It's a test strip with reagent areas designed to react with the sample.
- Performance Studies: The studies involve testing samples obtained from a dialysis clinic and intentionally misdiluted samples, which are relevant to the clinical use of the dialysate.
- Predicate Devices: The predicate devices listed include a test pad and a conductivity meter, both of which are typically used in a clinical or laboratory setting for testing biological or related solutions.
The definition of an IVD generally includes devices used to examine specimens derived from the human body to provide information for the diagnosis, treatment, or prevention of disease. While dialysate itself isn't directly derived from the human body, its composition is critical for a medical procedure performed on the human body (dialysis), and testing it falls under the scope of providing information for the proper execution of that treatment. The test strip is analyzing the chemical composition of a solution used in a medical treatment, making it an in vitro diagnostic device.

Intended Use / Indications for Use
The Serim Dialysate Monitor Test Strips provide semi- quantitative indications of pH, bicarbonate ion, and glucose in the final bicarbonate dialysate. SERIM™ Dialysate Monitor™ Test Strips determine whether dialysate concentrates for hemodialysis were diluted properly to give a final dialysate with the proper proportions of bicarbonate and acetic acid/glucose. Significant misdilutions of the acid concentrate will give rise to excessively high and low levels of pH, alkalinity, and glucose in the dialysate The test is intended to supplement current methods of dialysate testing.
The Serim™ Dialysate Monitor™ Test Strip provides semi-quantitative indications of pH, bicarbonate, and glucose (which acts as a tracer for the acid concentrate) concentrations in final bicarbonate dialysate solutions. They can be used to monitor the proper preparation of such dialysate solutions. The Serim™ Dialysate Monitor™ Test Strips are to be used to supplement current methods for testing dialysate.

Summary of Performance Studies
The performance of the SERIM Dialysate Monitor Test Strips was studied using samples obtained from a dialysis clinic. In addition, normal and intentionally misdiluted samples were prepared. Significantly misdiluted samples had intentional dilution errors of 2X or 0.5X the correct amount of bicarbonate concentrate. All normal samples gave the expected values as read by the test strips. Significantly misdiluted samples were readily detected by the strips and also provided indications of which component, acid or bicarbonate concentrate was added in the improper amount. We have shown that when solutions were misdiluted by 35% or more, there was a good probability of detecting this misdilution by means of the test strip. Each of the pads on the test strips was substantially equivalent to the results of the corresponding predicate devices.

§ 876.5820 Hemodialysis system and accessories.
(a)
Identification. A hemodialysis system and accessories is a device that is used as an artificial kidney system for the treatment of patients with renal failure or toxemic conditions and that consists of an extracorporeal blood system, a conventional dialyzer, a dialysate delivery system, and accessories. Blood from a patient flows through the tubing of the extracorporeal blood system and accessories to the blood compartment of the dialyzer, then returns through further tubing of the extracorporeal blood system to the patient. The dialyzer has two compartments that are separated by a semipermeable membrane. While the blood is in the blood compartment, undesirable substances in the blood pass through the semipermeable membrane into the dialysate in the dialysate compartment. The dialysate delivery system controls and monitors the dialysate circulating through the dialysate compartment of the dialyzer.(1) The extracorporeal blood system and accessories consists of tubing, pumps, pressure monitors, air foam or bubble detectors, and alarms to keep blood moving safely from the blood access device and accessories for hemodialysis (§ 876.5540) to the blood compartment of the dialyzer and back to the patient.
(2) The conventional dialyzer allows a transfer of water and solutes between the blood and the dialysate through the semipermeable membrane. The semipermeable membrane of the conventional dialyzer has a sufficiently low permeability to water that an ultrafiltration controller is not required to prevent excessive loss of water from the patient's blood. This conventional dialyzer does not include hemodialyzers with the disposable inserts (Kiil type) (§ 876.5830) or dialyzers of high permeability (§ 876.5860).
(3) The dialysate delivery system consists of mechanisms that monitor and control the temperature, conductivity, flow rate, and pressure of the dialysate and circulates dialysate through the dialysate compartment of the dialyzer. The dialysate delivery system includes the dialysate concentrate for hemodialysis (liquid or powder) and alarms to indicate abnormal dialysate conditions. This dialysate delivery system does not include the sorbent regenerated dialysate delivery system for hemodialysis (§ 876.5600), the dialysate delivery system of the peritoneal dialysis system and accessories (§ 876.5630), or the controlled dialysate delivery system of the high permeability hemodialysis system § 876.5860).
(4) Remote accessories to the hemodialysis system include the unpowered dialysis chair without a scale, the powered dialysis chair without a scale, the dialyzer holder set, dialysis tie gun and ties, and hemodialysis start/stop tray.
(b)
Classification. (1) Class II (performance standards) for hemodialysis systems and all accessories directly associated with the extracorporeal blood system and the dialysate delivery system.(2) Class I for other accessories of the hemodialysis system remote from the extracorporeal blood system and the dialysate delivery system, such as the unpowered dialysis chair, hemodialysis start/stop tray, dialyzer holder set, and dialysis tie gun and ties. The devices subject to this paragraph (b)(2) are exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 876.9.

acid incorporated into the test pad. This process will cause a change in the ratio of acid and salt form of the acid that in turn leads to a pH change in the buffer system. This pH change produces a visual change in the color of a pH indicator in the pad. This color change can be correlated with the concentration of bicarbonate originally present in the sample. The predicate device is a conductivity meter. These are routinely used in dialysis as a measurement of the conductivity of the final dialysate solution. We have specifically used as the predicate device, an IBP HDM97 conductivity meter, (510(k) number K020908).
Conductivity is a function of the concentration of all ionic material in the test solution and of the mobility of the individual ions, with hydrogen ion being especially mobile. As the concentration of bicarbonate in the final dialysate changes due to misdilution, the conductivity of the solution correlates with changing bicarbonate concentration. Therefore, we expect and we have found that the color of the test strip also correlates with bicarbonate concentration. Since both the conductivity and the test strip colors correlate with total ionic concentrations it was expected and was found experimentally that the test strips correlated well with the conductivity of the final dialysate assuming that the concentration of other ions remains about constant.
Generally, glucose (a.k.a. dextrose) is added routinely to dialysis solutions for all patients in quantities sufficient to insure that, when properly diluted, the resulting glucose concentration should be 200 mg/dl. (0.2%). The constant level of glucose in these solutions is included by the manufacturer with the acetic acid concentrate. Therefore, the glucose can act as a tracer for the acid concentrate.
The glucose test strip used in this test is similar in composition to the predicate device. It consists of glucose oxidase, peroxidase, buffers, and an indicator. We compared the performance of the Serim glucose test strip against the performance of the glucose pad on the Bayer MultiStix 10 SG test strip using standard glucose solutions prepared in dialysate. For simplicity, the glucose pad on the Bayer MultiStix 10 SG test strip will be referred to as the Bayer glucose strip. Each test strip separately correlated well with known glucose concentrations. Therefore, it was expected and found that the Serim test strip correlated well

| Conclusion: | These studies indicate that SERIM Dialysate Monitor Test Strips
can be used to monitor the proportioning of sodium bicarbonate,
acid concentrate and purified water to determine that the final mix
is appropriately prepared. These strips are to be used to
supplement current dialysate testing regimens. |
