2. Sample size used for the test set and the data provenance
- Sample Size for Precision (Test Set): For the candidate device, N=25 for each of the three samples tested for within-day and day-to-day precision for BUN, Calcium, Creatinine, and Glucose.
- Sample Size for Accuracy/Linearity (Test Set): Not explicitly stated as a separate sample size for accuracy/linearity, but these tests typically use a series of patient samples and/or spiked samples. The "Method Comparison and Bias Estimation Using Patient Samples" (NCCLS EP9-A2) guideline was followed, indicating the use of patient samples.
- Data Provenance: The study used "Human Serum". The country of origin for the data is not specified in the provided text. It is a retrospective evaluation of the performance of the reagent set.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts
This is a chemical assay study for quantitative determination of analytes. The "ground truth" is established by the analytical method itself and comparison to a predicate device. There is no mention of human experts interpreting results to establish ground truth in the context of this study.
4. Adjudication method for the test set
Not applicable. This is a quantitative chemical assay comparison, not an imaging or qualitative diagnostic study requiring adjudication.
5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance
Not applicable. This is a study of an in vitro diagnostic reagent set, not an AI-assisted diagnostic tool involving human readers.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
Yes, a standalone performance study was done. The "Teco CX3 Reagent Set for SYNCHRON CX System" is a standalone diagnostic reagent set designed for use on an automated analyzer (Beckman CX3 System). Its performance (precision, linearity, accuracy) was evaluated independently of human interpretation of the results, beyond the standard operation of the analytical system.
7. The type of ground truth used
The ground truth is established by:
- Predicate Device Comparison: The candidate device's performance is compared against legally marketed predicate devices (Teco BUN Liquid, Teco Calcium Color, Teco Creatinine, and Teco Glucose Liquid Reagent).
- Analytical Standards: Linearity and accuracy are typically assessed against known concentrations of calibrators or reference materials.
- Statistical Analysis: Precision is measured through statistical analysis of replicate measurements.
8. The sample size for the training set
Not applicable. This is not a machine learning or AI algorithm, and therefore there is no "training set" in the conventional sense. The development of the reagent set would involve internal validation and formulation, but these are not referred to as a "training set."
9. How the ground truth for the training set was established
Not applicable, as there is no "training set" for this type of device. The formulation and quality control of the reagents during manufacturing would ensure their performance, but this is a different concept from establishing ground truth for a machine learning model.

Test Principle
BUN (Urea Nitrogen) is hydrolyzed by urease to produce ammonium and bicarbonate which resulted in the increase of solution conductivity which is directly proportional to the concentration of BUN present in the test.
Calcium reacts with Arsenazo to form an bluish-purple chromophore which is measured spectrophotometrically at 650 nm. A reagent blank reading is taken just prior to sample injection, and a final absorbance reading is taken 21 seconds later. The differential absorbance, corrected for the reagent blank, is directly proportional to the calcium concentration.
Creatinine from the sample combines with the reagent to produce a red color complex. Absorbance reading is taken at both 520nm and 560nm at 25.6 seconds after picking up sample. The differential absorbance has been shown to be a direct measure of the concentration of creatinine in the sample.
SYSNCHRON CX3 determines glucose concentration by an oxygen rate method using a glucose Oxygen electrode. The rate of oxygen depletion is proportional to the glucose concentration in the samples.

Device Name: Teco CX3 Reagent Set for SYNCHRON CX System
Indications For Use: Teco CX3 Reagent Set for SYNCHRON CX System is intended for the quantitative determination of BUN, Calcium, Creatinine and Glucose in serum on Beckman CX3 System.
BUN measurements are used in the diagnosis and treatment of certain renal and metabolic diseases.
Calcium measurements are used in the diagnosis and treatment of parathyroid diseases, a variety of bone diseases, chronic renal and tetany.
