A glucose test system is a device intended to measure glucose quantitatively in blood and other body fluids.
Indications for Use
Glucose measurements are used in the diagnosis and treatment of carbohydrate metabolism disorders including diabetes mellitus, neonatal hypoglycemia, and idiopathic hypoglycemia, and of pancreatic islet cell tumors..
Specific Performance Characteristics
PreClinical/Laboratory/In Vitro Studies
The following eight performance characteristics (#1 Method Comparison - #8 Expected Values) should be included in the submission. Data should be provided that supports the use of the device with the specimen type(s) that are claimed to be appropriate for analysis:
- Method Comparison
-range of samples tested
- standard error of the estimate
-bias and bias plot
-number of samples tested
-plot of the data
-within-run (assay, and
-between-run (assay), or
-mean(s), standard deviation (s), and coefficient(s) of variation
-recovery, dilution, etc.
-minimum detection limit, or
-endogenous, e.g., bilirubin, hemoglobin, lipids, etc.
-exogenous, e.g., drugs, anticoagulants, etc.
- Stability Summary
-quality control interval
-quality control materials
- Expected Values
-literature reference (s), reference interval, or
-population study, reference interval,
-medical decision point(s) and/or
-critical decision point(s)
- Method Comparison
A method comparison study as described above, comparing performance with that of the predicate device as well as an appropriate reference method should be conducted to demonstrate substantial equivalence. A statistically significant sample of patients from a population representing the proposed intended use should be included in the study, spanning the appropriate assay range.
Total Measurement Error at selected decision points should be calculated and reported.
Refer to 21 CFR 809.10.
Other: For a multi-purpose instrument used for diagnostic purposes refer to 21 CFR 809.10 (b) (1),(2),(6),(14),and (15).
Instructions: Use this checklist for premarket notification for Chloride Test System as a guide in preparing your submission.
