{0}------------------------------------------------ K023268 NOV 1 5 2002 #### 510 (k) Summary ### pHoenix ISE Standards for Roche AVL Systems AVL was the original manufacturer of the AVL Systems. Recently Roche Diagnostics acquired AVL and these Chemistry Systems are now referred to as Roche AVL Systems. pHoenix Diagnostics, Inc. is submitting a 510 (k) notification for Standard A. B. and C for the Roche AVL Systems for the quantitative determination of Na+, K+, Cl-, Ca+ and Li+ in human serum. These Standards are used for the calibration of the Roche AVL Systems. pHoenix Diagnostics, Inc. is claiming substantial equivalence to predicate devices manufactured by Roche/AVL Diagnostics. The products encompassed by this 510 (k) submission are Class II (75 JIX) In Vitro Diagnostic Solutions manufactured by pHoenix Diagnostics, Inc., 8 Tech Circle, Natick, MA 01760. These pHoenix ISE Standards are intended to serve as direct replacements to like named products manufactured by Roche Diagnostics. | pHoenix<br>Cat.# | Roche<br>Diagnostics Cat. # | Description and<br>Utilities | Analytes and Concentrations | | | | | | | |------------------|-----------------------------|-------------------------------------|-----------------------------|-----|-------|------|-----|-----|------| | | | | Na | K | Cl | Ca | Li | CO2 | pH | | 4-001 | BP0936 | Standard A for<br>AVL 982,983,985 | 150 | 5 | 115 | 0.9 | 0.3 | / | / | | 4-009 | BP0937 | Standard B for<br>AVL 985 | 100 | 1.8 | 72 | 1.5 | 0.3 | / | / | | 4-010 | BP0938 | Standard C for<br>AVL 985 | 150 | 5 | 115 | 0.9 | 1.4 | / | / | | 4-005 | BP0442 | Standard B for<br>AVL 982, 983 | 50 | 1.8 | 59.8 | 4 | / | / | / | | 4-006 | BP1232 | Standard A for<br>AVL 984, 987, 988 | 150 | 5 | / | 1.25 | / | / | 7.38 | | 4-007 | BP1218 | Standard B for<br>AVL 984, 987, 988 | 100 | 1.8 | / | 2.5 | / | / | 6.84 | | 4-011 | BP1203 | Standard A for<br>AVL 986 | 150 | 5 | 125.3 | / | / | 25 | / | | 4-012 | BP1201 | Standard B for<br>AVL 986 | 80 | 1.8 | 70.9 | / | / | 10 | / | Listed below are pHoenix products, their Roche Diagnostics equivalents and usages on the Roche AVL instruments: {1}------------------------------------------------ ### 510 (k) Summary cont. pHoenix Diagnostics uses a similar composition and design as that used by Roche Diagnostics in its products. pHoenix has shown performance equivalence of its products to Roche Diagnostics products in the following manner: - . Through a method comparison where results obtained on Roche AVL Systems calibrated with pHoenix products and compared with results obtained on the same analyzer calibrated with Roche Diagnostics products; and - Through a precision study where pHoenix products were installed on Roche AVL . systems and samples were measured over 20 runs. A summary of the results of these studies is as follows: Precision data was collected from the analysis of 2 levels of serum controls measured 2 runs per day, 2 times per run for 20 days on Roche AVL Systems for different electrolytes installed with pHoenix reagents. The NCCLS Guideline for precision evaluation, EP5-T, was followed. Typical Results are as follows: ## AVL 983 | Analyte | Level | N | Mean | STD | CV% | Min | Max | |---------|-------|----|------|------|------|-----|-----| | Na | 1 | 80 | 124 | 1.52 | 1.2 | 121 | 127 | | Na | 3 | 80 | 164 | 2.6 | 1.6 | 162 | 166 | | K | 1 | 80 | 1.93 | 0.11 | 5.5 | 1.7 | 2.2 | | K | 3 | 80 | 6.5 | 0.06 | 0.96 | 6.4 | 6.6 | | Cl | 1 | 80 | 85.6 | 1.4 | 1.7 | 82 | 89 | | Cl | 3 | 80 | 148 | 0.82 | 0.56 | 146 | 149 | #### AVL 984 | Analyte | Level | N | Mean | STD | CV% | Min | Max | |---------|-------|----|------|-------|------|------|------| | Na | 1 | 80 | 124 | 1.48 | 1.2 | 121 | 127 | | Na | 3 | 80 | 165 | 1.75 | 1.06 | 162 | 170 | | K | 1 | 80 | 1.91 | 0.105 | 5.5 | 1.7 | 2.2 | | K | 3 | 80 | 6.7 | 0.101 | 1.52 | 6.4 | 6.8 | | Ca | 1 | 80 | 2.36 | 0.112 | 4.76 | 2.2 | 2.6 | | Ca | 3 | 80 | 0.84 | 0.014 | 1.69 | 0.81 | 0.87 | {2}------------------------------------------------ ### 510 (k) Summary cont. | △<br>1<br>1 | VL | તે જેવી સવલતો પ્રાપ્ય થયેલી છે. આ ગામનાં પ્રાથમિક શાળા, પંચાયતઘર, આંગણવાડી તેમ જ દૂધની ડેરી જેવી સવલતો પ્રાપ્ય થયેલી છે. આ ગામનાં પ્રાથમિક શાળા, આંગણવાડી તેમ જ દૂધની ડેરી જે | |-------------|----|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | | | | | Analyte | Level | N | Mean | STD | CV% | Min | Max | |---------|-------|----|------|-------|------|-----|-----| | Na | 1 | 80 | 123 | 1.33 | 1.1 | 121 | 126 | | Na | 3 | 80 | 165 | 1.73 | 1.05 | 162 | 170 | | K | 1 | 80 | 1.84 | 0.08 | 4.43 | 1.7 | 2 | | K | 3 | 80 | 6.6 | 0.12 | 1.85 | 6.4 | 6.8 | | Li | 1 | 80 | 1.75 | 0.087 | 5 | 1.6 | 1.9 | | Li | 3 | 80 | 2.56 | 0.1 | 3.71 | 2.4 | 2.8 | #### Correlation with Roche AVL Reagents Correlation data was collected from 50 samples (patient serum samples, control samples and spiked samples) for Na*, K*, Cl*, Ca* and Li* measured on Roche AVL Systems installed with pHoenix reagents as compared with Roche Diagnostics reagents separately.
