Intended Use

Good Biotech Corp. (GBC) Microalbumin TIA system is intended to be used for the quantitative determination of low level albumin in human urine by turbidimetric immunoassay (TIA). Measurement of albumin aids in the diagnosis of kidney disease. GBC mAlb Calibrator Set 200 is intended to be used with GBC Microalbumin TIA for the quantitative determination of microalbumin in urine samples. GBC Microalbumin Controls are intended to be used as the assayed quality control material for the urinary albumin analysis. For In Vitro Diagnostic Use.

Device Story

System uses turbidimetric immunoassay (TIA) to measure low-level albumin in human urine. Input: urine sample mixed with duck anti-albumin antibody. Principle: antigen-antibody reaction causes agglutination, increasing sample turbidity. Output: absorbance change at 340 nm measured by general chemistry autoanalyzer; concentration determined via interpolation of calibration curve. Used in clinical laboratory settings by trained personnel. Results assist healthcare providers in diagnosing kidney disease.

Clinical Evidence

Bench testing only. Comparative performance study conducted on 50 urine samples comparing GBC Microalbumin TIA system against Randox Microalbumin Test kit and Wako Micro-Albumin B. Results demonstrated high correlation coefficients (0.997 and 0.998 respectively).

Technological Characteristics

Turbidimetric immunoassay (TIA) using duck anti-albumin antibody. Measures absorbance at 340 nm. Designed for use with general chemistry autoanalyzers. In vitro diagnostic reagent, calibrator, and control set.

Indications for Use

Indicated for quantitative determination of low-level albumin in human urine to aid in the diagnosis of kidney disease. For in vitro diagnostic use.

Regulatory Classification

Identification

An albumin immunological test system is a device that consists of the reagents used to measure by immunochemical techniques the albumin (a plasma protein) in serum and other body fluids. Measurement of albumin aids in the diagnosis of kidney and intestinal diseases.

Special Controls

*Classification.* Class II (special controls). The device is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to § 866.9.

Microalbumin TIA is a ready to use reagent for the quantitative determination of low level albumin in human urine by turbidimetric immunoassay (TIA). When microalbumin of the urine sample encounters with duck anti-albumin antibody, the agglutination based on the antigen-antibody reaction increases the turbidity of the sample. The value of the absorbance change at 340 nm is proportional to the albumin concentration of the sample and is recorded by a general chemistry autoanalyzer. Then, the actual microalbumin concentration of the urine sample is determined by interpolation of the calibration curve obtained by standard samples with known albumin concentrations. #### Intended Use #### Reagent: Good Biotech Corp. (GBC) Microalbumin TIA system is intended to be used for the quantitative determination of low level albumin in human urine by turbidimetric immunoassay (TIA). Measurement of albumin aids in the diagnosis of kidney disease. #### Calibrator: GBC mAlb Calibrator Set 200 is intended to be used with GBC Microalbumin TIA for the quantitative determination of microalbumin in urine samples. #### Control: GBC Microalbumin Controls are intended to be used as the assayed quality control material for the urinary albumin analysis. For In Vitro Diagnostic Use. #### Substantial Equivalence Comparative performance studies conducted on 50 urine samples yielded high correlation coefficients upon comparison of the GBC Microalbumin TIA system and the predicate devices, Randox Microalbumin Test kit and Wako Micro-Albumin B. The results are summarized below: {2}------------------------------------------------ | Comparative Method | Slope | Intercept<br>(mg/L) | Correlation<br>Coefficient | n | |----------------------|-------|---------------------|----------------------------|----| | Randox | 1.20 | -0.56 | 0.997 | 50 | | Wako Micro-Albumin B | 1.20 | -2.17 | 0.998 | 50 | #### Conclusion Good Biotech Corp. Microalbumin TIA system, calibrator set and controls are substantially equivalent to the predicate devices based on their intended purposes, design and the comparison performance results. {3}------------------------------------------------ Image /page/3/Picture/1 description: The image shows the logo for the U.S. Department of Health and Human Services.
