The description details a standard turbidimetric immunoassay method and does not mention any AI or ML components.
No
This device is for in vitro diagnostic use, intended for the quantitative determination of albumin in human urine to aid in the diagnosis of kidney disease, not for direct therapeutic intervention.
Yes
The "Intended Use / Indications for Use" section explicitly states that the device aids in the diagnosis of kidney disease ("Measurement of albumin aids in the diagnosis of kidney disease.").
No
The device description clearly states it is a "ready to use reagent" and describes a chemical reaction (turbidimetric immunoassay) and measurement of absorbance, indicating a physical reagent and a chemistry analyzer are core components, not just software.
Yes, this device is an IVD (In Vitro Diagnostic).
Here's why:
- Explicit Statement: The "Intended Use / Indications for Use" section clearly states: "For In Vitro Diagnostic Use."
- Intended Use: The device is intended for the "quantitative determination of low level albumin in human urine." This is a laboratory test performed on a biological sample (urine) outside of the body to aid in diagnosis.
- Mechanism: The "Device Description" explains that it uses a "turbidimetric immunoassay (TIA)" which is a common in vitro diagnostic technique.
- Components: The description mentions a "Calibrator Set" and "Controls," which are standard components of IVD systems used for calibration and quality control of the assay.
All of these points align with the definition of an In Vitro Diagnostic device.

Device Description
Good Biotech Corp. 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.

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.
Summary of Performance Studies
Comparative performance studies were conducted on 50 urine samples.
The results summarized below:
| Comparative Method | Slope | Intercept (mg/L) | Correlation 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.
