The summary describes an automated microscopic system for image capture, storage, and display, but does not mention any AI or ML algorithms for image analysis, classification, or interpretation. The technologist is responsible for reviewing and quantifying the results.
No
The device is described as a laboratory instrument for in vitro diagnostic use, intended to aid technologists in reporting urine microscopic results. It does not exert any direct therapeutic effect on a patient.
Yes
The device is described as "For In Vitro Diagnostic Use" and aids technologists in performing Urine Sediment Analysis, which is a diagnostic procedure. It helps in reporting a urine microscopic result, implying a role in diagnosis.
No
The device is described as a "laboratory instrument" and an "automated microscopic system" that "locates formed elements," "captures a minimum of 40 microscopic images," and "digitizes the images." This clearly indicates the presence of hardware components beyond 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".
- Purpose: The device is a laboratory instrument used for analyzing urine sediments from a urine slide. This analysis is performed in vitro (outside the living body) on a biological specimen to provide information for a medical diagnosis or to monitor a medical condition.
- Output: The output of the device (digital images of urine sediment constituents) is used by a qualified individual to report a urine microscopic result, which is a key component of a diagnostic process.
- Comparison to Manual Method: The device description explicitly states that the process is "substantially equivalent to the manual microscopic process," which is a standard IVD procedure.
- Performance Studies: The provided information includes details about performance studies (Precision, Reproducibility, Linearity, Correlation) which are typical evaluations for IVD devices to demonstrate their analytical performance.
All these points strongly indicate that the MICRO21 with Urine Sediment Analysis is intended and used as an In Vitro Diagnostic device.

Device Description
The MICRO21 with Urine Sediment Analysis, is an automated microscopic system that locates formed elements of wine sediment, digital stores images of the constituents and displays the images in an organized manner to aid technologists in performing an Urine Sediment Analysis procedure. The MICRO21 process is substantially equivalent to the manual microscopic process.
A summary of the MICRO21 with Urine Sediment Analysis process is as follows:
- Patient urine samples are prepared by a technologist pouring off 12mL of fresh urine into a centrifyge tube and capping 1. the tube.
-
- Each capped tube is then centrifuged at a relative centrifugal force of 400 for 5 minutes; approximately 1500 revolutions per minute with a 6 inch rotor radius (NCCLS Protocol GP 16-A).
-
- The tubes are then removed from the centrifyge without disturbing the sediment, uncapped and decanted to 1mL.
- After resuspending the sediment, 20 ul of commercial urine sediment stain (Sternheimer-Malbin) are added to the 4. sediment and mixed. Herein referred to as Stained Sample.
- One drop of the stained sample is placed into the designated well of the urine slide can hold up to 8 ર. individual stained samples.
-
- The technologist then enters the test order into the MCRO21 Review station Order Entry Screen, prints a barcode and places it on the urine slide. The barcode corresponds to the urine slide and wells allocated for the individual samples.
-
- The MCRO21 captures a minimum of 40 microscopic images, 16 at 100x magnification, 16 images at 200x magnification, and 8 images at 400x magnification, digitizes the images and stores them for display on a color monitor for review by a technologist.
- The technologist reviews the images and quantifies the results. 8.
- A report of the results for each patient is printed. 9.

182 stained samples were analyzed both manually and on the MICRO21 by three certified medical technologists. To generate a wider range of urinary constituents, 31 stained samples were created using serial dilution and enrichment. Using blinded experimental methods, the stained samples were reviewed manually, and processed by the MCRO21 and resultant images reviewed by the technologists.

Effectiveness Testing
To demonstrate the validity of the procedure, performance testing was conducted to assess the instrument's precision, accuracy, linearity, and correlation with the manual method. A summary of each is presented.
Test Method 1: Precision
To confirm instrument precision, a stained specimen sample from one processed and reviewed 5 times on the 10 commin there specimens, one each from a low, normal and high range were tested. The results were reviewed and recorded for each samples.
Test Method 2: Reproducibility
To confirm linearity, specimens containing reportable ranges for RBC's and squamous epithelial cells were processed and reviewed on the MICRO21. RBC and WBC were recorded at 200x magnification. Squamous epithelial cells were recorded at 100x magnification. Selected highly concentrated specimens were used and dilutions of the specimen were made to obtain ranges. The results were reviewed and recorded for each sample.
Test Method 3: Linearity
To confirm linearity, specimens containing reportable ranges for RBC's and squamous epithelial cells were processed and reviewed on the MICRO21. The results were reviewed and recorded for each sample.
Test Method 4: Correlation
The MICRO21 with Urine Sediment Analysis results were compared to the manual urine microscopic reference method using standard correlation statistics. Results are reported as number of formed elements per reportable range, as recommended by NCCLS in GP16-A, Urinalysis and Collection, Transportation of Urine Specimens, Approved Guideline. For quantitative results, the average value from each range was used for computing the regression analysis values. For quantitative items. R values were used to demonstrate correlation. For qualitative results, correlation or equivalence was determined to be within one reporting range of each other, as recommended in NCCLS GP16-A, section 2.3.2 Microsopic Urinalysis.
There were 182 stained samples were analyzed both manually and on theMICRO21 by three certified medical technologists. To generate a wider range of urinary constituents, 31 stained samples were created using serial dilution and enrichment. Using blinded experimental methods, the stained samples were reviewed manually, and processed by the MCRO21 and resultant images reviewed by the technologists.
Conclusion
There was no significant variation in the precision, reproducibility, and linear testing demonstrating the method. Correlation was demonstrated for RBC, WBC, Squamous Epithelial cells, Hyaline Casts, Amorphous, Calcium Oxalate, and Triple Phosphate Crystals, Mucous, Sperm and Yeast. The data presented support the claim that the MCCRO21 with Urine Sediment Analysis is safe and effective for it's intended use of locating, digitally storing and displaying microscopic fields of view from urine sediments in a urine slide for examination by a qualified individual for use in reporting a urine microscopic result.
