The UriSed is a professional urine sediment analyzer, which is able to detect urine particles in urine sediment with high accuracy. This instrument performs sample preparation, takes several pictures of each sample through its built-in microscope and evaluates them using the UriSed Evaluation Module which is a high quality image processing software. This is a revolutionary new method for sedimentation, identification and classification of urine particles.

 

The UriSed system consists of four parts:

 

  • UriSed   systemThe Measuring Unit includes centrifuge, microscope, and other mechanical parts. This unit is responsible for performing sample preparation and taking the whole viewfield microscopic images. The measurement technique of the instrument is a world novelty: it is the automatic centrifugation and microscopic measurement of native urine samples in special disposable cuvettes. This patented technology is actually the automation of the well-known traditional manual urine microscopy.
  • The second part consists of wash and waste containers. For the proper cleaning of the instrument simple distilled water is enough, there is no need for special detergents.
  • The operating PC is responsible for the control of the main unit and evaluating the images by a sophisticated image processing software.
  • The last part consists of different peripherals like monitor, keyboard, mouse and optional printer.

 

The results of the measurements together with all the images are  stored in the memory of UriSed, which is large enough to store 5000 records. Stored results can be studied on the monitor of the UriSed PC, sent to the

Laboratory Information System

or can be printed out by external printer.

The UriSed microscopic urine sediment analyzer is a stand-alone instrument, which can be connected to the LabUMat urine strip reader. Together, the two instruments make up a Complete Urine Laboratory System.

  • Preparation of the instrument for measurement only takes a few seconds. UriSed only needs standard distilled water for washing its pipette, and disposable plastic cuvettes for the observation of samples under its built-in microscope. 600 cuvettes can be inserted at once into the instrument, which should be enough for a day in most laboratories. After filling up the washing container and loading the cuvette holder, UriSed is ready for sediment analysis, no further preparation is needed.
  • To perform a measurement, the operator only has to pour urine sample into a standard test tube and install it on the rack mover part of the instrument in the supplied rack. The rest is performed automatically.
  • Firstly, the test tube is forwarded automatically to the sampling position. The urine sample is then mixed up by the pipette. (The pipette is the sample probe of UriSed.) This is to assure the homogeneity of the sample. In the next step, the  urine sample is aspirated and transferred into a special disposable cuvette. For an accurate evaluation, UriSed needs only 2.0 mL urine sample in the test tube. However, in the course of the measurement only 0.2 mL is used.
  • After transferring the sample, the pipette is moved to the back of the instrument into a special washing unit. There both the inner and outer shell of the pipette is cleaned with distilled water in order to prevent carryover between different urine samples. This is a unique washing technique which does not require a special cleaning solution.
  • The cuvette with the urine sample inside is then forwarded into the built-in centrifuge. The time and speed of centrifugation is optimized to prevent particle destruction, while creating a sediment layer at the bottom of the cuvette.
  • Afterwards, the cuvette is forwarded to the microscope position, where 5-10-15 or 20 images are taken by the built-in camera, through the built-in microscope. The images are taken at different positions of the specimen after setting the focus plane automatically to the sediment layer at each position.
  • In the course of the measurement process, recorded whole viewfield images are evaluated automatically by the UriSed Evaluation Module, which is a high quality image processing software.
  • At the end of the process, the used cuvette is placed into the waste bin. Meanwhile, the following sample is already being prepared for microscopic investigation.

The UriSed has the very unique advantage, that it can provide not only images of individual particles, but also whole viewfield images of the microscope.


The UriSed Images are HPF-like images, the magnifications of which correspond to the standard 400x enlargement, which is usually used in laboratory practice. The UriSed Images as well as 10 regular HPF images of 20x concentrated urine sediment correspond to about 2.5 µl native urine. That is why in the course of the measurement process, UriSed takes 15 images by default.


As a direct result all images can be accessed and displayed separately on screen from the user software. This is one of the most significant advantages of UriSed, because in that way no information can be lost; not only the automatically detected particles, but all details can be seen on the stored images.


On the images recognized particles are identified and labeled by captions above them. As the final result, general statistics (quantitative concentration values and semi-quantitative category ranges) are calculated for each sample, which include the average of all the images taken from the given sample. This is the most significant added value of UriSed. Thanks to the impressive performance of the UriSed Evaluation Module the accuracy, sensitivity and specificity values of the automatic evaluation of different particles are in most cases over 80%, which fulfills the requirements of routine urine sedimentation.
