How it works
The uChekTM system consists of a smartphone app ("The uChek app") and a peripheral kit ("The uChek kit"),
The uChek app is currently available for iPhone 4, 4S and 5 and can be downloaded from the App Store.
The uChek kit contains the Cuboid, the ColorMat and 5 test strips. It can be obtained from our shop.
A urine dipstick is a strip of paper which has different test pads impregnated with different chemicals which change color when dipped in urine. The color change, that happens gradually over a specified time period after dipping the strip, helps you identify the concentration of different analytes in urine. Commercially, available urine dipsticks can give information of upto 12 analytes in urine. Urine dipsticks may be read visually, via timely comparison with a color chart provided by the strip manufacturer or via the use of a machine such as a semi-automated urine analyzer.
The uChek urine analyzer may be used in 2 modes.
In Manual mode, the uChek app merely assists the process of visual inspection, providing time-keeping and manual data logging functionality. The stored results may be analyzed as a trend over time, or sent via email.
In Auto mode, the uChek system ("uChek App" and "uChek Kit" together) perform the function of a semi-automated urine analyzer machine. The system may be used to automatically record the test strip result and log test data. The uChek app uses the phone's camera and processor for image capture, processing the images and generating results. The results may be stored, analyzed as a trend over time, or sent via email.
The usage of uChek in Auto mode is illustrated below, in 5 simple steps.

Accuracy and Usability
The uChekTM urine analyzer has been tested extensively at two sites with approximately 800 samples with the iPhone 4, 4S and 5. uChek has been found to be accurate with 100% readings within +/- 1 color block of a urine dipstick. This makes the performance of uChek comparable with commercially available semi-automated urinalysers.
Find below a summary of studies documenting the performance of uChek.
If you represent a University, healthcare body or clinical organization and would like your organization's study on uChek to be included in this list, please let us know.
Independent study conducted by Nanobios Lab, Department of Biosciences and Bioengineering, Indian Institute of Technology (Bombay), April 2013 Note from authors: "uChek, a mobile urinalysis system developed by Biosense Technologies Pvt Ltd was tested for accuracy against a commercially available semi-automated urine strip reader. The uChek system operated with Siemens 10SG strips was tested against negative and positive controls. Output was cross checked visually (n=20, each). To reduce experimental errors, the controls were also tested with Dirui 10P urine test strips marketed by Aspen Diagnostics Pvt Ltd," Note from authors: "The results suggest equal and more than 95% accuracy with respect to both Dirui's strips used with the semi-automated urine strip reader and visual correlation. The study report is currently being prepared for publication in an indexed international journal."

1. Why is urine tested ?
Urine can say a lot about the health of humans and pets. Urine analysis using commercially available test strips (often referred to as "dipsticks") can provide semi-quantitative concentration of analytes like glucose, protein, ketones, urobilinogen, bilirubin, specific gravity, blood, pH, leukocytes and nitrites. This is an example of an in vitro diagnostic test, and often provides useful information about the status of carbohydrate metabolism, kidney and liver function, acidbase balance and bacteruria. A typical application for dipsticks is checking for urinary tract infections, for example. Automatic analysis of urine test strips using automated urine test strip analyzers is a well established practice in modern day urinalysis.
2. What does the uChek system consist of ?
The uChek system consists of a smartphone app ("The uChek app") and a peripheral kit ("The uChek kit"), Check here for more details on how it works.
3. What are urine dipsticks ?
A urine dipstick is a strip of paper which has different test pads impregnated with different chemicals which change colour when dipped in urine. The colour change helps identify the concentration of different analytes in urine. Commercially available urine dipsticks can give information of upto twelve analytes in urine.
4. Why do I need the uChek kit ?
The uChek kit contain the ColorMat and Cuboid. The Color Mat helps your smartphone camera to identify the colour change correctly in your urine dipstick by correcting for local illumination conditions. It will automate the tedious process of manually checking the urine dipsticks at specific time periods for the colour change. The Cuboid is an enclosure with a designated placement area for the smartphone, and an aperture through which your phone camera can peep at the ColorMat and strip inside. The Cuboid's setup prevents errors associated with movement of the phone, or stray shadows that may affect the image processing. It has been carefully designed to perform, in conjunction with the uChek app, the function of a semi-automated urinalysis system.
In addition to the Cuboid and the ColorMat, the uChek kit contains five samples of five different types of dipsticks that the uChek system currently supports – so that you can choose which dipstick suits your requirement, and get trained in its use.
5. How accurate is uChek ?
uChek is comparable in accuracy to many commercially available semi-automated urinalysis machines, when used correctly. Check here for more information on accuracy and usability studies conducted with uChek,
6. Is uChek a medical device ? Is it registered with the FDA?
