[0048] The invention relates to an analysis method of a urinalysis, comprising the following steps of, [0049] pouring a urine sample of a user subjected to a urinalysis over at least one reaction area (2) of a urine test strip (1) such that it is in contact with said area, [0050] taking an image of the urine test strip (1) enabled to contact with the urine with an image capturing unit (13), [0051] transmitting the image of the urine test strip (1) taken to a processing unit (5), [0052] recognizing the urine test strip (1) whose image is rendered by using the data in a reference chart (7) provided in a memory unit (6) by the processing unit (5) in the pattern of two columns and five rows, determining 10 reaction areas (2) on the strip, [0053] determining the color changes occurred in the reaction areas (2) of the urine test strip (1) selected, [0054] obtaining a urinalysis result by matching the data on the color changes determined with the data contained within a color scale (8) of the memory unit (6) in the processing unit (5), [0055] receiving the data of the user subjected to the analysis in the user profile from user data (10) contained within the memory unit (6) by means of the processing unit (5), [0056] determining the recommendation in which the user data received and said urinalysis results are matched in a recommendation pool (9), [0057] submitting the recommendation determined to the user.

[0058] A urine sample of a user subjected to a urinalysis is poured over at least a reaction area (2) of a urine test strip (1) such that it can penetrate into said strip. Then, an image of the urine test strip (1) is taken with an image capturing unit (13) of a mobile communication device (4). The image taken is transmitted to a processing unit (5) by the image capturing unit (13). The processing unit (5) determines the urine test strip (1) by receiving the data in a reference chart (7) part provided in a memory unit (6) together with the image transmitted.

[0059] Locations of the reaction areas (2) on the image of the urine test strip (1) determined are detected by matching the data provided in the reference chart (7) with their mathematical coordinates.

[0060] The color change in the reaction areas (2) of the urine test strip (1) matched with the reference chart (7) is analyzed by using the method of RGB histogram in the processing unit (5). Then, the color occurred/unchanged in each reaction area (2) is compared with a different color space again and the colors are recognized by eliminating the characteristics such as flashing, light intensity based on the differences defined relative to distance. The color changes occurred in each reaction area (2) are listed. A urinalysis result is obtained by analyzing the responses occurred by the color change in the reaction area (2) with the predetermined data.

[0061] Then, a recommendation is submitted to the user by using the data provided in a recommendation pool (9), and comparing the urinalysis results with the user data (10) kept in the memory unit (6) containing the data related to the user subjected to the urinalysis.

[0062] The image capturing unit (13) used in the said method is a camera.

[0063] The urine test strip (1) used in said method comprises at least one reaction area (2). Said reaction areas (2) are enclosed by at least one frame area (3). The reaction areas (2) are configured such as to change color by reacting with the urine that contacts to their surfaces. In an embodiment of the invention, the urine test strip (1) comprises a measuring area and a retaining portion having reaction areas (2) in two columns and five rows.

[0064] The frame area (3) in the invention is black in color. That the frame area (3) is black in color prevents flashing during the image rendering process. Furthermore, as the colors provided on the dark color are easy to perceive, the sensitivity of image rendering is promoted. Additionally, the reaction areas (2) have the frame areas (3) there between and the portion on which the reaction occurs is separated in parts. Thus, the reaction areas (2) are prevented from being disintegrated with the urine pressure and the image rendering is thereby facilitated.

[0065] A new design is developed with the analysis method of urinalysis according to the invention such that the faults of the urine test strip (1) in image rendering is minimized. In addition to this, a urinalysis can be carried out without any need for the high-quality image capturing units (13) thanks to the method developed.

[0066] The mobile communication device (4) used in said method is configured such as to communicate with other devices via a communication unit (11). The mobile communication device (4) has a display (12) that allows image display. The data provided from the display (12) is transmitted to a processing unit (5).

[0067] Said processing unit (5) and a memory unit (6) contained in the mobile communication device (4) are associated such that they can make data exchange with each other. Said memory unit (6) contains at least the reference chart (7), the color scale (8), user data (10) and data from the recommendation pool (9) therein. Moreover, the memory unit (6) is configured such as to be able to record data on the processing unit (5) and to have an access to the prerecorded data.

[0068] Said reference chart (7) contains the reference data of the physical characteristics of the urine test strip (1) including the size of the urine test strip (1), and the location map of each reaction area (2) and etc. Said color scale (8) is used to generate a result by comparing the color changes occurred in the reaction areas (2) with the reference colors.

[0069] Said user data (10) contain the prerecorded user profiles, and also, they are configured such that the data and profiles of a new user can be added as well. The user profiles in the user data (10) includes the data on user's height, weight, age, possibility of any chronic disease, eating pattern, exercise rate, step count per day, blood glucose level, heartbeat rate, tension measurements, stress level, blood oxygen level, etc. Said recommendation pool (9) is a memory unit (6) part used in generating a recommendation by matching the data in the user profile contained in the user data (10) of the user subjected to the urine test with the urinalysis results.

[0070] In another embodiment of the invention, the urinalysis results of the user can be submitted to another mobile communication device (4), a server, etc. via the communication unit (11) of the mobile communication device (4).

[0071] In a further embodiment of the invention, said mobile communication device (4) can be electronic communication devices such as a mobile phone, a tablet, a laptop computer, etc.

[0072] In a different embodiment of the invention, said display (12) can be a touch screen configured such as to allow the user to input data.

[0073] In another embodiment of the invention, said user data (10) include the user profiles containing various data for different users. Thus, it can be used in giving recommendation to the user by obtaining data on age, gender, chronic diseases and the like of the user subjected to the urinalysis.

[0074] One of the most important advantages of the invention is that it can be used in any environment and without any extra costs. For example, it can be conveniently used in the disadvantaged regions having limited health care services, houses, and small-sized hospitals without laboratories. This is particularly important related to people with a chronic disease and consistently in need for the urinalysis. Furthermore, the urinalysis results of the urine analyzed by using the data provided in the memory unit (6) by unskilled persons in the art can be obtained as well.

[0075] Moreover, thanks to the invention, the urinalysis results recorded on the user profiles can be monitored retrospectively. Thus, the user is easily able to have an access to his/her previous urinalysis results.
