It analyses biomarkers in the urine by employing electrochemical tests and detects the onset of kidney disease earlier than widely used kidney function tests. It also monitors kidney health to determine the stage of kidney disease.

- Non-disposable Reader The electrical signal collected from the disposable test platform is stored and processed in the reader in the predetermined format and is transmitted by a wired or wireless mechanism to any electronic platform.
- Kidney Health Monitoring Device [0028] Exemplary Development of Kidney Health Monitoring Device [0029] The present application provides an exemplary development of a non-invasive device to monitor renal health. This device detects and quantifies analytes excreted by kidneys to determine the stage of renal failure and other diseases associated with renal function impairment. The device can conduct a simultaneous estimation of multiple analytes by employing electrochemical tests and records the electrical behavior of the biomarkers in healthy and disease conditions.
- the device acts as a 24-hour (or continuous) urine sample analyzer to perform the kidney function tests, quantifies proteins (microalbumin, protein biomarkers), proteases and gelatinases, creatinine, urea, ions (calcium, potassium, sodium), a ratio of protein to creatinine and creatinine to urea to estimate the extent of kidney function impairment or renal failure.
- the Device Can Be Made as a Single-Use Device
- FIG. 1 is a schematic diagram of the components for and use of an exemplary system for kidney health monitoring.
- the device can be installed on a toilet bowl (A).
- the disposable part of the test platform is placed on or under the toilet seat (B) designed explicitly with electrodes and conductive traces (B).
- It is then connected to the non-disposable electronic device (wirelessly or wired) to record, monitor, and save the data (C).
- This device transmits the electrical conductivity data to an electronic device (D) such as a smartphone or tablet that can then further analyze or transmit the data to another electronic device to estimate the stage of the kidney disease and other urine tests required for the determination of kidney function.
- Steps B, C, and D can be combined in the same device
- the C and D are separate in this example.
- the test platform in the form of collection basket shaped to fit in a toilet or urinal may be disposable, such as made of paper with the electrodes and conductive traces printed on the paper, and the entire the collection basket is flushable.
- the collection basket is made of a non-flushable material and the basket is configured to remain in the toilet bowl over a period of time and perform multiple tests and record changes in the electrical behavior of the urine analytes.
- Figures 2A, 2B, 2C describe scenarios in which multiple tests are conducted on one disposable test platform (A) equipped with electrodes and fluid detectors (B) which are placed on a conductive platform to detect the electrical signatures of the analytes.
- the test platform has a number of microfluidic distribution channels for uneven distribution of the urine sample to different locations for simultaneous determination of multiple analytes using one urine sample test wells for the purpose of conducting tests simultaneously.
- the device in the figure has five test wells comprising a pair of electrodes in each test well.
- the test platform includes test wells for collecting urine, and each test well is composed of Polydimethylsiloxane (PDMS), but any other water repellant material can be used.
- PDMS Polydimethylsiloxane
- test wells are made with different diameters to accommodate different volumes of the test samples on the same platform.
- Each test well is attached to the fluid inlet by microfluidic channels of depth 500m, and widths of lOOpm, 200pm, 250 pm, 350 pm, and 500 pm for uneven distribution of the fluid to respective test wells in a given time.
- the number, length, width and/or height (dimensions) of microfluidic distribution channels that are open for urine flow can be increased or decreased based on test requirements.
- test wells are either coated with an electrochemical, and a conductive polymer or electrochemical is introduced into the device through the fluid inlet port.
- a level detector is attached to the device to further calculate the volume of the sample in each well of the known radius.
- Each well contains pair of electrodes inside the well, which are connected to the reader interface by conductive traces.
- the fluid inlet port is located at the center of the device to distribute the fluid to all the test wells via covered micro fluidic channels. As the fluid is filled in the wells, the conductivity of the sample is tested, and the information is transferred to the reader interface.
- the conductivity of the fluid in each well is monitored and recorded such as after every 20 seconds, and the data is recorded for a predetermined time which is a minimum of 20 seconds up to 24 hours.
- the data is then analyzed by the reader based on the signal ranges stored on the device.
- the test platform is composed of PDMS, and the electrodes are immersed in the test wells during the process of curing.
- the electrochemicals are introduced to the wells through the fluid inlet.
- the device is then bonded on the PCB to align electrodes with the conductive traces.
- the PCB is then attached to a multi-probe conductivity analyzer to record the changes in the electrical properties of the sample over time.
- the data is then analyzed by the reader and is processed to learn linear relationships in changes in conductance over time.
- the conductance values are converted to the amount of analyte present in the sample.
- the information is then correlated to the normal ranges of the analytes and stages of the renal disease to detect the disease and estimate the extent of
- FIGs 3A, 3B, 3C illustrate alternative forms of the disposable tester.
- the disposable barrier on this device is the container wall.
- the cap of the device (A) or the bottom of the device (C) is equipped with electrodes to record the electrical signature of the analytes for qualitative and quantitative estimation of biomarkers.
- the barrier is divided (B) to create separate environments in the same device.
- the position of the reader may be changed with respect to the position of the electrodes in the device.
- a urine collection cup was used with titanium and platinum electrodes.
- the lid or the bottom of the container was cut in 1 inch diameter to install the electrodes printed on the PCB.
- the PCB is physically glued to the container using water-repellant silicon-based glue.
- the electro chemicals were added to the container, and the baseline conductance is recorded using a multi-probe conductivity measurement device. To this device, urine sample was added, and the conductance was recorded as a function of time.
- the electrochemical mixtures added to the device vary based on the test. For example, for determination of total urinary proteins, a mixture of NaCl, functionalized PVA, L-arginine were added to the well in molar ratios 2:1:1, and the change is conductance was recorded over time. The reader then processed these electrical signals by subtracting the baseline conductance values from each reading and defining relationship between the conductance over time. We observed linear decrease in the conductance over time in response to the presence of urinary proteins.
- the rate of reaction determines the duration of the test. For example, the total ions can be estimated within 30 seconds. But the test for total proteins may require recording times longer than 2 minutes. The data is then collected by the reader for further processing.
- Figure 4 depicts another alternative scenario for the test platform where larger volumes of the test sample are needed for the test.
- the primary reservoir in this case, maybe a toilet bowl, urinal, or another container or equipment.
- the fluid is pumped into the test containers or test wells equipped with the electrolytes and connected to the reader.
- the tests can be conducted simultaneously or in series.
- the devices in Figures 2, 3, and 4 are used for conducting multiple tests or repeats of the same test.
- the electrochemical composition for each test is based on the time required to obtain the results.
- the device conducts measurements in sequence for each parameter based on time to reduce the errors in interpretation. For example, the results for the volume and temperature are obtained instantaneously.
- the results for total urinary proteins can be obtained in 2 minutes while we wait for 5 minutes to detect the presence of proteolytic enzymes.
- the computation for the test results for each test occurs at once. But the data for each test is stored as recorded.
- the system is developed for the measurement of six parameters simultaneously. But it can be designed and used for measuring a single parameter.
- Figure 5 shows the signal pathway from the device to the diagnostic outcome when a single test is to do for a single parameter.
- Figure 6 gives the process of monitoring a single parameter continuously over a predetermined time.
- Figure 7 shows the signal path for the scenario where multiple parameters are being analyzed at the sample time for a one-time sample.
- Figure 8 shows the process of monitoring multiple parameters at multiple time points or for the purpose of continuous monitoring. In an example, this method is used for simultaneous estimation of urinary protein, creatinine, and calcium over a 24-hour urine sample. The cumulative values were compared with the normal ranges of the analytes to diagnose a disease condition.
- the computation of the test starts after 3 minutes when the electrical signals for both the tests are available.
- the data is then processed to find the linear relationship between electrical signal and time.
- the electrical signal is then converted to values in mg/dl, and then the ratio of the amounts is computed.
- filters can be employed to reduce the noise. Every sample can be measured with an on-off switch or a proximity sensor, and then the device can add the values over 24 hours to give a reading for a 24-hour urine test.
- the data interpretation is made based on the available known values for the analytes in the urine samples.
- the data is then presented using an electronic platform in the form of values of each analyte and stage of kidney disease.
- the presence of microalbumin more than 30 mg in 24 hours urine sample was considered an early sign for renal disease, and more than 300 mg in 24 hours was considered as advanced renal disease.
- the amounts less than 30mg were considered as a normal range.
- the values of microalbumin were correlated with values obtained from the urinary creatinine test to estimate the extent of renal function impairment.
- the universally used normal ranges were used in all the tests performed.
- the data can be transmitted directly from the disposable part of the device or the non disposable reader. For reliable results, data is transmitted from the reader to an electronic platform.
- the data can be transferred by a wired connection, Bluetooth, or by a wireless connection to store on a cloud-based platform or a server using any means of existing or novel data transfer protocols.
- “plurality” means two or more. As used herein, a “set” of items may include one or more of such items.
