IDEXX VetLab* UA* Analyzer Operator's Guide
English Version
Introduction
The IDEXX VetLab* UA* Analyzer (UA analyzer) is a reflectance photometer designed to read and evaluate IDEXX UA Strips for canine, feline and equine urine only. The UA analyzer reads the test strips, saves the results to memory and prints them on its own internal printer.
The UA analyzer eliminates factors known to affect the visual evaluation of urine test strips, such as variable lighting conditions at the workplace, people's individual skills at matching colors and corresponding concentration ranges, different reaction times for test pads on the strips, clerical errors and color artifact imparted by some urine samples.
The IDEXX VetLab UA Analyzer, IDEXX UA* Strips, and IDEXX VetLab* UA* Calibration Strips are designed for veterinary use only.
IDEXX VetLab* Station Connectivity
The IDEXX VetLab UA Analyzer is part of the IDEXX VetLab* suite of analyzers, all of which connect to the IDEXX VetLab Station (IDEXX's laboratory information management system). Connecting multiple analyzers to the IDEXX VetLab Station helps you attain a comprehensive picture of your patient's health, with the ability to view test results from multiple analyzers on a single report, determine disease progression with parameter-trending capabilities, and more.
By connecting the UA analyzer to the IDEXX VetLab Station, you can:
- Automatically review patients' prior results on every printout, for easy comparison.
- Improve client communications with illustrated diagnostic or treatment progress printouts.
- Link to expert descriptions and common causes of abnormal values.
- Print information to help explain the significance of results to your clients.

How it Works
A prepared IDEXX UA Strip is placed on the test strip tray, which moves it into the analyzer and under the reading head. The analyzer reads the gray reference pad first, and then reads each of the test pads on the strip. Results are available in approximately 80 seconds.
IMPORTANT: Only IDEXX UA Strips can be used with the IDEXX VetLab UA Analyzer.
The analyzer contains light-emitting diodes (LEDs) that emit light at various wavelengths. Reading is done electro-optically, as follows:
[Diagram Description: Light from an LED passes through a test pad on a strip. A phototransistor detects the reflected light. This analog signal is converted to digital by an A/D converter and processed by a microprocessor to produce a semi-quantitative result.]
The LED emits light of a defined wavelength onto the surface of the test pad at an optimum angle. The light hitting the test zone is reflected more or less intensely depending on the color produced on the test pad, and is picked up by the detector, a phototransistor positioned directly above the test zone. The phototransistor sends an analog electrical signal to an A/D converter, which changes it to digital form. The microprocessor then converts this digital reading to a relative reflectance value by referring it to a calibration standard. Finally, the analyzer compares the reflectance value with the defined range limits (reflectance values that are programmed into the analyzer for each parameter) and outputs a semi-quantitative result.
Installing the IDEXX VetLab UA Analyzer
- Unpack the IDEXX VetLab UA Analyzer and place it on a stable, level surface. Choose a well-ventilated area away from obvious sources of heat, direct sunlight, cold, humidity, or vibrations. For optimum results, room temperature should be at 68°F−78°F (20°C−26°C) and relative humidity at 30%−60%.
IMPORTANT: Allow the UA analyzer to acclimate to room temperature for two to three hours before operating it for the first time.
- Connect the power cord and the AC adapter. Then, connect the AC adapter to the power socket at the rear of the analyzer and plug the power cord into an outlet.
NOTE: Use only the power adapter supplied (which is marked as supplying 7.5 V DC, 3000 mA). The cords from other power adapters may fit in the power socket of the UA analyzer, but may have the incorrect voltage or current for this analyzer. Using a different power adapter than the one supplied may impact results or render the analyzer unusable.
- Hold the test strip tray with the gray reference pad facing up. Slide it into the slot below the function keys so that the edge of the tray is flush with the edge of the analyzer.
IMPORTANT: Be careful not to touch the gray reference pad. Contamination of the reference pad may impair the quality of the results.
- Load the printer paper. To release the printer cover, press the raised dots immediately below the cover. After the cover pops open, lift it back.
Place the paper roll in the compartment and pull out the first few inches of paper to just beyond the edge of the compartment. The thermosensitive side of the paper (the outer surface of the paper roll) should be facing downward.
Close the cover by pressing it until it locks audibly.
- Select the printing, units, and connection (interface) options (for more information, see pages 20-21).
NOTE: If your UA analyzer is connected to the IDEXX VetLab Station, you can turn off the analyzer's print option, but you must still have paper in the analyzer. UA analyzer results will be transferred to the IDEXX VetLab Station automatically and included in the patient's integrated diagnostic report.
Connecting to the IDEXX VetLab Station
Connecting your IDEXX VetLab UA Analyzer to the IDEXX VetLab Station computer lets you identify your patient and automatically transfer urinalysis results to the patient's record.
To connect the UA analyzer to the IDEXX VetLab Station computer:
- Verify the UA analyzer is set to bidirectional mode (for more information, see “Modifying the Interface Options” on page 20).
- Power off the UA analyzer and the IDEXX VetLab Station computer.
- Plug the interface cable into the UA analyzer and the IDEXX VetLab Station.
- Power on the analyzer and the IDEXX VetLab Station. When the UA icon appears on the Home screen on the IDEXX VetLab Station computer, your connections are complete.
NOTE: If the UA icon does not appear, contact IDEXX Technical Support (see “IDEXX Technical Support Contact Information” on pages 37–38).
Powering on the Analyzer
- Turn on the IDEXX VetLab UA Analyzer using the on/off switch on the back of the analyzer. The analyzer automatically performs a self-check. After the self-check is complete, the test strip tray returns to its start position and the retaining bar opens. "Self Check OK" prints on the printout along with a date-and-time stamp.
- Customize the language and date/time settings (if necessary) and then press the Start button to save your changes and return to the ready-to-measure mode. For more information on setting the language, date, and time, see pages 22-23.
- Before using the UA analyzer, it must be calibrated using the IDEXX VetLab UA Calibration Strips.
- After the self-check is complete, the “Repeat Calibration” message appears on the display. Press the Yes key to advance to the calibration mode.
NOTE: If the “Start Calibration” message is not displayed, then the UA analyzer is in the ready-to-measure mode and will display the “Insert Strip” message. Press the Calibr key to advance to the calibration mode.
- Place an IDEXX VetLab UA Calibration Strip, with the pads facing upward, on the tray so that its leading edge is held by the clip at the front end of the insertion slot. The retaining bar must be open.
IMPORTANT: Be careful not to touch the pads on the calibration strip and do not allow them to come into contact with urine.
IMPORTANT: Only IDEXX VetLab UA Calibration Strips can be used with the IDEXX VetLab UA Analyzer.
- Press the Start button. During the calibration process, a beep will sound, the test strip tray will move in and out of the analyzer, and the retaining bar will open and close. Do not remove the calibration strip until the “Calibration OK” message prints. After the calibration is complete, “Calibration OK” and a date-and-time stamp appear on the printout and the analyzer reverts to ready-to-measure mode.
- Remove and dispose of the calibration strip. Use each calibration strip only once.
NOTE: For more information about calibrating the analyzer, see pages 26–27.
- After the self-check is complete, the “Repeat Calibration” message appears on the display. Press the Yes key to advance to the calibration mode.
Using the IDEXX VetLab UA Analyzer
Overview
The IDEXX VetLab UA Analyzer's display menu and function keys provide an easy-to-use interface. The first line of the display menu provides system status and user information. The second line of the display menu provides options for the three function keys.
Self-Check
When you turn on the UA analyzer, the self-check function automatically runs to ensure that the software code plug, the tray transport mechanism, the printer connection and the optical system are all functioning properly. After the self-check is complete, “Self Check OK” prints on the printout, along with the date-and-time stamp, and then the analyzer displays the ready-to-measure mode.
Reading IDEXX UA Strips
The IDEXX VetLab UA Analyzer is very easy to use. Simply insert an IDEXX UA Strip when the “Insert Strip” message appears, which indicates the analyzer is in the ready-to-measure mode.
IMPORTANT: Only IDEXX UA Strips can be used on the IDEXX VetLab UA Analyzer. Do not use any other brand of strips.
NOTE: If the analyzer requires attention, a notification appears on the display menu. See the “Troubleshooting” section on pages 29–34 for more information.
IMPORTANT: Always wear protective gloves when handling and disposing of veterinary samples. Dispose of used test strips according to the regulations for handling potentially infectious material.
To read a test strip:
- If your UA analyzer is connected to the IDEXX VetLab Station, always initiate the sample on the IDEXX VetLab Station. For more information, see the IDEXX VetLab Station Operator's Guide.
- Use fresh urine that has not been centrifuged. Thoroughly mix the urine sample. The sample should be at room temperature when the test is performed and should not have been standing for more than one hour.
- Use a pipette to flood the IDEXX UA Strip with the urine sample, making sure that all the test pads are moistened. Do not bend the strip.
- Briefly (approximately one second) dab the long edge and then the back of the test strip on an absorbent surface (e.g., a paper towel).
- Place the test strip, with the test pads facing up, on the test strip tray so that its leading edge is held firmly by the clip at the insertion slot. The retaining bar must be open. Approximately 2 mm of strip must be held under the clip.
- Press the Start button. A beep sounds. The tray advances slightly and the retaining bar closes. Each time a test strip is read, the gray reference pad in the tray is evaluated for temperature and aging effects that may influence the optical system.
IMPORTANT: Ensure that the retaining bar is locked into place and that the test strip is in the correct position. If the test strip is not correctly located in the middle of the tray, move it gently to the side until it is properly aligned.
The test strip tray automatically pulls the test strip into the analyzer so it can be read and then returns to its start position. Do not remove the test strip until the analyzer returns to ready-to-measure mode. It takes approximately 80 seconds from when you press the Start button until all measurements are complete.
- The UA analyzer prints the test results and the next sequence number appears on the display menu.
NOTE: If the UA analyzer is connected to the IDEXX VetLab Station, test results are transmitted automatically.
- Remove and dispose of the test strip. Wipe any urine residue from the tray with a lint-free wipe. For more information about cleaning the tray, see “Cleaning the Test Strip Tray" on page 25.
Sending Results to the IDEXX VetLab Station Computer
If the IDEXX VetLab UA Analyzer is connected to the IDEXX VetLab Station computer, data transmission occurs automatically. However, you can manually transmit data, as needed. For more information see “To Manually Send Results to the IDEXX VetLab Station” on page 20.

Maintenance
Overview
It is recommended that you:
- Clean the test strip tray daily.
- Calibrate the analyzer weekly.
- Keep the exterior parts and surfaces of the analyzer clean.
- Upgrade software promptly.
Cleaning the Test Strip Tray
IMPORTANT: Always wear protective gloves when handling the test strip tray.
At the end of each day, clean the tray using the following procedure:
- Turn off the IDEXX VetLab UA Analyzer and pull the test strip tray out of the analyzer.
- Rinse the contaminated parts of the test strip tray under running water and then clean it with 70% isopropyl alcohol (if necessary). Slight crystalline deposits, especially those contaminating the retaining bar mechanism or the cogs on the underside of the test strip tray, can be removed with a soft brush. Dry the tray with a lint-free wipe.
IMPORTANT: Be careful not to damage the gray reference pad during cleaning, and ensure that it is completely clean and dry before reading a test strip.
IMPORTANT: Ensure that the positioning hole on the side of the tray is absolutely dry and clean. This hole is used to ensure that the test strip tray is positioned correctly in the analyzer.
- With the retaining bar nearest to you, slide the tray into the slot below the function keys so that the edge of the tray is flush with the edge of the analyzer.
- Turn on the UA analyzer. The self-check begins automatically and verifies that the reference pad is in good condition and that the positioning hole in the test strip tray is unobstructed. If not, a notification will appear (see the "Troubleshooting" section on pages 29–34).
Calibrating the IDEXX VetLab UA Analyzer
The IDEXX VetLab UA Analyzer is calibrated before it leaves the factory. After you have installed the UA analyzer, you must recalibrate it using the IDEXX VetLab UA Calibration Strips before you begin reading test strips. The UA analyzer must be recalibrated every seven days thereafter.
The IDEXX VetLab UA Calibration Strips consist of a gray plastic material that is standardized to give constant, defined reflectance readings. Calibrating the analyzer compensates for aging effects that influence the optical system and the gray reference pad in the test strip tray.
IMPORTANT: IDEXX VetLab UA Calibration Strips should be stored on their side.
To calibrate the IDEXX VetLab UA Analyzer:
- Ensure that the test strip tray is clean and dry.
- Press the Calibr. key on the display menu. The “Start Calibration” message appears.
- Place an IDEXX VetLab UA Calibration Strip, with the test pads facing upward, on the tray so that its leading edge is held by the clip at the front end of the insertion slot. The retaining bar must be open.
IMPORTANT: Be careful not to touch the test pads on the calibration strip and do not allow them to come into contact with urine.
IMPORTANT: Only IDEXX VetLab UA Calibration Strips can be used with the IDEXX VetLab UA Analyzer.
- Press the Start button. A beep sounds. The tray advances slightly, the retaining bar closes, and the gray reference pad on the tray and the calibration pads are read. After the calibration is complete, the tray returns to its start position and the retaining bar opens. If the calibration is valid, the result is stored with the date and time, and is printed.
NOTE: To cancel a calibration run, press Stop on the Display menu screen or power off and then power on the UA analyzer.
- Remove and dispose of the calibration strip. Use each calibration strip only once.
Weekly Calibration Reminder
Regular calibration, every seven days, is necessary to ensure the quality of the results obtained. IDEXX cannot warrant the validity of results if the analyzer is not calibrated regularly.
“Repeat Calibration” will appear in the menu display to remind you to perform the weekly calibration. Running a calibration strip takes approximately 80 seconds. You can recalibrate the UA analyzer at any time.
Calibration Printout
If the calibration results are within the defined range, the “Calibration OK" message automatically prints with the date and time, as well as a list of reflectance values for measuring positions 1–11 for the orange LED (middle column of values) and green LED (right column of values).
Cleaning the Case
Always disconnect the power cable before cleaning the IDEXX VetLab UA Analyzer.
Clean the outside of the UA analyzer with a lint-free cloth dampened with a suitable disinfectant (10% bleach or isopropyl alcohol), ensuring no liquid enters the analyzer. Do not use any of the following near the analyzer: organic solvents, ammonia-based cleaners, ink markers, sprays/ disinfectants containing volatile liquids (except isopropyl alcohol), insecticides, polish, or room freshener.
Care should be taken not to spill any samples, chemicals, cleaning agents, water, or other fluids on/into the UA analyzer.
Note: Dust and animal hair can lead to analyzer failures. Routinely dust off the UA analyzer with a damp cloth and dust around its location.
Replacing the Printer Paper
- Press the raised dots immediately below the cover to release the printer cover. After the cover pops open, lift it back.

| Values obtained are different when compared with those from visual evaluation | The test strip is not properly positioned on the test strip tray. | Repeat the test using a new IDEXX UA strip. Ensure the test strip is properly aligned in the middle of the tray before processing. For more information, see “Reading IDEXX UA Strips” on page 15. |
| The urine on the test strip has dried. | Repeat the test using a new IDEXX UA Strip. For more information, see “Reading IDEXX UA Strips” on page 15. | |
| Strong urine color. | The analyzer uses the compensation pad on the IDEXX UA Strip to compensate for the strong color. Since this is not possible to do visually, the analyzer's reading is more accurate. | |
| No Printout | The printer is not powered on. No paper has been inserted or the paper roll is finished. | Change the printer setting to On. For instructions, see “Printer Settings" on pages 20–21. Load or replace the printer paper. For more information, see "Replacing the Printer Paper” on page 27. |
